On May 7, 2026, the Japan Cryptocurrency Business Association (JCBA), chaired by Noriyuki Hirosue, published best practices guidance for cryptocurrency staking businesses. The guidance was developed by the JCBA's Staking Committee, chaired by Eisuke Watanabe, and is intended to serve as a reference for staking service providers and related industry participants. The best practices address the expanding domestic and international staking market by emphasising safety, transparency, and user protection. The guidance recognises that while staking-related services have expanded in Japan following the adoption of Proof-of-Stake (PoS) and related models, risk management approaches, information disclosure practices, and user communication methods vary significantly across service providers. The best practices framework covers key operational areas including staking service classifications, primary staking risks, operational requirements and emergency response procedures, information disclosure and accountability, compliance, external audits, and tax and accounting considerations. The guidance is non-binding and is positioned as a reference framework for operators to inform business decisions and service improvements, rather than as regulatory or enforceable requirements. The JCBA Staking Committee intends to use publication of the best practices as a catalyst for ongoing dialogue among service providers and to address practical industry challenges. The Committee plans to update the guidance as necessary to support safe and sustainable service provision among JCBA member companies and other domestic and international staking service providers with an interest in the guidance. The best practices document is available for download on the JCBA website.
