Okakichi has announced that it will shut down its entire Changokushi series of mobile NFT games in early 2026. The blockchain game project spearheaded by Yoshiki Okamoto will have its curtains closed after running for just over a year. [Thanks, 4Gamer.]
For the record, Changokushi was originally teased as Project K, which was an attempt by Yoshiki Okamoto in the blockchain scene before his planned retirement in 2027. The roguelite auto-battle RPG Changokushi! Kekkon-shiyou was the first game in the series that launched in 2024.
As of this announcement, there have been a total of five Changokushi mobile games released in Japan. The other four games are a real-time action strategy, a Vampire Survivors-like roguelike action, a shooter RPG, and an idle RPG.
Okakichi also separately announced that the KUSOGeeeeee marketplace platform hosting the NFT characters for Changokushi games will close down in March 2026. The company will hold a buyback session beforehand, so that existing users who still own the NFT characters can get reimbursed with the following tier pricing:
- Silver rank characters: ¥3,000 (~$20)
- Gold rank characters: ¥20,000 (~$130)
- Diamond rank characters: ¥500,000 (~$3,230)
All five Changokushi mobile NFT games on iOS and Android will shut down on January 15, 2026. After holding an NFT character buyback session on January 22 – February 25, 2026, Okakichi will also shut down the KUSOGeeeeee platform on March 16, 2026.
