KlimaDAO JAPAN

What KlimaDAO JAPAN does

KlimaDAO JAPAN Co., Ltd. (KlimaDAO JAPAN株式会社) is a Tokyo-headquartered Web3/blockchain company founded in October 2023 by Representative Director Shohei Hamada as the Japan-based operating entity of the global KlimaDAO climate DAO. The company develops and operates CarbonMall (branded KlimaDAO JAPAN MARKET), a digital carbon credit marketplace that runs on the Polygon public blockchain using Carbonmark API smart contracts to tokenize, trade, and retire carbon credits. Its signature technical contribution is the tokenization of Japan's government-operated J-Credits as ERC-20 tokens, the first such implementation on a public blockchain, enabling borderless trading of Japanese-issued credits.

The company serves Japanese enterprises, local governments, and municipalities seeking carbon credit procurement, tokenization, and ESG reporting solutions, with named customers spanning logistics (Yoshida Transport), energy/RPF fuels (Marusanai, Eneriss), forestry (Okayama Forest Management Council, Ishikawa Prefecture, Kiso Sansen), agriculture (paddy farmers), and decarbonization services. Revenue is generated via transaction fees on CarbonMall (commission deducted from seller proceeds on monthly settlement) and consulting fees through the Klima Research Institute (KRI), which offers spot consulting, systems development, advisory support, and trend research with a free initial 60-minute consultation. Additional product lines include the tancre NFT-based individual carbon credit service used at events such as 2024 ZERO CARBON DAY, and the Kurima News weekly ReFi/carbon market newsletter co-published with ReFi Japan.

The go-to-market combines enterprise direct sales (KRI consultation, closed POC partnerships with 15 legal entities) with a self-serve online marketplace (CarbonMall). The company has assembled a core partnership stack including Mizuho Financial Group, OPTAGE, and PBADAO, and has positioned itself as a policy interlocutor via presentations to Japan's Financial Services Agency and the LDP Blockchain Promotion Parliamentary League. Proof-of-concept results — 2,000t J-credits tokenized and 1,000t actually traded over approximately three months — and the Japan Financial Innovation Award 2025 Excellence Award form the headline commercial and regulatory validation to date.

Expansion highlights6 records

Direct peers

• Carbonmark: KlimaDAO-built retail-facing carbon credit marketplace and API; the API layer is what KlimaDAO JAPAN directly leverages, making this the closest infrastructure peer.
• KlimaDAO (Global): The parent decentralized organization whose Carbonmark API and on-chain infrastructure KlimaDAO JAPAN extends into the Japanese market. Most directly comparable as the source technology and governance model.
• Toucan Protocol: One of the largest on-chain carbon credit bridging and tokenization protocols; competes head-on with KlimaDAO globally for tokenized carbon liquidity and registry connectivity.
• AirCarbon Exchange: Singapore-based exchange for voluntary and compliance carbon credits with an Asia footprint; comparable as a regional trading venue targeting corporates in the same buyer pool as KlimaDAO JAPAN.
• Flowcarbon: Tokenizes verified carbon credits and operates a women-led on-chain carbon infrastructure stack; comparable in focusing on bringing high-quality voluntary credits onto blockchain rails.

Others

• Verra (VCS Registry): Operator of the world's largest voluntary carbon credit registry (VCS). Comparable because registry infrastructure is the upstream dependency KlimaDAO JAPAN's tokenization bridges into, and a potential competitor if it moves on-chain.

Regional players

• Tokyo Carbon Exchange (TCX): Japan-focused carbon credit exchange; directly comparable as the closest traditional-market competitor to CarbonMall within the Japanese market.

Emerging players

• Patch (now called Lula): API-driven carbon credit infrastructure that lets developers embed offsetting into products; comparable as a developer-focused carbon-credit API/distribution layer targeting corporates.
• Moss.Earth: Issues tokenized nature-based carbon credits (notably Amazon rainforest conservation) on blockchain; comparable as a tokenization-first climate-finance platform with a global corporate buyer base.

Broad incumbents

• Pachama: AI-driven carbon credit marketplace and MRV technology provider; comparable as a digital infrastructure layer between project developers and corporate buyers, though focused on AI/verification rather than tokenization.
