Sony Bank has founded BlockBloom Inc., a wholly owned subsidiary that develops Web3 services such as digital assets, NFTs and blockchain infrastructure. The move, released Thursday, follows plans disclosed in July.
The subsidiaries operate under Japan’s regulated framework for digital assets and plan to integrate blockchain technology into banking services. Sony Bank hopes the move will limit the short-term financial impact.
Individual entities focus on blockchain initiatives
Sony Bank, a medium-sized digital first bank under the Sony Financial Group in Japan, has created BlockBloom Inc. to manage Digital Asset Management, NFT Projects, and Blockchain Infrastructure. Subsidiaries will enable banks to develop Web3 services securely. Compliance requirements and operational risks remain separate from core banking activities. Analysts point out that forming dedicated entities is a common strategy among financial institutions entering the regulated digital asset market.
Plans for the Web3 subsidiary came out in July 2025. The bank proposed to provide digital wallets for crypto and NFTS, facilitating the conversion of yen to digital assets. BlockBloom receives $2 million in initial capital and is expected to launch in fall 2025. By establishing a formal subsidiary, Sony Bank has created a structure to advance blockchain-based products without directly affecting traditional banking operations.
Sony Bank expects BlockBloom to have little impact on revenue. This applies to both consolidated and non-consolidated figures for the fiscal year ending March 31, 2026. Japanese regulators have updated their rules for digital assets. Banks can now provide tokenized securities, NFT services and blockchain payments within a regulated framework. BlockBloom operates under these regulations and provides blockchain solutions that are integrated with standard financial services.
Japan’s digital asset market is steadily growing. NFT trading volume has reached billions of yen, and cryptocurrency retail adoption continues to increase. Banks and fintech companies are exploring blockchains for tokenized securities, cross-border payments and smart contract-based lending. For example, several financial institutions have tried to settle blockchain with Digital Yen’s tokenized bonds.
BlockBloom may develop services such as NFT Custody, Tokenized Financial Instruments, and Blockchain Settlement Networks. Subsidiaries can work with Fintech startups. The goal is to create interoperable solutions for digital wallets, NFT markets and decentralized finance platforms.
Impact on the Japanese banking sector
The creation of BlockBloom reflects the measured approach by Japanese banks entering the Web3 space. Our dedicated subsidiary will safely enable Sony Bank Test blockchain products. Evaluate user recruitment and manage regulatory requirements without affecting core operations. BlockBloom can work with Fintech Partners using Sony Bank’s technology and banking expertise. Subsidiaries may contribute to the growth of Japan’s digital finance ecosystem.
Sony Bank’s post excludes its Web3 subsidiary and deepens its digital asset services was first introduced in Beincrypto.
