Keiko Tamura is a Nintendo employee with an unused credit in Super Metroid. Her role in the game, and the order of her credit is unknown. It is possible that she was a translator for the game, as she was a translator for Metal Combat: Falcon's Revenge, EarthBound and Kirby's Avalanche around the same time. In the years since, Tamura has been credited in many other roles, including localization, English script, product management, voices (Killer Instinct and its sequel), map modeling and coordination. Her most recent credit is as the lead level designer for Klonoa, the 2008 Wii remake of Klonoa: Door to Phantomile.
