Japan’s digital payment giant, PayPay, has acquired a 40% stake in Binance Japan, marking a significant collaboration announced on October 9, 2025. This partnership aims to merge PayPay’s network, reaching over 70 million users, with Binance’s blockchain infrastructure to seamlessly bridge fiat and cryptocurrencies. Onboarding “PayPay Money” within the Binance Japan app will facilitate cryptocurrency transactions and enable funds to be transferred back to PayPay Money. Based in Tokyo, Binance Japan, a registered crypto exchange with the Kanto Local Finance Bureau, has been offering spot trading and yield products since August 2023.
Blending Payment and Cryptocurrency Experiences into One Stream
A press release detailed the integration of PayPay’s cashless payment ecosystem with Binance’s global cryptocurrency technology. The goal is to allow users to manage fiat and cryptocurrency transactions in a singular app experience. The PayPay Money integration will accelerate adoption by enabling direct balance usage for purchasing cryptocurrencies and transferring sales proceeds into the PayPay wallet. The announcement underscored aims to enhance Web3 accessibility across the country and provide secure, uninterrupted cryptocurrency services.
A part of the SoftBank Group, PayPay operates one of Japan’s widest-reaching cashless payment infrastructures. This agreement strategically leverages PayPay’s user scale with Binance’s products to accelerate the integration of cryptocurrency payments among individuals. The announcement also mentioned PayPay’s 40% stake in Binance Japan and the potential for co-developing products and services.
Regulatory Framework and Market Impact
Operating within the Japan Virtual and Crypto Assets Exchanges Association (JVCEA) ecosystem, Binance Japan functions under the registration of the Kanto Local Finance Bureau. The integration of a domestic payment infrastructure like PayPay Money into a licensed exchange app potentially expands crypto access within a familiar wallet-balance model under a regulatory framework. This approach merges the security-compliance standards of payments with the market access of cryptocurrencies within the same user flow.
From a macro perspective, the integration, aligning with Japan’s cashless economy goals, could boost market interest. PayPay’s substantial user base of 70 million could create a scale effect in linking cryptocurrencies with daily financial activities, from micro‑payments to savings products. As of the agreement’s announcement date, PayPay’s investment positions Binance Japan as an equity‑method accounted affiliate.
