- Not to be confused with Yoko Mizumoto, who is now known as Yoko Wada.
Yoko Wada is a Japanese composer and sound designer. She was the main composer for SIMS and composed most (if not all) of their Sega Master System and Game Gear games. While she was working at SIMS, a game credited a Yoko Yamamoto only once for music. This could be Yoko, but this has not yet been confirmed.
Yoko used several aliases throughout her career, likely due to requirements at the companies she worked for. In most games, she used the moniker Nasubi, which is Japanese for "Eggplant". The etymology of this name is unknown.
