Products
Beacon
Inspection in dark places still relies on the human eye in many situations, and an overlooked anomaly or sign of deterioration can lead to an accident. Even where AI could help, the risk of information leaking when images are sent to the cloud stands in the way of adoption.
Beacon is an edge AI system that runs low-light image enhancement and object detection, together with a local LLM, fully offline. The aim is for it to be installed and used on a single existing PC in the field, with no special equipment. At its core are XCR and SD-Retinex, methods I have published.

At the Tongali Business Plan Contest 2026, Beacon received the NICT Award, two Supporter Awards (the JR Central Award and the Beyond Next Ventures Award) and 5th place for the Tongali Award (Toma Okugawa, Uryu Den, Keito Inoshita).
Kyudo AI
Just stand your phone up and shoot. Kyudo AI is a smartphone app that automatically detects kai (the full draw) in kyudo (Japanese archery) and scores the shooting form on the spot. The skeleton is estimated on the device, and the form is scored on four metrics: equidistance and sanju-jumonji (the three crosses: shoulders, hips, feet). Video does not leave the device. Hit records, AI consultation and club messages are also brought together in the same app.
It is currently in development and field trials (before store release). We are looking for schools and dojos willing to take part in the trials.
