How to open an account

Source: official guide ↗

1. 1

   Create an account

   Under "Create account" on the official site, enter your email and a password and agree to the terms of use, the pre-contract document and the privacy policy. After a security check, enter the code from the email to finish.

   1. Check the conditions first: aged 18–74 when applying, living in Japan, not a US taxpayer or citizen, not a foreign PEP, not investing borrowed money, and an email and mobile number that no other customer uses. Residence-card holders who don't work at an office in Japan must have been in Japan for 6+ months.
   2. On S.BLOX's website (www.sblox.jp) press 「アカウント登録」 and enter your email and a password (you can change the password after logging in).
   3. Open and read 「利用規約」, 「契約締結前交付書面(現物等)」 and 「プライバシーポリシー」, tick to agree and press 「アカウント登録」.
   4. Complete the security check as shown on screen and press 「確認」.
   5. On the email verification screen, enter the code sent to your address; that completes the account. If it hasn't arrived, check your spam folder.

   Tip Check your spam folder too.

   Set up SMS verification

   Before the ID check, set up SMS verification with your mobile number: in the app under Settings > SMS verification, or in a browser under My Page > Security.

   1. SMS verification must be set up before you can apply for the ID check, and this phone will also receive codes for every later send and withdrawal.
   2. In the app: from the menu after login open 「各種設定」 → 「SMS認証」, press the 「ON/OFF」 button and enter a mobile number that can receive SMS.
   3. In a browser: open 「マイページ」 (top right) → 「セキュリティ」 in the left menu (on a phone browser, 「≡」 → 「セキュリティ」), press 「設定」 next to 「SMS認証」 and enter the number.
   4. Press 「送信する」 in the code field, enter the code you receive and press 「送信」. The countdown shows when you can request it again. If nothing arrives, check the number you entered.
   5. When the number appears, partly masked, under 「SMS認証」, the setup is done.

   Tip You need your own mobile number that isn't used on anyone else's account.

   Enter your details

   On the identity verification screen (My Page in a browser, or via your user ID at the top of the app menu), enter your name, address and other basics and accept the declarations. Then fill in your occupation, assets and trading experience.

   1. Open the ID verification screen: in the app, the 「＞」 next to your user ID at the top of the menu → 「本人確認のステータス」; in a browser, 「マイページ」 → 「本人確認」 (phone browser: 「≡」 → 「本人確認」). The application has three screens; each saves when you press 「次へ」, so you can stop and pick up later.
   2. On 「お客様情報の入力」 enter nationality/region, your name (family name, optional middle name, given name), katakana, romaji, date of birth, and postal code, prefecture, city, street and building. Use your real name as on your ID (not a former surname) and your current address exactly as on the ID. Fill in 通称名 only if your ID shows one.
   3. Under the declarations, tick 「以下全てに該当しません」 only after reading the list (overseas resident; under 18 or 75+; working for a crypto exchange; no investment experience and no grasp of how crypto trading works; investing borrowed money; US citizen, green-card holder or US resident; foreign PEP; US taxpayer; organised crime and more) and only if truly none applies.
   4. Declare your tax residence country (CARF), tick the agreement to the listed terms and 「私は以上の書類の内容を理解、同意したうえで本人確認を申請します。」, then press 「次へ」.
   5. On 「お取引に関する情報」 enter the purpose of trading, occupation, pre-tax annual income in units of ¥10,000 (type 300 for ¥3 million), the 取引限度額 figure, total financial assets and how you found S.BLOX, then tick your investment experience (FX, stocks, CFDs, futures and so on; several allowed). If a field is unclear, ask through the contact form rather than guess.
   6. Choosing no investment experience is allowed, but you must still understand how crypto trading works and its rules. Answer every item truthfully.

   Tip Your name and address must match your ID document. If the address on it differs from where you live now, the account can't be opened.

   Photograph your ID and face with "Kantan" ID check

   Choose "Kantan ID check" and continue on your phone via the QR code or the emailed link. Photograph one of: driver's licence, My Number card, passport, driving history certificate or residence card — front, held in your hand, then back — and take a face photo, moving your face as instructed.

   1. On 「本人確認書類の提出」 choose 「かんたん本人確認」 as the submission method. It's for individuals only and unavailable during maintenance from 3:00 to 6:00 on the second Thursday of each month.
   2. Continue in a camera-equipped smartphone's browser via the QR code shown or the link in the email S.BLOX sends. Even if you applied on a PC or tablet, the submission is done after logging in on a phone.
   3. Use one of: driver's licence, My Number card, passport, driving history certificate, or residence card (foreign nationals). The capture runs on LIQUID eKYC from Liquid Inc., S.BLOX's contractor.
   4. Photograph the front of the document, the document held in your hand, then the back; then take a face photo and turn your face up, down, left and right as instructed.
   5. Tap 「次へ」 on the 「撮影完了」 screen; 「申込完了」 means the submission is done.
   6. Switching to the postcard route part-way discards everything entered for the Kantan check, so decide on the method before you start.

   Tip Even if you applied on a PC or tablet, the photos are taken in a camera-equipped smartphone's browser.

   If you choose the postal ID check

   With the postcard route, upload two ID documents (or one plus a supporting document). After review a non-forwardable postcard arrives; enter its account opening code on the identity verification screen to finish.

   1. The postcard route is for people who'd rather receive mail at home, and for foreign nationals whose only document is a special permanent resident certificate.
   2. Upload two ID documents, or one plus a supporting document: a residence record without the My Number printed, a seal registration certificate, or a water or listed power-company electricity bill in your name showing your current address, all within 3 months. Foreign nationals put the residence card or special permanent resident certificate first.
   3. Photograph the originals in colour with a phone or camera; scans, photos of copies and edited images are rejected. Avoid shadows, blur, glare, fingers and cropped edges. JPG or PNG, up to 5MB each; both sides are needed for everything except the My Number card.
   4. If your driver's licence or My Number card has the organ-donation section filled in or signed, cover it (by masking the image or with paper or a sticky note) before taking the photo; otherwise it isn't accepted.
   5. On 「入力内容の確認」 check that your name and address exactly match the documents and that they're sharp and unexpired, then press 「申請する」.
   6. After review, mail with your account opening code comes by non-forwardable registered post to your registered address (the post office holds it for 7 days, and it can't go elsewhere). Log in, enter the code on the 「本人確認」 screen and send it to complete the opening.

   Tip Foreign nationals who only have a special permanent resident certificate must use this route.

   Review, then your account opens

   You get the result by email after review. With the Kantan ID check, the account can open as soon as the day after you apply.

   1. S.BLOX reviews your details. With the Kantan check the account can open as soon as the day after you apply, though it can take longer.
   2. The result comes by email. With the Kantan check, that notice completes the opening; no mail is sent.
   3. If something doesn't match or needs extra checking, you'll be emailed; review it, correct the details and reapply.
   4. If the email says extra verification is needed, submit a document showing your income that fits your situation (withholding slip, two months of payslips, income certificate, tax notice, tax return, bank-book images and so on) and reapply.
   5. S.BLOX doesn't disclose its review criteria or the reasons for a decision.

   Tip If something doesn't match or needs checking, you'll get an email; review it and reapply.

   Deposit yen and buy

   Transfer yen to your dedicated account shown on the "JPY deposit" screen, then buy on the sales desk. S.BLOX charges no deposit fee, but you pay your bank's transfer fee.

   1. In the app, tap 「日本円入金」 at the bottom after logging in; on a PC, 「資産管理」 (top right) → 「日本円入金」 in the left menu; in a phone browser, 「日本円入金」 from the top-right menu. Your own dedicated account appears under 「口座情報」.
   2. Read the notes on the screen and transfer from an account in your own name. Transfers in another name aren't credited, and getting the money back needs a recall (組戻し) and a fee. Bank transfer is the only method; S.BLOX charges no deposit fee (your bank's fee applies) and there's no upper limit.
   3. Deposits are usually credited at once, but not instantly from banks outside the Zengin 'more time' system or during bank maintenance.
   4. On the sales desk, pick a coin and buy by quantity or yen amount. Orders are market orders only and can't be changed or cancelled once placed. Minimums start at 0.00001 BTC; there's no trading fee, but prices include a spread.
   5. To withdraw yen later, first register a bank account in your own name. Withdrawals are limited to twice a day, from ¥1,000 each, up to ¥10 million per 24 hours, with a ¥330 fee each.

   Tip Transfers from an account in a different name are not credited. Getting the money back needs a recall (kumimodoshi) through your bank, which costs a fee.

Tips for a smooth signup

• Use the Kantan ID check on your smartphone for the fastest route (account open as soon as the next day). The postcard route needs two ID documents.
• Applications are accepted only up to age 74. If you're 75 or older, consider exchanges with no upper age limit, such as bitFlyer, bitbank or GMO Coin.
• Before sending to another exchange, check that S.BLOX can send there; direct sends to bitFlyer, Coincheck, Binance Japan and some others aren't possible.
• Crypto sends requested by 16:00 on a weekday are usually processed the same day; later or weekend/holiday requests are processed the next business day.
