BTCBOX exchange profile

BTCBOX’s 29 September notice scheduled Bitcoin exchange trading, simple buy/sell, recurring purchases, BTC withdrawals and new account opening to restart on 30 September 2026 at 10:00. This followed a prolonged service interruption. The restart did not restore every facility: market orders and API use remain suspended, and crypto withdrawal destinations remain restricted.[2]

A separate notice restarted BCH/LTC/ETH order-book trading on 21 September, together with ETH simple buy/sell and ETH withdrawals. These dated notices take precedence over older tutorials that still describe market orders or unrestricted transfers. The profile treats BTCBOX as operating with those limits, rather than assuming its historical feature set is fully available.[3]

The current restriction notice limits accepted order prices to within 5% above or below market and says orders outstanding before the shutdown were cancelled. Limit orders remain available within that band. It gives no date for restoring market orders or API service; an old API document or order screenshot is not evidence of current availability.[4]

An unexecuted order can be cancelled through the order list’s change/cancel control. Inspect the result and any already executed portion before placing a replacement; cancellation of a remaining instruction does not reverse a completed trade.[40]

A hypothetical ¥1,000,000 BTC fill costs ¥500 equivalent before spread/withdrawal. Actual fee denomination follows the traded cryptoasset/yen tariff.[9]

Outgoing crypto is currently limited to Japanese exchanges to which BTCBOX can send the required Travel Rule notice. The September restart notice explicitly postpones self-hosted-wallet and overseas-exchange withdrawals until a later announcement. This narrower current rule overrides the broader possibilities still described in its general Travel Rule guide.[2]

The statutory precontract disclosure says customer yen is segregated through a deposit trust account at JSF Trust and Banking. This is a trust arrangement described for client money; it should not be recast as a personal bank account or a universal government guarantee for every crypto balance.[10]

Crypto withdrawals are approved after checks that can require further questions or documents. The storage policy allows refusal where the operator identifies suspicious activity. Accordingly, successful account login or a displayed balance does not by itself establish that a requested withdrawal will be immediately approved.[21]

The terms exclude US residents/locations and specified noncooperative or otherwise prohibited jurisdictions, including places where holding a Japanese bank account is impermissible. An overseas user should therefore establish both account eligibility and a usable withdrawal route before treating verification as complete.[29]

Passkey setup is mandatory after two-factor authentication. Registering an initial/additional passkey or deleting one imposes a 24-hour yen/crypto withdrawal restriction. The guide allows up to ten keys and says each device needs its own registration; enabling passkeys disables password login. Those holds can matter immediately after changing a device.[19]

The support form replies about account matters only to the registered email address. A callback can be requested in the message; the current form gives weekday callback hours of 10:00–17:30. This is a support arrangement, not a documented telephone execution facility.[39]

If no registered passkey device is available, request passkey removal through the contact form. A customer with two or more keys can remove one in settings, while the final remaining key cannot be deleted there. Removal itself triggers the 24-hour transfer restriction; the recovery guide does not promise an instant identity-check turnaround.[20]

The complaint rules route matters through the company’s compliance process and describe external help through the industry association and mediation/arbitration at the Tokyo, Dai-Ichi Tokyo and Daini Tokyo bar associations. The inspected policy does not publish a fixed final-response deadline. Keep the transaction time, order/transfer identifiers and supporting records with the complaint.[28]

The Financial Services Agency register dated 30 September 2026 lists BTCボックス株式会社, corporate number 7020001104824, as a registered cryptoasset exchange provider under Kanto Local Finance Bureau number 00008, registered on 29 September 2017. The entry lists BTC, BCH, ETH, LTC, DOT, DOGE and TRX. This verifies the named Japanese registration; it is not a guarantee of market value, unrestricted withdrawals or permission to serve every country.[30]

The service terms permit correction or cancellation of executions at an abnormal rate attributed to a system problem. A displayed execution can therefore remain subject to the contract’s error-handling provisions. The current restart controls add operational constraints without changing the identity of the contracting company.[29]

The company profile identifies BTCボックス株式会社, using the English name BtcBox co.,Ltd., established on 6 March 2014 and based in Tokyo’s Nihonbashi-Kayabacho district. It describes the exchange’s launch in April 2014 and a parent-company restructuring in 2019. Its historical volume milestones do not establish current active-trader numbers or present liquidity after the 2026 interruption.[31]

BTCBOX offers desktop web, mobile web and an app. The September 2026 app guide permits app registration only for adults resident in Japan; overseas applicants, companies and minors are directed to mobile or desktop web. Availability of a feature in an older app tutorial does not override the current market-order/API suspension.[26]

The API manual describes public market data and authenticated balance/order methods with method-specific rate limits. The current restriction notice suspends API use. Those legacy method descriptions should not be treated as a presently usable automation or withdrawal route, and this profile does not assume that an undocumented partial API service is available.[37]

The documented Bitcoin loan service was suspended on 20 February 2025 for a system upgrade. Its older leverage/loan terms remain online, but a current resumption of that service was not established. It is therefore excluded from the active services described here.[38]
