All Night Nippon
Ever since the beginning Ohtsuki was the band's frontman, and in order to promote the band he began appearing on All Night Nippon as a radio personality. From there he started to appear in various forms of media, even in talk shows like "Tetsuko no Heya". Ohtsuki says he was extremely nervous on his first appearance on "Tetsuko no Heya", and could hardly manage to answer the questions he was being asked.
