The '''Bonin Islands'''<!-- Japanese in #Name section -->, also known as the {{nihongo|'''Ogasawara Islands'''|小笠原諸島|lead=yes}}, are a Japanese archipelago of over 30 subtropical and tropical islands located around {{convert|1000|km|mi|lk=out|sp=us}} SSE of Tokyo and {{convert|1000|mi|km|sp=us|order=flip}} northwest of Guam.<ref>{{Cite news|url=https://www.japantimes.co.jp/news/2018/07/12/national/history/ogasawara-islands-remote-witnesses-front-lines-japanese-history/|title=Ogasawara Islands: Remote witnesses on the front lines of Japanese history|last=Yoshida|first=Reiji|date=2018-07-12|work=The Japan Times Online|access-date=2019-09-25|issn=0447-5763}}</ref><ref name=Coppock /> The group as a whole has a total area of {{convert|84|km2|sp=us}} but only two of the islands are permanently inhabited, Chichijima and Hahajima. Together, their population was 2,560 as of 2021. Administratively, Tokyo's Ogasawara Subprefecture also includes the settlements on the Volcano Islands and the Self-Defense Force post on Iwo Jima. The seat of government is Chichijima.

Because of the Bonins' isolation, many of their animals and plants have undergone unique evolutionary processes. They have been referred to as the "Galápagos of the Orient" and were named a Natural World Heritage Site in 2011. When first reached during the early modern period, the islands were entirely uninhabited, although subsequent research has found evidence of some prehistoric habitation by Micronesians. Upon their repeated rediscoveries, the islands were largely ignored by the Spanish, Dutch, and isolationist Japanese until finally being claimed by a passing British captain in 1827. American, European, and Hawaiian colonists arrived from the Kingdom of Hawaii in 1830. Subsequently, Meiji Japan successfully colonized and reclaimed the islands in 1875, but Bonin Islanders' community continued up to World War II, when most islanders were forcibly relocated to Honshu. Following Japan's defeat, the US Navy occupied the island, bulldozing existing Japanese homes and restricting resettlement until full control of the Bonins was returned to Japan in 1968. Ethnically, the island is now majority Japanese but remains unusually diverse, which is reflected in the local Creole language known as Bonin English. Improved transportation has made agriculture more profitable and encouraged tourism, but the development required for an airport remains a contentious local issue.

{{Anchor|Etymology|Toponymy|Name}}

==Names== The name ''Bonin'' comes from an 1817 article in the French {{lang|fr|Journal des Savans}} by Jean-Pierre Abel-Rémusat in which{{mdash}}among various other misunderstandings of his source material{{sfnp|Kublin|1953|p=35}}{{mdash}}he misread a description of the islands as uninhabited ({{lang|ja|無人嶋}}, "desert island[s]") for their actual name, used the wrong reading of the characters ({{Lang|ja-Latn|buninshima}} for {{Lang|ja-Latn|mujintō}}), and then transcribed the resulting reading incorrectly into French as {{lang|fr|Bo-nin Sima}},{{sfnp|Rémusat|1817|p=390}}{{sfnp|Kublin|1953|p=36}} which eventually lost its original hyphen.

The name ''Ogasawara'' ({{lang|ja|{{linktext|小笠原}}}}; {{IPA|ja|ogasawaɾa}}) literally means "little hat-shaped field(s)" but is used for the islands in honor of Ogasawara Sadayori ({{lang|ja|小笠原 {{linktext|貞|頼}}}}), a supposed ancestor of the ronin Ogasawara Sadatō ({{lang|ja|小笠原 {{linktext|貞|任}}}}) fictitiously credited with the discovery of the chain. Within Japanese, the Bonins proper are known as the "Ogasawara Islands" or "Group" ({{lang|ja|小笠原{{linktext|群島}}}}, {{Lang|ja-Latn|Ogasawara-guntō}}) while the "Ogasawara Islands" or "Archipelago" ({{lang|ja|小笠原{{linktext|諸島}}}}, ''Ogasawara-shotō'') is a wider term including the other islands of the Ogasawara Municipality ({{lang|ja|小笠原{{linktext|村}}}}, ''Ogasawara-mura'') and its coterminous Ogasawara Subprefecture ({{lang|ja|小笠原{{linktext|支庁}}}}, ''Ogasawara-shichō''){{mdash}}namely, the Volcano Islands and three remote islands of Nishinoshima, Minamitorishima, and Okinotorishima. These islands are parts of Japan's Nanpō Islands.

The islands were also formerly known to Europeans as the '''Archbishop Islands''' ({{langx|es|Islas del Arzobispo}}), probably in honor of Pedro Moya de Contreras, archbishop of Mexico and viceroy of New Spain, who sent an expedition to the area in the late 16th century.<ref name="Moriarty & Roberts"/>

==History==

===Prehistory=== At the end of the 20th century, prehistoric tools and carved stones were discovered on North Iwo Jima and Chichijima, establishing that the islands were previously home to at least some members of an unknown Micronesian people.<ref name="history">{{citation |url=http://www.iwojima.jp/ogasa2.html |title=小笠原・火山(硫黄)列島の歴史 |lang=ja |last= |first= |date= |publisher= |location= }}.</ref>

===Early modern period=== The first recorded visit by Europeans to the islands happened on 2 October 1543, when the Spanish explorer Bernardo de la Torre on the ''San Juan'' sighted Haha-jima, which he charted as ''Forfana''.{{sfnp|Welsch|2004}} The islands were uninhabited at that time. Japanese discovery of the islands occurred in ''Kanbun'' 10 (1670) and was followed by a shogunate expedition in ''Enpō'' 3 (1675).<ref>Tanaka, Hiroyuki (1993). [http://japanese.human.metro-u.ac.jp/kokubun/bonins/04tanaka.htm "''Edo Jidai ni okeru Nihonjin no Mujin Tou (Ogasawara Tou) ni tai-suru Ninshiki''" ("The Ogasawara Islands in Tokugawa Japan").] {{webarchive|url=https://web.archive.org/web/20071225144611/http://japanese.human.metro-u.ac.jp/kokubun/bonins/04tanaka.htm |date=2007-12-25 }} ''Kaiji Shi Kenkyuu''(''Journal of the Maritime History''). No. 50, June, 1993.</ref> The islands were then referred to as {{nihongo|Bunin jima|無人島|''Buninjima''}}, literally "the uninhabited islands". Shimaya Ichizaemon, the explorer at the order of the shogunate, inventoried several species of trees and birds, but after his expedition, the shogunate abandoned any plans to develop the remote islands.{{sfnp|Rüegg|2017}}

The first published description of the islands in the West was brought to Europe by Isaac Titsingh in 1796. His small library of Japanese books included {{Nihongo3|''An Illustrated Description of Three Countries''|三国通覧図説|Sangoku Tsūran Zusetsu}} by Hayashi Shihei.<ref>WorldCat, [http://www.worldcat.org/search?q=Sangoku+Ts%C5%ABran+Zusetsu&qt=results_page ''Sangoku Tsūran Zusetsu'']; alternate romaji [http://www.worldcat.org/search?q=Sankoku+Ts%C5%ABran+Zusetsu&qt=results_page ''Sankoku Tsūran Zusetsu'']</ref> This book, which was published in Japan in 1785,<ref>Cullen, Louis M.

These groups were collectively called the Archbishop Islands in Spanish sources of the 18th–19th century, most likely due to an expedition organized by Pedro Moya de Contreras, archbishop of Mexico and viceroy of New Spain, to explore the northern Pacific and the islands of Japan. Its main objective was to find the long sought but legendary islands of ''Rica de Oro'' ("Rich in Gold"), ''Rica de Plata'' ("Rich in Silver"), and the ''Islas del Armenio'' ("Islands of the Armenian"). After several years of planning and frustrated initial attempts, the expedition finally set sail on 12 July 1587, commanded by Pedro de Unamuno. Even if it did revisit the Daitō Islands, already charted by Bernardo de la Torre in 1543, the expedition could not find the wanted islands after searching the positions where they were charted in contemporary references.<ref name="Moriarty & Roberts">{{cite journal|author1=James R.

===19th century=== On 12 September 1824, American Captain James Coffin in the whaler {{ship||Transit|1817 ship|2}} first visited the southern group of islands (''Coffin Islands''). He revisited the archipelago in 1825, but this time, he arrived at the middle group of islands (''Beechey Group'').{{sfnp|Chapman|2016|p=27}}

In September 1825, the British whaling ship ''Supply'' landed in the southern Bailey Group of islands. In 1826, another British whaler, ''William'', arrived at Beechey Island.{{sfnp|Chapman|2016|p=27}} Whaling ships called regularly for water and turtles before continuing their voyages.<ref>''The National Cyclopaedia of Useful Knowledge, Vol.II,'', (1847) London, Charles Knight, p.205.</ref>

In 1827, Captain F. W. Beechey of {{HMS|Blossom|1806|6}} reached the island chain and claimed them as a British possession.{{sfnp|Beechey|1831}} A copper plate was removed from ''Blossom''{{'}}s hull and left on a beach as a marker of the claim:{{Blockquote|text=HBM Ship ''Blossom'' Capt F.

O. | title =Historical Relic | journal =The Journal of the Polynesian Society | volume =53 | issue =4 | page =211 | date =December 1944 | jstor =20702990 }}</ref>}}

He also named the island of Chichijima "Peel" after then British Home Secretary Sir Robert Peel.<ref name=Coppock /> Beechey was also surprised to find two men living on the islands. They remained on the islands after the ''William'' left the year before in 1826. The men were Wittrein and Petersen.{{sfnp|Chapman|2016|p=27}}

In 1830, with the help of the British Consul to the Sandwich Islands (Hawaii), Richard Charlton, Richard Millichamp, and Matteo Mazzaro sailed to the islands.{{sfnp|Chapman|2016|p=27}} The first permanent colony was made up of Nathaniel Savory of Bradford, Massachusetts, America, Richard Millichamp of Devon, England; Matteo Mazzaro of Ragusa/Dubrovnik, Austrian Empire (now in Croatia); Alden B. Chapin and Nathaniel Savory of Boston; Carl Johnsen of Copenhagen; as well as seven unnamed men and 13 women from the Kingdom of Hawaii.<ref>Notes on the Bonin Islands, Michael Quin, ''Journal of the Royal Geographical Society of London'', Vol. 26, (1856), pp. 232–235, Blackwell Publishing on behalf of The Royal Geographical Society (with the Institute of British Geographers)</ref> They found the climate suitable for farming and the raising of livestock. Rum was made from cane sugar, and bordellos were opened, sometimes staffed by women kidnapped from other island chains. Whalers and other ships that could not find another friendly port in Japan often visited the Bonins for provision and recreation.<ref>Coppock, p. 61</ref>

Two years later, the Oriental Translation Fund of Great Britain and Ireland published a posthumous, abridged publication of Titsingh's French translation of {{Lang|ja-Latn|Sankoku Tsūran Zusetsu}}.{{sfnp|Klaproth|1832|p=256}}

Further settlers arrived in 1846 aboard the whaling ship ''Howard''. They established themselves initially in South Island. One of them, a woman from the Caroline Islands named Hypa, died in 1897 at the age of about 112, after being baptized on her deathbed.{{sfnp|King|1898}}

Commodore Matthew C. Perry of the United States Navy visited the islands in 1853 and bought a property at Port Lloyd from Savory for $50. The US "Colony of Peel Island" (Chichijima) was created, and Savory was appointed governor.<ref>{{Cite book |last=Rüegg |first=Jonas |url=https://www.cambridge.org/core/books/kuroshio-frontier/A3240222992D53CAAAB0223267DEFEB8 |title=The Kuroshio Frontier: Empire and Environment in the Making of Japan's Pacific |date=2025 |publisher=Cambridge University Press |isbn=978-1-009-53457-4 |series=Cambridge Oceanic Histories |location=Cambridge |doi=10.1017/9781009534611}}</ref>

In 1853 there were Peel Island 31 inhabitants, made up as follows; four English, four American, one Portuguese, the rest being natives from either the Sandwich, the Ladrones, the Caroline or Kingsmill islands, together with children born on the Bonins.<ref>[http://nihongo.hum.tmu.ac.jp/~long/bonins/robertson.htm The Bonin Islands]</ref>

[[File:Ogasawara Islands in the Pre-war Showa era.JPG|thumb|left|A village in the Bonins during the early Shōwa period]] In January 1862 (Bunkyū 1), the Tokugawa shogunate of Japan claimed the islands in a short-lived colonial enterprise. The shogunal steamboat ''Kanrin Maru'' was dispatched to the islands with a crew of cartographers, physicians, and prominent bureaucrats. The islands were officially renamed Ogasawara, referring to the legendary Japanese discoverer from the late 16th century. This tentative colonization, however, did not last for long. In the summer of 1863, under foreign pressure, the shogunate ordered the evacuation of the islands.{{sfnp|Rüegg|2017}}

In 1875, the Japanese Meiji government reclaimed the islands.<ref>[https://books.google.com/books?id=sr-yzZK-WRgC&pg=PA175 Language and Citizenship in Japan, edited by Nanette Gottlieb, Chapter 10, p. 176].</ref> The Japanese names of each island were resolved, and 38 settlers from Hachijojima were sent the following year. In 1876, the islands were put under the direct control of the Home Ministry. Further foreign settlements were banned, and the government assisted settlers who wished to relocate from mainland Japan. The islands' forests were also reduced to use the land for sugar cane production. Colonists largely segregated themselves in two different villages, one for the Bonin Islanders and the other for the Japanese.<ref name=Coppock /> Bonin Islanders were eventually granted Japanese nationality in 1882.

===20th century=== Lionel Cholmondeley compiled a history of the islands over several years, publishing it in 1915.{{sfnp|Cholmondeley|1915}}

In 1917, 60–70 Bonin islanders claimed ancestry among the 19th-century English-speaking settlers; however, in 1941, no Bonin people would acknowledge descent from these early colonists.<ref>''National Geographic'', October 1944, pp. 387–388, 404.</ref> The current residents include some who claim to be related to Nathaniel Savory.<ref>{{cite web |url=http://www.ogasawara-channel.com/contents/mouriso.htm|title=父島の宿|access-date=2007-09-05}}</ref> In the winter of 1920–1921, Russian Futurist painter David Burliuk lived in the Bonin Islands and painted several landscapes of the islands.<ref>{{cite book |last=Société Anonyme |author-link=Société anonyme |title=Société Anonyme (the First Museum of Modern Art, 1920–1944): Monographs |url=https://books.google.com/books?id=pEJOAAAAYAAJ |access-date=2013-05-20 |year=1972 |publisher=Arno Press |isbn=978-0-405-00772-9 |page=87}}</ref>

Bonin Islanders could either become Japanese nationals or receive American citizenship and repatriate to the United States. The majority remained in the islands as Japanese citizens. Initially, 600 Japanese relocated to the islands, growing to about 2,000 by the end of the 20th century.<ref name=Coppock />

==Economy== Historically, the Bonin Islands consisted of subsistence farming with some exploitation of timber and grazing land for export to the mainland. With improved transportation, it has developed as a tourist destination, particularly for Japanese interested in scuba diving and ecotourism. Foreign tourists are also sometimes drawn by the islands' remoteness and unusually mixed local culture. Refrigeration has also allowed for the greater exportation of fruits and vegetables. Coffee bushes have also recently been introduced successfully.<ref>[https://world-natural-heritage.jp/en/food/ogasawara-food/ Experience the distinctive cuisine of Ogasawara, born from its uncommon island environment]</ref>

Some government agencies are also involved with the islands. A {{convert|25|m|ft|adj=mid|-diameter}} radio telescope is located in Chichijima, one of the stations of the very-long-baseline interferometry (VLBI) Exploration of Radio Astrometry (VERA) project. It is operated by the National Astronomical Observatory of Japan.

The Bonin Islands consist of three subgroups. Their former names come from a variety of sources, but their Japanese ones generally reflect a family: * Muko-jima Group ({{lang|ja-Hani|聟島列島}} {{transliteration|ja|Muko-jima Rettō}}), formerly the Parry Group **Muko-jima ({{lang|ja-Hani|聟島}}, {{literally|Bridegroom Island}}) **Yome-jima (嫁島, {{lit|Bride Island|lk=no}}), formerly Kater Island **Nakōdo-jima or Nakadachi-jima (媒島, {{lit|Matchmaker Island|lk=no}}) **Kita-no-jima (北の島 or 北島, {{lit|Northern Island|lk=no}}) **Mae-jima (前島, {{lit|Front Island|lk=no}}), formerly The Ears * Chichi-jima Group (父島列島 {{transliteration|ja|Chichi-jima Rettō|lk=no}}), formerly the Beechey Group **Chichi-jima (父島, {{lit|Father Island}}), formerly the Main Island or Peel Island **Ani-jima (兄島, {{lit|Elder Brother Island|lk=no}}), formerly Hog Island or Buckland Island **Otōto-jima (弟島, {{lit|Younger Brother Island|lk=no}}), formerly North Island or Stapleton Island **Mago-jima (孫島 {{lit|Grandchild Island|lk=no}}) **Higashi-jima (東島 {{lit|East Island|lk=no}}) **Nishi-jima (西島 {{lit|West Island|lk=no}}), formerly Goat Island **Minami-jima (南島 {{lit|South Island|lk=no}}), formerly Knorr Island * Haha-jima Group (母島列島 {{transliteration|ja|Haha-jima Rettō|lk=no}}), formerly the Baily Group or Coffin Islands **Haha-jima (母島, {{lit|Mother Island}}), formerly Hillsborough Island **Mukō-jima (向島, {{lit|Yonder Island|lk=no}}), formerly Plymouth Island **Hira-jima or Taira-jima (平島, {{lit|Flat Island|lk=no}}) **Ane-jima (姉島, {{lit|Elder Sister Island|lk=no}}), formerly Perry Island **Imōto-jima (妹島, {{lit|Younger Sister Island|lk=no}}), formerly Kelly Island **Mei-jima (姪島, {{lit|Niece Island|lk=no}})

Although not part of the {{Nihongo|Bonins|小笠原群島|Ogasawara-'''guntō'''}} geographically,{{sfnp|Freeman|1951|pp=229–235}} the nearby Volcano Islands, Nishinoshima (Rosario Island), Okinotorishima (Parece Vela), and Minamitorishima (Marcus Island) are organized as part of {{Nihongo|Ogasawara municipality|小笠原村|Ogasawara-'''mura'''}}.<ref>[https://www.britannica.com/EBchecked/topic/73107/Bonin-Islands "Bonin Islands,"] ''Encyclopædia Britannica.''

== Geology == The Bonin Islands are a part of the Izu–Bonin–Mariana arc of Pacific islands. A fore arc, they lie above the subduction zone where the Pacific Plate slides beneath the Philippine Sea Plate. This began during the Eocene, simultaneously producing the deep Bonin Trench to the east about 50 million years ago and prolonged volcanic activity that created the islands on the west around 48 million years ago. The Bonins are mostly composed of an andesitic volcanic rock called boninite, rich in magnesium oxide, chromium, and silicon dioxide. They may represent the exposed parts of an ophiolite that has not yet been emplaced on oceanic crust. Although the area is currently dormant, most of the islands still have steep shorelines, often with sea cliffs ranging from {{convert|50|to|100|m|ft|sp=us}} high.<ref name=como/>

The Volcano Islands are much younger and still geologically active. Iwo Jima is a dormant volcano characterized by rapid uplift and several hot springs. The highest point in the entire chain lies on South Iwo Jima, at {{convert|916|m|ft|sp=us}}. In November 2013, a new volcanic island formed offshore from Nishinoshima and eventually merged with it.<ref>{{cite web |title=Nishinoshima Continues to Grow |url=https://earthobservatory.nasa.gov/images/86111/nishinoshima-continues-to-grow |website=Earth Observatory |publisher=NASA |access-date=20 June 2020 |date=24 June 2015}}</ref>

The islands are fringed with healthy coral reefs and have many small beaches.<ref name=como>[http://www.coremoc.go.jp/english/pub/coralreefjapan/060101_ogasawara.pdf coral reefs] {{webarchive |url=https://web.archive.org/web/20080410061717/http://www.coremoc.go.jp/english/pub/coralreefjapan/060101_ogasawara.pdf |date=April 10, 2008 }}</ref>

==Climate== The climate of the Bonin Islands ranges from a humid subtropical climate (Köppen climate classification ''Cfa'') to tropical monsoon climate (Köppen climate classification ''Am'').

The climate of Chichijima is on the boundary between the humid subtropical climate (Köppen classification ''Cfa'') and the tropical monsoon climate (Köppen classification ''Am''). Temperatures are warm to hot all year round due to the warm currents from the North Pacific gyre surrounding the island. Rainfall is less heavy than in most parts of mainland Japan since the island is too far south to be influenced by the Aleutian Low and too far from Asia to receive monsoonal rainfall or orographic precipitation on the equatorward side of the Siberian High. The wettest months are May and September, while the driest are January and February.

==Ecology== {{main|Ogasawara subtropical moist forests}}

===Flora===

[[File:Ogasawara Islands, Tokyo, Japan.jpg|thumb|right|Kominato beach and Kopepe Beach, Chichi-jima]]

Flora have evolved differently on each of the islands. The Bonin Islands are sometimes referred to as the Galápagos of the Orient.<ref>{{Cite news|last =Yamaoka| first =Fumiko| title =Saving an endangered bird in 'Orient's Galápagos'|newspaper =The Japan Times| date =May 12, 2007| url = http://search.japantimes.co.jp/cgi-bin/nn20070512f1.html}}</ref><ref name="world heritage"/> They form a distinct subtropical moist broadleaf forest ecoregion, the Ogasawara subtropical moist forests. The ecoregion has a high degree of biodiversity and endemism. The islands are home to about 500 plant species, of which 43% are endemic. The forests are of three main types:<ref name="eoe">"Ogasawara subtropical moist forests". ''Encyclopedia of Earth''. Accessed 28 July 2020. [https://editors.eol.org/eoearth/wiki/Ogasawara_subtropical_moist_forests]</ref>

*Type I: ''ElaeocarpusArdisia'' mesic forest is found in moist lowland areas with deep soils. The forests have a closed canopy with a height of about {{convert|15|m|ft|sp=us}}, dominated by ''Ardisia sieboldii''. ''Elaeocarpus photiniaefolius'', ''Pisonia umbellifera'', and ''Planchonella obovata'' are other important canopy species. These forests were almost completely destroyed by clearing for agriculture before 1945. *Type II: ''DistyliumRaphiolepisSchima'' dry forest is found in drier lowland and upland sites with shallower soils. It is also a closed-canopy forest, with a {{convert|4|to|8|m|ft|sp=us|adj=on}} canopy composed mostly of ''Distylium lepidotum'', ''Rhaphiolepis integerrima'', ''Schima mertensiana'', ''Planchonella obovata'', and ''Syzygium buxifolium''. The Type&nbsp;II forests can be further subdivided into: **Type IIa: ''Distylium-Schima'' dry forest occurs in cloudy upland areas with fine-textured soils. These forests contain many rare and endemic species, with ''Pandanus boninensis'' and ''Syzygium buxifolium'' as the predominant trees. **Type IIb: ''Raphiolepis-Livistona'' dry forest is found in upland areas with few clouds and rocky soils. ''Rhaphiolepis integerrima'' is the dominant tree species, along with the fan palm ''Livistona boninensis'', ''Pandanus boninensis'' and ''Ochrosia nakaiana''. *Type III: ''Distylium-Planchonella'' scrub forest is found on windy and dry mountain ridges and exposed sea cliffs. These forests have the highest species diversity on the islands. ''Distylium lepidotum'' and ''Planchonella obovata'' are the dominant species, growing from {{convert|0.5|to|1.5|m|ft|sp=us}} tall. Other common shrubs are ''Myrsine okabeana'', ''Symplocos kawakamii'', and ''Pittosporum parvifolium''.<ref name = eoe/>

These islands are home to the northernmost outliers of the palm genus ''Clinostigma''. ''Clinostigma savoryanum'' is endemic and has been planted in Mediterranean climates with success. Other unique species include ''Metrosideros boninensis'', a plant related to similar species growing in Fiji and New Caledonia.

===Fauna=== Due to its isolation and recent colonization, the Bonin Islands contain several endemic animal species, most of them recently extinct.

==== Birds ==== [[File:BOPE.JPG|thumb|right|A Bonin petrel]]The range of the Bonin petrel extends beyond the Bonins themselves to other islands in the North Pacific. There are two restricted-range species of birds on the islands, the Japanese wood pigeon ({{lang|la|Columba janthina}}) and the near-threatened Bonin white-eye ({{lang|la|Apalopteron familiare}}), formerly known as the Bonin honeyeater. The Japanese wood pigeon was extirpated from the Iwo Island groups in the 1980s. The formerly endemic Bonin pigeon ({{lang|la|C. versicolor}}), Bonin thrush ({{lang|la|Zoothera terrestris}}) and Bonin grosbeak ({{lang|la|Carpodacus ferreorostris}}) are now extinct.<ref name="birdlife">"Bonin Islands" ''Avibase – Bird Checklists of the World''.

==== Mammals ==== A small extinct bat, Sturdee's pipistrelle, is only known in one record and has not been seen since 1915.

[[File:Port of Futami, Chichijima, Ogasawara.jpg|thumb|right|Futami Port, Chichi-jima, Ogasawara Village]] The main port is Futami on Chichijima. Since 2016, the main line connecting the islands to the mainland is the Ogasawara Shipping Company ({{lang|ja|小笠原海運株式会社}}). It operates the ''Ogasawara Maru'' ({{lang|ja|おがさわら丸}}), an 11,035-ton {{convert|150|m|sp=us|adj=on}} long vessel with 170 private rooms and a total capacity of 894 passengers.<ref name=boatymcboatface>{{cite web |url=http://www.ogasawara-channel.com/access/ogamaru.htm |title=おがさわら丸 (''Ogasawara Maru'') |date=2022 }}</ref> With a top speed of {{convert|24.7|knot|km/h mph|sp=us}}, it makes the trip from Takeshiba Pier in Tokyo in about 24 hours in good weather.<ref name=boatymcboatface/> The number of monthly voyages varies, having fallen during the coronavirus pandemic.

===Road transport=== Ogasawara Village operates a bus service on Chichijima and elderly passengers may use a "silver pass". There is also a sightseeing taxi service, a rental car company, motorized scooter rental services, a bike rental service, and other amenities. Bringing your automobile onto the island is extremely difficult and costly.

===Air transport=== The Bonins have no airport. During severe accidents, illnesses, and other emergencies, a helicopter is dispatched from the Self-Defense Force (SDF) post on Iwo Jima. The ''ShinMaywa US-1'' seaplane from the SDF post at Iwakuni is used during visits by the Tokyo governor and other dignitaries and for any emergency requiring rapid transport back to Honshu.

For several decades, there has been talk of building a full airport.<ref>{{cite book|title = Ogasawara Shotō Kōkūro Kaihatsu Chōsa Hōkusho: Ogasawara Shotō no Shinkōjiritsu no tameni|trans-title = Ogasawara Island Airlines Development Study Report: For the Independence of the Ogasawara Islands|language = ja |editor = Tōkyōto Sōmukyoku Santama Tōsho Taisakushitsu Ogasawara Shinkōka|publisher = Tokyo Metropolitan Government |year = 1983}}</ref><ref>{{cite book|title = Ogasawara Shotō Kōkūro Kaihatsu Chōsa Hōkusho: Ogasawara Shotō no Kōkūjuyō Yosoku|trans-title = Ogasawara Island Airlines Development Study Report: Estimated Air Transportation Demand for Ogasawara Islands|language = ja |editor = Tōkyōto Sōmukyoku |publisher = Tokyo Metropolitan Government |year = 1985}}</ref><ref>{{cite book|title = Ogasawara Shotō Kōkūro Kaihatsu Chōsa (sono 2) Hōkusho: Shūkō Kizai tō Chōsa oyobi Kūkō Kensetsu-an Sakutē Chōsa |trans-title = Ogasawara Island Airlines Development Study Report: Survey of Air Service Equipment and others with Study on Planning Airport Construction |language = ja |editor = Tōkyōto Sōmukyoku |publisher = Tokyo Metropolitan Government |year = 1987}}</ref><ref>{{cite book|title = Ogasawara kūkō kensetsu kēkaku tō ni kansuru teigen |trans-title = Recommendations on Ogasawara Airport Construction |language = ja|author = Ogasawara kūkō kensetsu kēkaku tō senmon iinkai |editor = Tōkyōto Sōmukyoku Gyōseibu Chiiki Shinkōka|publisher = Tokyo Metropolitan Government|year = 1998}}</ref> Sites on Chichijima and Anijima have both been rejected.

This includes a significant proportion of Bonin Islanders (ancestors from the United States, Europe, and other Pacific islands), who can often be distinguished by their physical features, family names spelled out with katakana, and adherence to Christianity. During and after the US military occupation of 1946–1968, a small minority of islanders opted for US citizenship and/or emigrated from the islands. However, most Bonin islanders now appear to be reassimilating with the ethnic Japanese majority.

Japanese is the common language.
