Fan-made Ultima Japanese localization Mod page opens on Steam
The Mod translates the Ultima series from the first game onward, including the 3D dungeons of the first five titles.
Individual developer Hige Taku has published the project page on Steam for a Japanese localization Mod covering the Ultima series, according to gamespark.jp. The project page went up on November 9, 2026.
The Mod localizes the games from the first Ultima title onward into Japanese. In the first five Ultima games, which combine a 2D overworld map with underground 3D dungeons, the 3D dungeons are also being localized.
With the patch, the original versions of Ultima III: Exodus and Ultima IV: Quest of the Avatar become playable in Japanese, in addition to the Famicom versions that were released in Japan.
