PayPay to Open Japan Merchant Network to WeChat Pay Users From Mid September

A familiar Chinese wallet at Japanese checkouts

PayPay plans to begin accepting payments from Weixin Pay (WeChat Pay) users at millions of affiliated merchants across Japan in mid September 2025, connecting a major Chinese mobile wallet with a nationwide Japanese payment network. Chinese travelers will be able to use their familiar app to scan a PayPay QR code, while participating stores receive payment in yen through PayPay.

The launch comes as travel from mainland China grows sharply. The Japan National Tourism Organization (JNTO) recorded 797,900 visitors from mainland China in June 2025, an increase of 19.9 percent from a year earlier. More than 4.71 million arrived during the first six months of the year, up 53.5 percent.

Weixin and its international service, WeChat, together have more than 1.4 billion monthly active users. Connecting WeChat Pay to PayPay gives travelers access to more places where they can pay without changing apps, while helping Japanese businesses accept foreign wallet payments through a process close to the one they already use.

The connection runs through HIVEX, a framework from TBCASoft that links mobile payment systems across markets. Its job is to carry payment requests and confirmations between networks that would otherwise operate separately.

As of September 6, the companies had announced a launch window of mid September 2025, without specifying an exact day. PayPay describes the addition as part of its continuing effort to accept more overseas wallets in Japan. Its official launch announcement sets out the planned connection.

Where travelers will be able to pay

PayPay says the service will extend across its nationwide merchant network, bringing WeChat Pay acceptance to millions of affiliated locations. The intended coverage includes convenience shops, specialty retailers, restaurants and other food and beverage businesses, attractions, taxis, hotels and other lodging.

For a visitor moving between shops, meals, transport and accommodation, that breadth could make payment more predictable. Instead of checking whether each business has a separate arrangement with WeChat Pay, the traveler would use the PayPay QR code at participating locations.

Stores are expected to retain the same basic experience that staff use for domestic PayPay QR payments. PayPay says its network will continue to grow, with the WeChat Pay connection becoming part of that existing store process.

The timing places the launch ahead of the autumn travel season and year end holidays, periods when visitor traffic typically rises again. Demand connected with the Osaka Kansai Expo is also part of the tourism setting for the planned expansion.

How a payment will work

A customer will open Weixin or WeChat, select WeChat Pay and scan the PayPay QR code presented at the checkout. The code may appear on a stand or a terminal screen. The purchase amount appears inside the wallet, and the customer approves it using a passcode, biometrics or another authentication method supported by the device.

Biometrics means using a physical feature, such as the recognition method available on a phone, to confirm the user's identity. The important practical point is that the customer authorizes the purchase inside the familiar WeChat Pay app.

A payment confirmation then appears for the buyer and the merchant. The planned experience is intended to complete purchases in seconds, with HIVEX carrying the request from the PayPay QR system to WeChat Pay for authorization.

The traveler is charged in the currency of their home wallet. PayPay settles with the merchant in yen through its normal settlement cycle. Settlement is the process through which the business receives the money from a completed sale.

Currency conversion happens automatically under the participating networks' rules. For that purchase, the traveler does not need to exchange cash or find the right Japanese notes and coins. The exchange rate and any wallet fees are determined by the networks involved.

What HIVEX does behind the checkout

TBCASoft runs HIVEX as a framework connecting wallets across countries and brands. It supplies shared business rules, technical connections and consistent branding so a payment from a foreign wallet can reach a local merchant's payment network securely and reliably.

For PayPay and WeChat Pay, HIVEX acts as the bridge between their systems. It maps the information contained in QR codes, validates payment requests and returns authorizations in near real time. In simple terms, it helps each system understand the transaction sent by the other.

TBCASoft says the aim is to make international mobile wallet payments feel familiar on both sides of the sale. Ling Wu, the company's chief executive, described the collaboration as bringing together the Chinese wallet, the Japanese merchant network and the connecting framework.

This partnership brings together three market leaders Weixin Pay (WeChat Pay) in China, PayPay in Japan, and HIVEX to create a powerful proposition for both travelers and merchants.

HIVEX also reduces the need for every wallet to build a separate connection with every merchant payment provider. A single connection to the framework can provide access to several partners operating under common rules.

For a merchant, the intended result is straightforward: more overseas customers can use their own wallets while the store continues to handle a standard PayPay transaction. PayPay has highlighted the framework's role in making the service available across a large number of locations through a streamlined integration.

The tourism figures behind the launch

Mainland China was Japan's largest source of inbound visitors in June 2025, according to JNTO's monthly breakdown. The 797,900 arrivals that month were part of a broader recovery that had already brought more than 4.71 million mainland Chinese visitors to Japan in the first half of the year.

The figures show two measures of that growth: June arrivals rose 19.9 percent from a year earlier, while arrivals across the first six months rose 53.5 percent. Both point to a larger pool of potential customers for businesses serving Chinese visitors.

PayPay's announcement also cited record visitor levels for July and said Japan had passed 20 million inbound visitors in the first half of a year faster than ever before. Retail, dining and purchases connected with travel are among the spending categories served by the merchant network.

The companies are seeking to turn that visitor demand into completed purchases. A customer who recognizes the payment app and understands its prompts may find checkout easier than when handling unfamiliar cash or card instructions. The intended commercial benefits include smoother queues and a better chance that a shopper completes a purchase.

Familiar wallet acceptance can also support higher average purchase values. For retailers, restaurants, transport operators and hotels, the attraction is the opportunity to make payment easier at the point where a visitor decides whether to buy.

How the expansion developed

PayPay has been building acceptance for overseas wallets since 2018. The WeChat Pay plan adds a large Chinese user base to a wider effort to connect foreign payment services with Japanese merchants.

The main dates and figures leading into the planned launch are:

• 2018: PayPay began its continuing expansion of overseas wallet acceptance.
• January to June 2025: Mainland Chinese arrivals in Japan exceeded 4.71 million, up 53.5 percent from a year earlier.
• June 2025: JNTO recorded 797,900 mainland Chinese visitors, an increase of 19.9 percent.
• July 2025: PayPay's announcement cited record inbound visitor levels.
• September 6, 2025: The planned WeChat Pay service remained scheduled for mid September.
• Mid September 2025: Acceptance through the PayPay merchant network is scheduled to begin.

PayPay says users of 26 services from 14 countries and regions can now pay at its merchants. The services it names include Alipay, AlipayHK, Kakao Pay, Toss, NAVER Pay, GCash, TrueMoney, Kaspi kz, Tinaba, JKO PAY, Bluecode and Touch n Go, among others.

WeChat Pay is intended to use the same broad route for accepting overseas wallets. The value for merchants is that another large group of potential customers becomes reachable without a separate checkout system for each wallet.

What changes for Japanese businesses

Shops, cafes, attractions and hotels are expected to accept the new payments using their existing PayPay QR materials, without new hardware or an extra app. Staff training should be limited because the payment flow remains close to the familiar domestic process.

A traveler sees the wallet interface in simplified Chinese inside WeChat Pay, while the business continues to receive yen and use PayPay's reporting and reconciliation tools. Reconciliation means matching recorded sales with the payments the business receives.

Merchants can display WeChat Pay acceptance signs alongside the PayPay logo so visitors know the option is available before reaching the register. Chinese language signs may be particularly useful in districts with heavy tourist traffic.

The main operational benefits described for businesses are:

• Accept WeChat Pay through an existing PayPay QR code, without new hardware or additional apps.
• Receive settlement in yen through PayPay, with familiar reporting and reconciliation.
• Make checkout easier for Chinese visitors who prefer paying by QR code.
• Use HIVEX routing and shared rules to support a consistent experience across participating foreign wallets.

Staff can continue to present the QR code, check the amount on screen and look for the payment completion message. Training can include simple ways to tell visitors that WeChat Pay is accepted, such as pointing to the PayPay code and naming the wallet.

Refunds, receipts and the cost of paying

Refunds and cancelled transactions typically follow the route used for the original payment. A return processed by a PayPay merchant would travel back through HIVEX to WeChat Pay, crediting the customer's wallet and using the reference attached to the original sale.

Travelers can view receipts and transaction history inside WeChat Pay, while merchants use the PayPay dashboard. Store procedures are expected to resemble an ordinary QR payment return, using existing PayPay materials.

The companies have not published a fee schedule specifically for this connection. Merchants are expected to receive yen through PayPay, while travelers see a charge in their wallet's home currency, with conversion rates and any wallet charges governed by the participating networks.

Businesses should check their PayPay merchant materials for acceptance rules and guidance on recognizing WeChat Pay transactions passing through the same QR payment route. Merchants using integrated point of sale software should also check whether those transactions are labeled clearly for reconciliation at the end of the day.

Exchange rate display, the time needed for a refund after a traveler has left Japan, and support across time zones remain practical questions for users and businesses. Settlement timing, chargeback rules and dispute procedures are governed by the networks involved. A chargeback is a process for challenging a payment.

Security and protection across the networks

PayPay says its services operate under Japan's financial rules and registration requirements. The company also points to measures intended to protect users, including compensation schemes for unauthorized payments.

HIVEX and WeChat Pay operate through their respective licensed payment systems, with transactions designed to meet the requirements of the markets involved. HIVEX's shared business rules cover the handling of payments from authorization through settlement and disputes.

For the traveler, approval takes place inside WeChat Pay rather than through an unfamiliar payment app. For the merchant, PayPay's settlement and reporting process continues to apply.

Stores and visitors will still need to understand the procedures relevant to a particular payment, especially when seeking help or returning goods. Keeping the transaction reference and digital receipt makes it easier to identify the original purchase within the systems used by the buyer and the merchant.

Where the connection fits into everyday payments

Japan's payment options include cards, contactless payments, transit cards and QR wallet apps. PayPay helped spread domestic QR payments by giving small businesses a low cost way to accept smartphone payments without a dedicated terminal.

Shopping streets and malls serving tourists often display several payment logos, including Japanese wallets and overseas services such as Alipay. Adding WeChat Pay through PayPay allows participating storefronts to serve domestic customers and another group of overseas visitors through the same QR sign.

Travelers using a familiar wallet face fewer language difficulties and fewer unfamiliar payment prompts. Businesses can spend less time handling cash at busy registers. In popular shopping districts and along tourist routes, accepting a payment method visitors already use can help a store compete for their spending.

Busy locations still present practical problems. Crowded venues can have weak or congested connectivity, slowing a QR payment. Merchants may need to position QR stands where the signal is stronger or provide Wi Fi coverage near the cashier.

Staff should also have another payment option ready when a phone has little battery power or a scan fails. Travelers may want to retain the digital receipts in their WeChat Pay history for duty free paperwork or expense claims. The planned connection simplifies the payment route, while these everyday checkout tasks remain part of making it work smoothly.
