## About

Based in Minato, Tokyo, Japan and founded in, 2023, as Kaguoku Inc., Carbonlink Inc. provides carbon credit trading and brokerage services for Japan's compliance carbon markets. The company originally operated as a real estate technology provider offering an AI-powered home-staging tool ("Kaguoku AI"), before pivoting toward carbon markets, launching its J-Credit Buyback Center in August 2025. As of August 2026, the company is being led by its Representative Director, Daichi Masuyama.
The company operates as a carbon credit trading and brokerage firm, connecting corporate buyers with sellers of carbon credits and emissions allowances. It offers a procurement platform that allows companies to purchase credits from its inventory to offset their carbon footprint, managing the process from purchase through registry retirement and reporting on the client's behalf. It also operates a direct buyback service that purchases carbon credits from holders, giving the company its own steady sourcing channel, and a trading platform for intermediaries to match buy and sell orders for credits, acting as counterparty to keep transactions efficient and confidential. In addition, the company publishes research and market commentary on carbon credit pricing and regulatory developments, and separately offers a home-staging tool for the real estate sector as part of a legacy business line. The offerings primarily benefit corporates seeking to meet decarbonization or compliance targets, as well as credit holders and brokerage intermediaries operating in Japan's carbon markets.
