However, this did not come to be due to the format of the high school drama competition, which is held within the year up to the block competition and the national competition, but Mizukami graduated from high school in that subsequent year, thus he was unable to compete for the national competition.<ref name=":0" /> Originally, he had planned to go to college and continue playing baseball, but after participating in the prefectural tournament, he began to desire becoming an actor. After being initially opposed to his choice, his parents finally changed their minds after being impressed by his acting debut.<ref name=":0" />
