ID and Cash Limits for Buying Gold in Japan
In Japan, a jeweller or bullion dealer must check your ID when you buy or sell precious metals and the payment is more than ¥2 million in cash (Act on Prevention of Transfer of Criminal Proceeds). There is no legal cap on paying cash. When you sell gold or platinum bars or coins for more than ¥2 million, you give the dealer your name, address and My Number, and the dealer files a payment report (支払調書) with the tax office.

The rules in detail
- Jewellers and precious-metal dealers are covered businesses under the Act on Prevention of Transfer of Criminal Proceeds (犯罪収益移転防止法). They must verify your identity for any sale or purchase of precious metals (gold, platinum, silver and their alloys), gems or products made from them where the price is paid in cash and exceeds ¥2 million.
- If a deal is obviously split to stay under ¥2 million, the parts are added together. Suspected impersonation and some higher-risk customers need checks at any amount, plus checks on assets and income above ¥2 million.
- The dealer keeps an identity record and a transaction record, and files a suspicious transaction report with no minimum amount.
- There is no general limit on paying cash in Japan. Large purchases are usually paid by bank transfer.
- No change to the ¥2 million threshold had been made as of October 2026. The trade ministry (METI) revised its list of suspicious-transaction examples for dealers on 19 June 2026; one example is splitting sales to stay under the payment-report threshold.
When you sell
- Shops buying used goods are secondhand dealers (古物商) and must check your ID and record the deal unless the total is under ¥10,000.
- Since October 2019, dealers must keep a copy of the seller's ID to claim consumption tax credit on gold bullion they buy, so expect an ID check at any amount.
- For gold or platinum bars and coins (e.g. Maple Leaf gold coins) sold for over ¥2 million, you give your name, address and My Number. The dealer reports the payment to the tax office by the end of the following month. Jewellery and silver aren't in this report.
- No tax is withheld; any gain is declared on your own tax return.
Silver and travel
- Silver is covered by the ¥2 million cash ID rule, but not by the bullion payment report.
- At the border, declare cash and other means of payment over ¥1 million, and gold of 90%+ purity weighing over 1 kg.
