Before he was famous, Atsushi attended an Industrial high school in his hometown of Shimonoseki. He was suspended twice during that time, once for smoking and once for cheating on a test. Atushi was also a member of a band before becoming interested in comedy. For his first comic act, Atsushi teamed up with a classmate from school. They called themselves Umaseki Fugutarou and Fugunosuke, a name they derived from Shimonoseki, and fugu or pufferfish, a dish famous in the region. Atsushi eventually teamed up with Ryo Tamura after relocating to Tokyo. They chose to go by “London Boots” initially because it was the name of a fictional comedy team who themselves took it after some high-heeled shoes. While “London Boots” does not have any particular meaning in English, in Japanese it refers to the knee length platform shoes worn by some Japanese girls. Recently he's being the vocalist of the band jealkb.
