Play JaJaMaru no Daibouken Online

Summary

JaJaMaru no Daibouken, known simply as JaJaMaru, arrived on Japan’s Family Computer in 1986 and never saw an official Western release. The game drops you into the role of a bright‑red ninja who darts through stylized, Japan‑inspired stages, each teeming with mischievous spirits that need to be dispatched.
Your attacks are simple but satisfying, letting you clear swarms of foes with a single swipe. A quirky twist appears when you locate a hidden frog companion; once rescued, the frog becomes a ride that lets you hop over obstacles and zip past enemies. The blend of classic platforming and this oddball mount gives the title a charm that still feels fresh to retro fans.
