Tenkura is an independent software studio founded on a single conviction: software should be something you own, not something you rent.
In Japanese, Ten (天) represents the sky—vast, open, weightless, and clear. Kura (蔵) refers to the traditional earthen, fireproof storehouses historically built across Japan to safeguard a family’s most sacred heirlooms, grain, and treasures from fire and disaster.
We merged these two concepts into Tenkura (天蔵). Modern digital life requires both: the fluid, weightless freedom of the sky (seamless streaming, wireless local networks, instant intelligence) combined with the impenetrable, sovereign protection of a private stone vault (your data, your hard drives, your privacy).
Your music library, your family conversational models, and your local sports sessions remain yours. We build software that connects directly to storage you own—rejecting subscription lock-in, rented catalogs, and advertising surveillance.
Rooted in the Japanese concept of Ma (間)—the intentional negative space that gives meaning to the whole. If a feature or visual element generates cognitive noise or serves an advertiser rather than the user, it is subtracted.
We prioritize technologies that survive decades: local Go binaries, embedded SQLite databases, standard OpenSubsonic audio protocols, and self-hosted AI models. If our cloud servers were to vanish tomorrow, your software will still work.
Our craft is expressed through our tools:
