"Ganbare Goemon (がんばれゴエモン), known as Legend of the Mystical Ninja, Mystical Ninja, and Goemon in North America and the PAL region, is a long-running video game series produced by Konami.
These games revolve around the main character Goemon, and his exploits. As the name suggests, his character was loosely based on Ishikawa Goemon, the noble thief of Japanese folklore. While the early games of this title emphasized Goemon as a noble thief, he eventually becomes more of a standard video game hero character. His trademarks are his blue bushy hair and weapon of choice, the Kiseru. The games are set in a cartoony, mystical Feudal Japan, where every bit of folklore and legend about Japan is true. Although the series has its roots in action adventure, the Ganbare Goemon series has features from genres including RPG, puzzle games, and board games. Ganbare Goemon has proven to be widely popular in Japan. Along with its many video games (with more being produced to this day), it has spawned a wide series of merchandise and several anime and manga series.
Despite its popularity in Japan only four of its games have been released overseas: three for the Super Nintendo and Nintendo 64 consoles, and one for the Game Boy)."
