Do other countries make companies report their bitcoin, and what are the rules?
Research question: Do national governments other than the United States require companies that hold bitcoin to report it, and what disclosure rules apply?
The records show that Japanese listed companies report material events, including bitcoin purchases, through the TDnet (Timely Disclosure network) 8. Japan's 2026 amendment moves crypto-asset regulation into the Financial Instruments and Exchange Act, but the records do not say it imposes bitcoin-holding reporting duties on companies 1. The other facts mostly concern crypto-asset firms rather than corporate holders: Germany requires BaFin authorization, client identification, and suspicious-transaction filing 642, the EU adopted the Markets in Crypto-Assets Regulation 3, and the UK adopted the Financial Services and Markets Act 2023 5. The newest fact is dated October 7, 2026 8, so it is current, but the evidence only partly answers whether non-US governments require companies holding bitcoin to report it.
