City Connection announced Jajamaru's Hyakki Yakouden, a new hack-and-slash action game in the Ninja Jajamaru-kun series, during the Pixel Arcadia showcase streamed on August 25, 2026. The game is set for release in 2027 on Nintendo Switch 2, PS5, and PC via Steam, where a store page opened the same day. The title was first teased at the City Connection 20th Anniversary Thanksgiving Festival in December 2025, but this announcement revealed the platforms and shifted the release window from 2026 to 2027. Developed jointly by City Connection's team, which worked on the previous Jajamaru's Yokai Daikessen, and Amazing, known for Venus Eleven Vivid!, the game follows Jajamaru as he searches dungeons for the kidnapped Princess Sakura. Players use over 300 types of equipment, including ninja swords, kusarigama, and shuriken, and pass through glowing torii gates to trigger Hyakki Yakou Parades with special battle rules. Clearing dungeons teaches ninjutsu, and a base room allows stat and equipment upgrades, plus furniture that affects stats. The story culminates in a fight against the yokai general Nuraripiyoko. Western publishing is handled by Clear River Games.
The announcement trailer and Steam store page went live on August 25, 2026, giving players their first look at the game's yokai-filled dungeons. The series, which marked its 40th anniversary in 2025, now moves into a genre it has not previously explored, with hack-and-slash combat replacing the platforming of earlier entries.
Development is a joint effort between City Connection's in-house team, which handled Jajamaru's Yokai Daikessen, and Amazing, the studio behind Venus Eleven Vivid!. The game's story sees Jajamaru searching for Princess Sakura, who has been kidnapped, with stages set in factories, alleyways, hot springs, and snowy mountains. The familiar partner Gamapakkun also appears.
Gameplay revolves around clearing dungeons that serve as party venues for yokai, with over 300 equipment types available. Passing through glowing torii gates triggers Hyakki Yakou Parades, where battles occur under special rules. Players can challenge boss yokai who lead large groups, and winning grants treasure. A base room allows players to strengthen stats and equipment, and furniture items obtained in dungeons also affect Jajamaru's stats.
Western publishing is handled by Clear River Games, and wishlist registration is already open on Steam.
