Highlights

  • The Japanese arm of Hong Kong's HashKey Group (renamed from Tokyo Hash on 1 Jun 2026)
  • Large trades of ¥1M–¥50M per order, placed by phone at a price the operator quotes

  • Purchased BTC and ETH are sent straight to your own wallet after each trade; nothing is left on deposit
  • All customer crypto is kept in cold wallets, and yen is held separately in trust at Nisshokin Trust Bank

Limits

WhatLimit
Buying crypto
  • ¥50,000,000 per order ¥1 million to ¥50 million per order (by quantity or by amount). Separately, each customer has a trading limit set from their declared income and assets, which isn't published (ask HashKey Japan). Source
Yen deposits No published limit
Yen withdrawals No published limit
Sending crypto out No published limit

First crypto send-out

Coins aren't kept in an account: each time a purchase is executed, the BTC or ETH is sent to the delivery address you registered in My Page. A trade normally completes the same day, and delivery happens at the latest by the next business day after the trade. No new-account waiting period is published, and HashKey Japan pays the network fee.

Protections against fraud

  • Before each delivery, HashKey Japan assesses the transfer's risk from the recipient details you registered and may refuse it or ask for more information. If details are missing or doubtful, the coins aren't delivered.
  • When the destination is an exchange address, delivery waits until the Travel Rule notice to that exchange is complete, which can take extra time.
  • Under the revised Foreign Exchange Act, HashKey Japan may ask for the purpose of a transfer, sender and recipient details, and supporting documents.
  • Orders from a phone number other than the registered one get an extra identity check, and for large trades you may be asked to show the ID you submitted when opening the account.
  • Transfers to online casino addresses are refused, and trading or the account is suspended if dealings with an online casino come to light.

Transfer rules

Sending to your own (private) wallet
Allowed
What's required (Travel Rule)
For each delivery address you register whether the recipient is you (if not, their name and address), the exchange's name if it's an exchange address, and the purpose. For exchange addresses, HashKey Japan notifies that exchange of sender and recipient details. Your own private wallet can be registered, and the terms make having your own wallet a condition of opening an account.
Destinations you can't send to
Because they use a different notification system, coins can't be delivered to bitFlyer, Coincheck, Crypto Garage or Binance Japan. Since 3 Aug 2026, foreign exchanges in the 63 countries and regions designated by the FSA are excluded too, and transfers to online casino addresses are refused.

How to open an account

  1. 1

    Check the conditions and get ready

    Before applying, check that you meet the age, residence, income and asset conditions, and have your own wallet for receiving coins, two ID documents and a bank account in your name ready.

    1. You must be 20–69 when you apply and live in Japan. Applications from people aged 70 or over aren't accepted.
    2. The account criteria require annual income and financial assets of ¥5 million or more. If your real figures fall short, choose a regular exchange where you can buy small amounts.
    3. Purchased BTC and ETH are sent to your own wallet after each trade, so set up a receiving wallet first (an account at another exchange, a hardware wallet and so on). The terms also require you to have your own wallet.
    4. Prepare two ID documents showing your current address (driver's licence, the photo side of a My Number card, a residence card and so on). Foreign nationals must include a residence card or special permanent resident certificate.
    5. You also need a Japanese bank account in your own name to receive yen.

    Tip Coins can't be delivered to bitFlyer, Coincheck, Crypto Garage or Binance Japan addresses, so pick another destination.

    Upload two ID documents

    Straight from the completion screen, upload images of two ID documents that show your current address.

    1. Examples: driver's licence, My Number card (photo side only), residence card, special permanent resident certificate, or a residence record or seal registration certificate issued within 6 months. Check the full official list.
    2. A Japanese passport counts only if it was applied for by 3 Feb 2020; passports issued by other countries aren't accepted.
    3. If an ID shows an old address, add one supporting document (a utility receipt or tax certificate from the last 6 months, for example).
    4. Make sure the address, name and date of birth are sharp and match your application. Expired documents aren't accepted.
    5. You don't need to submit your My Number; hide the number on any document that shows it.

  5. 5

    After review, enter the code from the registered letter

    Review takes 1–2 business days. The result comes by email; if approved, an 「口座開設手続き完了のご案内」 letter arrives by registered, non-forwardable mail. Enter its identity code in My Page and the account is open.

    1. The result is emailed to you. Reasons for the decision aren't disclosed.
    2. The letter goes by registered, non-forwardable mail to your registered address, and you can't choose a delivery date. If you have mail forwarding set up, cancel it first.
    3. If you're out, follow the missed-delivery slip and collect it before the deadline; if you miss it, ask for redelivery via the contact form.
    4. Log in to My Page with your email (or the 「MyページログインID」 in the letter) and password, then pass 2-step verification by picking the emoji sent to you by email.
    5. Enter the letter's identity code (only once) to finish. Keep the letter: it holds information you need for trading.

    Tip You can't trade until HashKey Japan has confirmed you received the letter.

    Register your receiving wallet address

    In My Page, under 「お客様情報」 → 「出庫先アドレス」, register the address that will receive BTC or ETH, with the Travel Rule recipient details.

    1. Open 「お客様情報」 in My Page's side menu and, under 「出庫先アドレス」 in the middle of the screen, choose the coin(s) to register or change (BTC, ETH or both).
    2. Paste the receiving wallet address exactly. Coins sent to a wrong address may be lost for good.
    3. Say whether the recipient is you; if not, enter the recipient's name and address.
    4. If the address belongs to an exchange, pick its name from the 「業者名称」 list. Domestic exchanges not on the list can't receive deliveries.
    5. Choose the purpose of the transfer and finish.

    Tip If the recipient details are missing or doubtful, the coins won't be delivered.

    Order by phone and pay by bank transfer

    Call on a weekday between 9:00 and 16:00 with your order and you'll get an indicative price and amount. Transfer yen to the designated account; once it's confirmed you get a final price, give the order, and the BTC or ETH is sent to your registered address.

    1. Call 050-3204-4855 from your registered number and give the coin (BTC or ETH), that you're buying, and the quantity or amount (¥1M–¥50M). Calls from another number get an extra identity check.
    2. The operator quotes an indicative price and amount; the price includes a fee-equivalent of 0.1–5.0%.
    3. Transfer from an account in your name to the designated account shown under 「振込入金先情報」 in My Page. For a quantity order, send a little extra in case the price moves. Transfers from someone else's account aren't accepted.
    4. When the money is confirmed, HashKey Japan contacts you, checks the order and quotes a final price. If you accept, give the order there and then; it's executed and can't be changed or cancelled afterwards.
    5. The coins go to your registered address, usually the same day and at the latest by the next business day after the trade; unused yen is returned to your bank account by the next bank business day.

    Tip If the money can't be confirmed within business hours, it's handled the next business day; if you don't place the order that day, it's treated as cancelled and returned.

Application questions explained

What each question means and how to answer it accurately. Always answer truthfully. Answers that don't match reality lead to rejection or a frozen account.

Occupation
What it means
Used for identity checks and to judge whether your trading matches your circumstances.
How to answer
Give your current occupation honestly, choosing whatever is closest to your real position, such as company executive or self-employed.
Annual income (pre-tax)
What it means
Used to check the account criteria (income and financial assets of ¥5 million or more) and to set your personal trading limit.
How to answer
Declare your approximate pre-tax income honestly. Don't overstate it to meet the condition: the account criteria state that a false declaration can lead to trading being stopped or the account closed. If you don't meet the condition, choose a regular exchange instead.
Financial assets
What it means
Total savings, stocks, funds and similar. Like income, it's used for the account criteria and your trading limit. Real estate is normally not included.
How to answer
Declare the approximate total in your own name honestly (not your family's).
Bank account for payouts
What it means
Where sale proceeds and any yen not used for a purchase are paid.
How to answer
Register a Japanese bank account in your own name; accounts in anyone else's name, including family, can't be used.

Official explanation

Confirmation that you are not a US taxpayer or a foreign PEP
What it means
The account criteria exclude US taxpayers and foreign PEPs (senior foreign public officials, their families and the like).
How to answer
Answer truthfully. If you have US tax obligations or are a foreign PEP, you can't open an account at HashKey Japan.

Official explanation

Recipient details for your delivery address (Travel Rule)
What it means
Required by law before any delivery: whether the recipient is you, the receiving business's name and the purpose. For exchange addresses, the details are passed to that exchange.
How to answer
For your own wallet, choose yourself as the recipient; for an exchange address, choose its name from the list. Pick your real purpose. Inaccurate details mean the coins won't be delivered.

Official explanation

Tips for a smooth signup

  • Have your receiving wallet ready before you apply; you can't receive BTC or ETH until the address is registered in My Page.
  • Deposits are checked within business hours, so on trading day transfer the money with time to spare.
  • If you want to start small or don't meet the income and asset conditions, a regular exchange where you can buy small amounts suits you better.
  • Applications are accepted only up to age 69. If you're 70 or older, consider exchanges with no upper age limit, such as bitFlyer, bitbank or GMO Coin.
  • Before registering an address, check that HashKey Japan can deliver there (not to bitFlyer, Coincheck and a few others). Coins sent to a wrong address can't be recovered.
