bitbank exchange profile: services, fees, custody and access

bitbank is a Japanese crypto exchange with an order book, a separate quoted-price purchase service and financed spot trading. The distinctions affect execution, charges and access to balances. This profile covers the business operated by ビットバンク株式会社 (Bitbank, Inc.); its Japanese exchange registration and rules do not create an international retail service.[1][23]

The pre-contract disclosure lists limit, market, stop-limit and stop-market instructions. It also describes circuit breakers that pause matching around specified price movements. Orders and cancellations can still be submitted during the interruption, while the corresponding purchase-desk pair stops accepting orders during its auction period. A stop instruction therefore belongs to a defined execution process; it does not promise a particular exit price. System load may restrict order submission.[3]

BTC/JPY changed on 2 February 2026: its former negative maker commission ended. The revised 0% maker and 0.10% taker tariff applies to both exchange spot and margin transactions. The same announcement left other pairs unchanged. It should not be replaced by the older blanket −0.02%/0.12% headline sometimes associated with bitbank.[5]

Yen deposits use the individual bank details shown in the account and must come from the customer’s own name. The guide distinguishes GMO Aozora and Docomo SMTB routes: the latter uses a nine-character deposit identifier before the sender name. Missing identifiers can delay allocation. Bank transfer costs remain with the sender, and credits depend on the receiving bank and its processing hours.[10]

The user agreement permits withdrawal restrictions after authentication settings are removed or identity information changes, with duration set according to risk and further identity checks potentially required. Large requests, concentrated demand or network changes can also delay or suspend transfers. Before voluntary closure, assets must be withdrawn and needed history retained: after closure, the agreement says transaction-history viewing and transfers become unavailable and the account cannot be restored.[15]

bitbank describes a custodial arrangement. Its security policy separates fully offline multisignature cold wallets from hot wallets using distributed key management. Multiple people sign offline transfers before a signed transaction is moved to a connected environment.[13]

The current age FAQ permits applications from 18 and does not exclude applicants solely for being 75 or older.[17]

Margin applications require age 20 and a separate suitability review. Age eligibility for spot access therefore does not establish approval for financed trading.[6]

Formal complaints go through the CX department, which works with compliance and escalates significant matters internally. The published complaint-policy hours are 10:00–19:00 JST Monday–Friday excluding holidays/year-end. A support request should identify the affected transaction and evidence; it is not documented as a telephone execution instruction.[18]

JVCEA explains that customers apply directly to the Tokyo, Dai-Ichi Tokyo or Daini Tokyo bar centres; sending documents to JVCEA itself does not lodge an ADR application. The route covers disagreement with a member’s response, a direct wish to use ADR, or an unresolved complaint after three months. JVCEA bears the stated JPY 10,000 application fee and the customer’s JPY 5,000 hearing fee, both quoted before tax; settlement fees can remain and allocation is agreed or determined. This is dispute resolution, not automatic compensation.[20]

The FSA register dated 30 September 2026 lists ビットバンク株式会社 under Kanto Local Finance Bureau No. 00004, originally registered 29 September 2017, with corporation number 1010801024625. This establishes the Japanese cryptoasset-exchange registration. The register expressly distinguishes listing an asset from guaranteeing or recommending its value.[22]

The company also discloses Tokyo moneylender registration No. 31821, with the current stated term 29 September 2026–28 September 2029. That relates to its lending business; it should not be read as an overseas derivatives permission. The inspected company disclosure, rather than a separately matched Tokyo register entry, supports that additional registration statement here.[23]

Bitbank, Inc. was established on 7 May 2014. SBI Holdings confirmed completion of the full acquisition on 1 October 2026 after bitbank repurchased shares from MIXI and Ceres. The completion announcement gives capital including capital reserve of JPY 8.05 billion. The business remains Bitbank, Inc.; this ownership event alone does not demonstrate a transfer of customer accounts to SBI VC Trade or a replacement tariff.[24]

For example, if the service actually receives 1 ETH of rewards, retains 30% and a customer represents 1% of eligible aggregate balances, the formula yields 0.007 ETH before precision rounding. The input is an assumed received reward, not a promised annual yield.[27]

Recurring purchases use the desk quotation at the chosen execution moment. A monthly date missing from a particular month moves to its final day; users cannot choose the hour. Insufficient yen or system interruption can skip a purchase until the next scheduled date. This is a purchase instruction, with a different price mechanism from a resting order-book bid.[29]

The documented private API can query balances and histories, submit/cancel orders and request withdrawals after signed authentication. Standard per-user limits are 10 query requests and 6 update requests per second, with a separate system-wide limit and HTTP 429 responses. Key access can therefore reach beyond read-only research. The API documentation provides active-order and exchange-status queries for reconciliation.[30]
