Naoto OTA began his acting career in 1983 in a show on the national channel NHK, Dakara Seishun Nakimushi Kôshien. This drama was about the adventures of high school students entering the Kôshien, the big annual baseball championship. Spotted by producers, he auditioned for Bioman (Chôdenshi Bioman). Naoto OTA was auditioning for the part of Red One but got the role of Shingo TAKASUGI, aka Green Two. After the show ended, he appeared a few times in other productions and changed his first name in the 90s, becoming Takahiko OTA.

He put an end to his career in 1993 and became an entrepreneur. He managed several small companies, including currently a chiropractic clinic whose chief resident is Akito OSUGA, Bioman’s Blue Three, with whom he has been friend for 35 years.


As Bioman is turning 35 this year, Japan Expo is bringing together the full team of the show to celebrate the event with them. Let’s celebrate this show that has become legendary for early pop culture fans with Michiko MAKINO (Pink Five)Akito OSUGA (Blue Three), Naoto OTA (Green Two), Ryôsuke SAKAMOTO (Red One)Sumiko TANAKA (Yellow Four II), and Kazuo NIIBORI (Red One stunt actor).

Created in 1984 by Toei, Bioman is super sentai TV show, a genre featuring superheroes in costumes fighting evil. The eighth series of this type in Japan, Bioman brought innovations like featuring two women among the five heroes, Yellow Four and Pink Five.

Its 51 episodes initially aired in 1984 and 1985 in Japan and soon also in France, first in 1985 and again in 1987. It was a success and the show became a must for the audience at the time.

Synopsis: The once prosperous Planet Bio is destroyed after a world war erupted over the use of a scientific discovery called "Bio Particles". The Planet Bio Peacekeeping Alliance, which sought to use Bio Particles for peaceful purposes, sends the giant robot Bio Robo and an assistant robot named Peebo to prevent the same tragedy from happening on Earth. Bio Robo arrives in 15th century Japan, where it showers Bio Particles on five young individuals. Five centuries later, the descendants of these individuals, infused with Bio Particles, are chosen by Peebo and Bio Robo to become the Bioman team to protect the Earth from the New Empire Gear, an organization led by mad scientist Doctor Man.
