I explore computer technology that respects and harmonizes with existing nature, human life, and culture. I'm drawn to technology that can seamlessly replace or complement existing systems without disrupting their essence.

Instead of the centralized, hierarchical models prevalent today, I build distributed systems where independent, autonomous agents interact to produce deterministic outcomes. This eliminates unhealthy, rigid master-servant relationships. Furthermore, I believe this enables more flexible and scalable systems that fit naturally within the context of existing nature, life, and culture.

Amida-san is one example of this. It reimagines the traditional amidakuji lottery with cloud technology, where individual participants influence the outcome, ensuring transparency and collective buy-in. It embraces existing culture while implementing a decentralized system without central authority.
