Setting Up PayPay in Japan: A Complete Guide for Expats

How Popular Is PayPay in Japan?

PayPay is by far the most widely used mobile payment service in the country, run by PayPay Corporation under the SoftBank group. As of August 2026 it reported 75 million registered users, more than 43 million of them fully verified, and upwards of 10 million locations accepting the code — well over a fifth of all cashless payments in Japan.

Why It Is Worth Setting Up

1. Almost everywhere takes it: convenience stores, supermarkets, drugstores, chain restaurants, taxis, rideshare apps, vending machines, and a growing share of small independent shops
2. Bills and taxes: utility bills, NHK receiving fees and local tax payments can all be paid by scanning the barcode in the app
3. Campaigns: PayPay runs point-back campaigns constantly, and the larger events give more back
4. Transfers: verified users can send balance to other PayPay users free of charge

What You Need Before Registering

Step-by-Step Registration

Step 1 — Download the PayPay App

• App Store: Search "PayPay" (developer: PayPay Corporation)
• Google Play: Same
• Open the app and select New User Registration (新規登録)

Step 2 — Enter Your Phone Number

1. Enter your Japanese mobile number — PayPay does not accept overseas numbers, so sort out a Japanese SIM first
2. The system sends an SMS verification code
3. Enter the code

⚠️ Prepaid voice-and-data SIMs and SMS-only numbers can be hit and miss. A standard contract with a Japanese carrier or MVNO (Rakuten Mobile, IIJmio, ahamo and similar) works reliably.

Step 3 — Set a Password

Set a 6-digit login password — used to confirm payments. You can also enable fingerprint or Face ID as an alternative.

Step 4 — Complete Initial Setup

Fill in basic information:

• Date of birth (for age verification)
• Email address

Your account is usable immediately for QR payments, and any money charged in before verification lands in PayPay Money Lite, which cannot be withdrawn to a bank account.

Completing Identity Verification (eKYC)

Verification is what unlocks the useful half of the app: higher spending limits, balance transfers, and the ability to withdraw balance back to a bank account.

Verification Steps

1. Tap Account (アカウント) on the app home screen
2. Select Identity Verification (本人確認)
3. Choose Residence Card (在留カード) as your identity document
4. Follow the prompts to photograph front and back of your Residence Card
5. Take a selfie (the system compares it to your Residence Card photo)
6. Wait for review (typically 1–3 business days)

After approval, the app sends a notification and your account tier is upgraded.

Top-Up Methods for Foreign Nationals

Method 1: Link a Japanese Bank Account (Recommended)

After linking a Japanese bank account, you can transfer directly without manual steps each time.

Supported major banks:

• Japan Post Bank (ゆうちょ銀行) ✅
• MUFG (三菱UFJ) ✅
• Rakuten Bank (楽天銀行) ✅
• Docomo SMTB Net Bank (formerly SBI Sumishin) ✅
• Mizuho Bank (みずほ銀行) ✅
• PayPay Bank ✅

Roughly 1,000 institutions in total are supported, including most regional banks.

How to link:

1. In the app, tap Top Up (チャージ)
2. Select Bank Account (銀行口座)
3. Choose your bank and follow the prompts to complete the link
4. Enter the top-up amount and confirm

Method 2: Cash at a Convenience Store ATM

If you don't have a Japanese bank account yet, you can pay cash straight into PayPay:

1. In the app, select Top Up (チャージ) → Seven Bank ATM or Lawson Bank ATM
2. The app shows a barcode and a payment number
3. At the ATM, scan the barcode (or enter the number) and insert cash
4. The balance appears in the app immediately

Where this works: Seven Bank ATMs in 7-Eleven and Lawson Bank ATMs in Lawson. The old route through FamilyMart's copy machines has been retired, and no bank account or card is needed.

Method 3: Cards

This is where most foreign residents come unstuck. PayPay can only register PayPay Card and SMBC Card brands — cards issued overseas, and prepaid cards, cannot be added at all. There is no way to top up a PayPay balance with a foreign Visa or Mastercard, so the realistic routes are your Japanese bank account, a PayPay Card, or cash at the ATM.

How to Pay

Show Your QR Code (Customer Code)

Most small shops and individual merchants use this method:

1. Open the PayPay app home screen
2. Tap the large circle icon in the center to display your personal QR code
3. The cashier scans it
4. Confirm the amount and enter your PIN or tap confirm

Scan the Store's QR Code (Recommended for Most Retail)

Most convenience stores, supermarkets, and chain restaurants use this method:

1. Tell the cashier "I'm paying with PayPay" (「PayPay で払います」)
2. In the app, tap Scan (スキャン)
3. Scan the QR code at the register
4. Confirm the amount and enter your PIN
5. When the screen shows Payment Complete (支払いが完了しました)

Making the Most of PayPay Campaigns

PayPay regularly runs promotions including:

• Super PayPay Festival: the big periodic event, with double-digit point-back rates at participating chains
• Local support campaigns: regional campaigns run with local government subsidy, which have offered 20–30% back in participating shops
• Category and time-limited offers: pharmacies, restaurants, supermarkets and specific product categories

How to track campaigns:

1. The Campaigns (キャンペーン) tab on the PayPay app home screen
2. PayPay's official X account: @PayPayOfficial (support: @PayPaysupport)
3. PayPay's official LINE account

Common Problems and Solutions

Not Receiving the SMS Verification Code

• Check that you entered the number correctly, including the Japanese carrier prefix
• Tap Resend — each resend involves a short wait
• Turn off any SMS spam filter or "unknown sender" block on your phone
• SMS-only and prepaid SIMs are the usual culprits; if the code never arrives, a standard carrier or MVNO contract usually fixes it

Account Locked or Suspended

Possible causes: unusual activity detected, repeated wrong password attempts. Solution: Contact PayPay support via the app's Contact Us (お問い合わせ) section, provide your Residence Card and personal information for unlocking — typically resolved within 1–3 business days.

Payment Declined

• Check that your account balance is sufficient
• Confirm your internet connection is working
• Confirm the store accepts PayPay (a small number of stores accept only specific payment methods)

PayPay vs. Other Japan Mobile Payments

One correction to a claim you will see repeated online: d払い does not require a docomo phone line. Any d Account works, whatever network you are on — only the carrier-billing option for charging it needs docomo. Rakuten Pay is similarly open to non-Rakuten users.

We recommend starting with PayPay (broadest acceptance) alongside Suica for transit and small purchases. Between them they cover almost everything an ordinary week in Japan involves.

Final Takeaway

PayPay is the one app worth sorting out in your first week in Japan, and the order of operations matters more than the app itself: get a Japanese phone number, register, then complete identity verification before you top up any meaningful amount. Balances charged before verification sit in Money Lite and can never be withdrawn, and no overseas card or bank account will get money into the app. Once verification is done, you have a payment method that works at more than 10 million locations, runs permanent campaigns, and doubles as a way to pay utility bills and send money to friends.
