# bitFlyer to add 48-hour crypto transfer hold in Japan Author: Hatice Ertaş Language: English Published: 2026-10-03T12:09:44+03:00 Updated: 2026-10-03T12:53:42+03:00 ![Hourglass in a mechanical assembly bearing the bitFlyer name and yen symbol](https://kriptometa.com/uploads/bitflyer-den-kripto-transferlerine-saatlik-bekleme-d5788dacef4c_article.webp) ## Key takeaways - The Japan policy starts on October 15 and does not cover every customer or the whole account balance. - The crypto equivalent of yen deposited in the past 48 hours above JPY 100,000 will be restricted from external transfers. - Crypto trading and yen transactions remain available; Quick Deposit retains its separate seven-day transfer restriction. bitFlyer is introducing a partial hold on crypto transfers after yen deposits to help combat fraud. It will apply to individual customers who completed identity verification less than 90 days earlier. Japanese [crypto exchange](https://kriptometa.com/en/reviews/exchanges) bitFlyer will introduce a partial 48-hour hold on outbound crypto transfers from October 15 to help combat fraud. The policy applies after yen deposits by individual customers who completed [identity verification](https://kriptometa.com/en/glossary/kyc-aml) less than 90 days earlier. Of the total yen deposited in the preceding 48 hours, the first JPY 100,000 will remain outside this restriction. The company’s [October 2 announcement](https://prtimes.jp/main/html/rd/p/000000151.000047991.html) concerns yen deposits in Japan. Eligibility is based on when identity verification was completed, rather than when the account was opened. Existing account holders will therefore also be covered if they are still within that 90-day period when the policy begins. ## How the JPY 100,000 threshold works The calculation in bitFlyer’s [English-language notice](https://bitflyer.com/pub/20261002-introducing-cooldown-for-crypto-transfers-en.pdf) uses the aggregate yen deposited over the past 48 hours, excluding fees. JPY 100,000 is subtracted from that total; the crypto equivalent of the remainder cannot be sent out. If deposits in that window total JPY 300,000, for example, the restricted amount would be the equivalent of JPY 200,000. This illustrates the announced formula, rather than the available balance of any particular account. **JPY 100,000 is not a separate transfer allowance for each deposit.** The rule uses the combined total over 48 hours. Where there are multiple deposits, the restriction eases as each deposit’s own 48-hour period expires. Customers will not need to apply for the change. The available transfer amount will appear on the app and website’s crypto-send screens. Yen deposit details will also show when the cooldown ends. Actual holdings and other existing restrictions can separately affect how much a customer is able to send. ## Trading continues while external transfers wait The policy does not freeze every account function. Yen deposits and withdrawals, crypto purchases and sales, and receiving or holding crypto remain unaffected by this measure. It restricts external transfers of the crypto value associated with qualifying yen deposits. This is also distinct from [waiting for a transaction to receive blockchain confirmations](https://kriptometa.com/en/track-crypto-transaction): the exchange applies the restriction before the transfer goes out. Quick Deposit is treated separately. It already carries a seven-day transfer restriction and is excluded from the new calculation. That exemption therefore does not let Quick Deposit users immediately send the crypto elsewhere. Customers cease to fall within the new policy’s scope once 90 days have elapsed since identity verification. ## A separate warning about fake bitFlyer calls In a [fraud warning posted the same day](https://x.com/bitFlyer/status/2105825091783389446), the exchange described people impersonating bitFlyer staff. The reported approach involves claiming an account has been accessed without permission, trying to direct the recipient through actions by phone, or seeking login information through links in texts and emails. The hold is intended to create time before assets leave the exchange in scams such as these [phishing attempts](https://kriptometa.com/en/glossary/phishing). > “bitFlyer will never ask you to send crypto.” From the company’s English-language notice dated October 2.
