How to open an account

Source: official guide ↗

1. 1

   Choose nationality, register email and password

   In the signup form on the website or app, choose your nationality, enter your email and a password, and accept the terms.

   1. You must live in Japan, be aged 18 to 74, and have Japan as your only tax residence. People with US tax obligations and foreign PEPs can't apply.
   2. Open the 「口座開設」 (open an account) form on the website or in the app and choose your nationality as shown on your ID.
   3. Enter your email address and a password, then read and accept the terms.
   4. If a foreign national picks 「Japan」 as nationality, BitTrade sends a follow-up email and the application is delayed.

   Tip Pick the nationality on your ID. If a foreign national picks "Japan", BitTrade sends a follow-up email and the application slows down.
2. 2

   Security check and email verification

   Complete the on-screen security check, then enter the "new registration" code sent to your email.

   1. Complete the security check as instructed on screen. If it doesn't work, switch methods with 「認証方法の切り替え」.
   2. Enter the 「新規登録-認証コード」 (registration code) sent to your email and press 「新規登録」 (register).
   3. If the email doesn't arrive, check your spam folder and allow mail from @bittrade.co.jp.

   Tip If it doesn't arrive, check your spam folder and allow mail from @bittrade.co.jp.
3. 3

   Choose an ID check method

   Choose "Myna-ninsho" (Japanese nationals, My Number card, app), the "Kantan" ID check (photograph one of: driver's licence, My Number card, residence card or special permanent resident certificate on your phone) or postcard verification (upload two documents, then receive a postcard).

   1. Choose a method on the 「本人確認」 (ID check) page. Japanese nationals with a My Number card are recommended 「マイナ認証」 (Myna-ninsho): the IC chip is read, with no PIN entry, no document photos and nothing by post.
   2. 「かんたん本人認証」 (Kantan): photograph one of a driver's licence, residence card, special permanent resident certificate or My Number card live, plus a face photo and a short video. The account can open the same day at the earliest, with nothing by post. It's smartphone-only (Safari on iOS, Chrome on Android recommended), not for PCs or tablets, and doesn't accept driving history certificates.
   3. 「本人認証（ハガキ受取）」 (postcard): upload images of two documents, then enter the code from a postcard sent by non-forwardable mail after the review. Accepted: driver's licence, My Number card (front only), health insurance eligibility certificate, Japanese passport (only versions with the holder's address page) and residence card or special permanent resident certificate.
   4. Foreign nationals must submit a residence card or special permanent resident certificate whichever method they choose.

   Tip With Japanese nationality, a My Number card and an NFC phone, Myna-ninsho is the easiest: no PIN, no document photos and nothing by post.

   Enter your details

   Enter your name (also in the Latin alphabet), landline and mobile numbers, occupation, income, main source of income, financial assets, purpose and experience, then tick the declarations.

   1. Enter your name, and your name in the Latin alphabet, exactly as on your ID and bank account.
   2. Fill in both the phone and mobile phone fields; if you have only one number, enter it in both. Double-check the number of digits, a common mistake.
   3. Enter your occupation, pre-tax annual income, main source of income, financial assets, purpose and trading experience. Income means your own income: even if you choose homemaker or not employed, give your own figure, not the household's. If you have a part-time job, choose 「パート／アルバイト」.
   4. Choose your real years of experience. Applications where occupation and income, or age and experience, don't fit together are often sent back.
   5. Read the declaration (not a foreign PEP, not a US taxpayer, no links to organised crime, no tax residence outside Japan) and tick 「以下すべて該当しません」 (none of these apply) only if that's true.
   6. With Myna-ninsho the order is reversed: you read the card and take the face photo first, then enter details such as your Latin-alphabet name and phone number.

   Tip Write your name exactly as on your ID and bank account. If you only have one phone number, enter it in both fields. See "Application questions explained" below.
5. 5

   Verify with the IC chip or photos

   Myna-ninsho: enter your date of birth, expiry year and security code (auto-filled on iPhone), tap the card on your phone and take a face photo. Kantan: photograph your ID, your face and a short video live. Postcard route: upload images of two documents.

   1. Myna-ninsho: enter your date of birth, expiry year and the card's 4-digit security code (on the front), then tap 「次へ」. On iPhone these fill in automatically; on Android, type them.
   2. Hold the card to the top of an iPhone, or to your Android model's reading spot. No PIN is needed. Then take a face photo.
   3. Kantan: photograph your ID live inside the on-screen frame, then take a face photo and a short video. If you applied on a PC, scan the on-screen QR code with your phone to continue.
   4. Tips: use the original and avoid blur, glare and cropping. Copies and scans aren't accepted. A weak connection can stop the camera frame from appearing.
   5. Postcard route: upload images of two documents (PNG or JPEG, up to 5 MB). Submit only the front of a My Number card, and mask the symbol and number fields on a health insurance eligibility certificate before uploading.

   Tip If you applied on a PC, continue the Kantan check by scanning the on-screen QR code with your phone.

   Review

   With Kantan, review usually takes one business day (same day at best). If something is wrong you get a rejection email: fix it and reapply. On the postcard route, enter the code from the postcard (sent by non-forwardable mail) to finish.

   1. With Kantan, the review usually takes one business day, the same day at the earliest. No typical time is published for Myna-ninsho.
   2. If something doesn't match or needs checking, you get a rejection email. Log in, read the reason, correct it and apply again.
   3. On the postcard route, enter the code from the non-forwardable postcard under 「本人確認」 after logging in. Accounts whose delivery is confirmed may be activated automatically, in which case no code is needed.
   4. When you pass, you're notified by email and can start trading.
7. 7

   Set up 2-step verification

   Set up SMS or Google Authenticator. You need it before you can deposit yen.

   1. 2-step verification is mandatory once the account is open; without it you can't deposit or withdraw yen.
   2. SMS: in the security settings choose 「SMS認証」, enter your phone number, tap 「コードを入手」 (get code), enter the 6 digits you receive, then the codes for the follow-up security check.
   3. Google Authenticator: install it first, then go to 「Google認証」 → 「認証アプリを設定する」 and scan the QR code or paste the secret key. Enter the 6-digit code from the app, tap 「設定」, and confirm with the SMS and email codes.
   4. The secret key (or QR code) is what you use to recover access if you change or lose your phone, so save a copy somewhere safe before you finish.

   Deposit yen and buy

   Quick deposit (docomo SMTB Net Bank, PayPay Bank, AEON Bank, Minna no Ginko) is free and usually lands in about 20 minutes. Bank transfers cost your bank's fee; Pay-easy and convenience-store deposits carry a fee.

   1. In the app, tap 「入金」 (deposit) → 「JPY」 and choose a method such as 「振込入金」 (bank transfer), 「クイック入金」 or 「コンビニ入金」 (convenience store). On a PC: 「資産管理」 → 「入金」 for JPY.
   2. For a bank transfer, pay into your dedicated deposit account. There's no deposit fee (you pay your bank's charge) and no maximum amount.
   3. Quick deposit (docomo SMTB Net Bank, PayPay Bank, AEON Bank, Minna no Ginko) is free and usually lands in about 20 minutes. PayPay Bank's limit is ¥300,000 by default; you change it at PayPay Bank.
   4. Pay-easy and convenience-store deposits carry a fee, and are capped at ¥9,999,999 and ¥300,000 per deposit respectively (fee included, once per 24 hours).
   5. Whatever the method, pay from an account in your own name. Assets equal to Pay-easy, convenience-store or AEON Bank quick deposits can't be withdrawn or sent out for 7 days.
   6. To buy: for coins on the order book, such as BTC, ETH and XRP, use the exchange (orders from ¥2); buy other coins on the sales desk, which has no fee but builds its cost into the buy/sell spread.

   Tip Deposit from an account in your own name. After AEON quick deposits, Pay-easy or convenience-store deposits, an equal amount can't be withdrawn for 7 days.

スムーズに開設するコツ

Tips for a smooth signup

• Japanese nationals should use Myna-ninsho. Have your My Number card, an NFC phone and the latest BitTrade app ready.
• If you're 75 or older, BitTrade isn't an option; consider an exchange with no upper age limit, such as bitbank.
• For coins on the order book (BTC, ETH, XRP and others), the exchange is cheaper. The sales desk charges no fee, but the buy/sell spread is the real cost.
• From 1 Apr 2027, online ID checks that rely only on photos of your ID and face are abolished by law. Having a My Number card ready is the safest bet.
