About us

Message from the Director

I had a chance to buy BTC and realized its future potential. The more I looked into it, the more interesting it became, and the feeling that this is the next IT revolution is getting stronger day by day. Gartner, a famous research firm, also seems to predict that blockchain will reach maturity and penetrate society in the 2020s.

I would like to contribute to the de-centralized Web society that this technology will make possible, while utilizing my own knowledge and position.
