About Ninja Tattoo Dojo
Ninja Tattoo Dojo is a browser shooter where the target is a kanji character and the weapon is a shuriken. You aim and throw, and each hit lands on the symbol and turns into a tattoo of dubious wisdom. The setup is a dojo, and the goal is to keep your throws accurate.
The game takes its tone from the over-the-top mini-games in the Yakuza series, where a silly premise gets played completely straight. That deadpan approach carries through the whole concept, pairing precise ninja action with the idea of permanent body art that probably should not exist. The creator also cites a fondness for odd kanji tattoos as a driver of the idea.
It was built with Three.js and entered in Vibe Jam 2026. The creator's statement names Codex as the tool used to make it. It is designed to work on mobile as well as desktop browsers.
