The party was formed by Kawamura in April 2010. After briefly holding several seats in the national legislature, the party merged at the national level with the [[Tomorrow Party of Japan]] in November 2012 before that party's dissolution in May 2013. Genzei Nippon remained a separate party at the regional level and has been active within [[Aichi Prefecture]]. As well as Kawamura, the party has thirteen members serving on the Nagoya city council and three members serving on the [[Aichi Prefectural Assembly]].
In October 2023, it was announced that the party would be affiliated on the national level with [[Naoki Hyakuta]]'s [[Far-right politics|far-right]] [[Conservative Party of Japan]], but the relationship was severed in September 2025 after a feud between Kawamura and Hyakuta.
==History== The party was founded by [[Takashi Kawamura (politician)|Takashi Kawamura]], then the mayor of Nagoya, and registered with the [[Aichi Prefecture|Aichi Prefectural]] electoral commission on 26 April 2010.<ref name=found>{{cite web |url=http://news.yahoo.co.jp/pickup/1935917 |title=新政治団体「減税日本」設立＝市議会解散へ布石−河村名古屋市長 |trans-title=New political group "Genzei Nippon" established - Nagoya mayor Kawamura preparing for city council election |language=Japanese |date=26 April 2010 |access-date=16 March 2016 |archive-date=8 February 2017 |archive-url=https://web.archive.org/web/20170208073357/http://news.yahoo.co.jp/pickup/1935917 |url-status=dead }}</ref> At a press conference held on the same day, Kawamura emphasized the point that the greatest support that politicians can provide to citizens is a reduction in taxes.<ref name=found/>
The party first gained representation in the [[national Diet]] in May 2011 when [[Yuko Sato (politician)|Yuko Sato]], the representative for the [[Aichi 1st district]] in the [[House of Representatives (Japan)|House of Representatives]], officially resigned from the ruling [[Democratic Party of Japan]] (DPJ).<ref name=Sato>{{cite web|url=http://www.asahi.com/politics/update/0513/TKY201105130258.html |title=民主、佐藤夕子氏の離党届受理 減税日本初の国会議員に |trans-title=DPJ accepts Yuko Sato's defection, Genzei Nippon's first national Diet member |language=Japanese |publisher=[[Asahi Shimbun]] |date=13 May 2011 |archive-date=16 May 2011 |archive-url=https://web.archive.org/web/20110516152225/http://www.asahi.com/politics/update/0513/TKY201105130258.html |access-date=16 March 2016}}</ref> Sato had lodged her resignation with the party in March in order to provide support to Genzei Nippon's candidates in the Nagoya city council election, but her application was put on hold while DPJ officials considered expulsion instead.
Two more DPJ members of the House of Representatives, [[Koki Kobayashi]] from the [[Tokyo proportional representation block]] and [[Toshiaki Koizumi]] of the [[Ibaraki 3rd district]], left the party to join Genzei Nippon in August 2012.<ref>{{cite web|url=http://www.japantimes.co.jp/news/2012/08/18/national/latest-dpj-defectors-to-join-nagoya-force/ |title=Latest DPJ defectors to join Nagoya force |publisher=Japan Times |last=Johnston |first=Eric |date=18 August 2012 |access-date=16 March 2016}}</ref> On 31 August, the three representatives joined with fellow DPJ defector [[Tomoyuki Taira]] to form the ''Genzei Nippon-Heian'' voting block within the House of Representatives, with Koizumi as the leader.<ref name=Ugoki>{{cite web |url=http://www.shugiin.go.jp/internet/itdb_annai.nsf/html/statics/ugoki/h24ugoki.pdf/$File/h24ugoki.pdf |title=衆議院の動き 第20 号 |trans-title=House of Representatives Activity Vol. 20 |language=Japanese |pages=492–496 |date=March 2013 |access-date=16 March 2016}}</ref>
DPJ representatives [[Atsushi Kumada]] ([[Osaka 1st district]]) and [[Tomohiko Mizuno]] ([[Southern Kanto proportional representation block|Southern Kanto block]]) joined Genzei Nippon in October 2012, giving the party five Diet members, the minimum requirement for registration as an official party.<ref>{{cite web|url=http://www.asahi.com/special/minshu/TKY201210290103.html |title=民主の熊田・水野両議員が離党へ 減税日本への合流検討 |trans-title=DPJ's Kumada and Mizuno defect, considering joining Genzei Nippon |language=Japanese |date=29 October 2012 |access-date=16 March 2016}}</ref> The party was registered with Kawamura as the leader on 31 October 2012.<ref name=Ugoki/> On 13 November, Taira, who had remained an independent within the House, left the voting block to join [[Your Party (Japan)|Your Party]], which led to the voting block being renamed ''Genzei Nippon''.<ref name=Ugoki/>
On 22 November 2012, the party merged at the national level with the Anti-TPP, Zero Nuclear Party, which had been established just three days prior, to form the ''Tax Reduction, Anti-TPP, Zero Nuclear Party''.<ref name=Ugoki/> A few days later this group further merged into the [[Tomorrow Party of Japan]] in order to contest the [[2012 Japanese general election|2012 general election]]. Genzei Nippon continued to exist at the regional level following the national mergers, led by Kawamura. In the [[2015 Japanese unified local elections|2015 unified local elections]], the party won 12 seats on the 75-seat Nagoya city council.<ref>{{cite web |title=開票結果-政令市議選・愛知県【統一地方選2015】 |trans-title=Election Results - Designated city council elections: Aichi Prefecture (Unified local elections 2015) |url=http://www.yomiuri.co.jp/election/local/2015/kaihyou/yi23.html |access-date=16 March 2016 |publisher=Yomiuri Shimbun |language=Japanese}}</ref>
On 17 October 2023, during the first press conference and party meeting of the newly-founded [[Conservative Party of Japan]], it was announced that Genzei Nippon would be affiliated nationally with the Conservative Party, with Kawamura becoming the Conservative Party's vice president.<ref name=":0">{{Cite web |last= |date=2023-10-17 |title=名古屋 河村市長「日本保守党」共同代表に就任 |url=https://www3.nhk.or.jp/news/html/20231017/k10014228101000.html |archive-url=https://web.archive.org/web/20231018021057/http://www3.nhk.or.jp/news/html/20231017/k10014228101000.html |url-status=dead |archive-date=18 October 2023 |access-date=2023-11-11 |website=NHK}}</ref>
Around the time of the election, reports emerged of internal tensions between Hyakuta and Kawamura regarding the party's management. In September 2025, Diet member Yuko Takegami, a close ally of Kawamura, left the party, citing disagreements with Hyakuta and Kawamura's marginalization in leadership decisions. Later that month, the party announced it was severing ties with Genzei Nippon, and Kawamura was removed from his position as co-leader. Kawamura was reportedly considering forming a new party in response.<ref>{{cite news |date=3 October 2025 |title=日本保守党「愛知県は特に力を入れる」 河村たかし氏の離党、新党設立報道で対決姿勢鮮明 |trans-title=Japan Conservative Party: "We will put particular effort into Aichi Prefecture" - Takashi Kawamura leaves party, reveals confrontational stance amid reports of new party formation |url=https://www.sankei.com/article/20251003-K3UKZKA5YJBGBGRKAURUM35FOQ/ |access-date=3 October 2025 |work=Sankei Shimbun |language=ja}}</ref>
