About this case study
We delivered AI training and ongoing hands-on support to Arth.Japan, a lodging business on Sado Island led by CEO Yuichiro Kamata, the youngest Airbnb Community Leader in the Hokuriku region. Working from in-person hearings, we moved through the real work together: digitizing handwritten documents, converting operations manuals from paper to digital, and building chatbots.
After the training, Arth.Japan signed a one-year follow-up contract. We visit Sado every month to help AI use take root.
