He started his career at 17 as a professional cabaret singer in the Ginza district in Chūō, Tokyo, when moving to Tokyo in 1952. He started working in various nightclubs singing his favourites from the French chansons such as those of Édith Piaf, Yvette Guilbert and Marie Dubas. His claim to fame came rather early in 1957, with a smash-hit called "Me Que Me Que", which included a string of profanities not used in media at the time. He was also renowned for his effeminate beauty, making him a hit with the media. He performed a monthly show at Shibuya Jean-Jean called "Akihiro Miwa no Sekai" (the world of Akihiro Miwa) from the 1970s until its closure in 2000, as well as touring Japan.
