PayPay Acquires 40% Stake in Binance Japan: Transforming Japan’s Digital Finance Ecosystem
SoftBank’s mobile payment platform, PayPay, has acquired a significant 40% equity stake in Binance Japan, the Japanese arm of the global cryptocurrency exchange Binance. The agreement was solidified through a capital and business alliance, as reported by Cointelegraph on October 9. By September 2025, Binance Japan will officially become an equity-method subsidiary of PayPay, marking a key milestone in Japan’s financial integration of cashless payments and digital assets.
A New Era of Digital Asset Integration
This innovative partnership is set to revolutionize payment services in Japan by enabling Binance users to trade digital assets directly using PayPay Money. PayPay highlighted its strategic evolution “from a cashless payment platform to a digital financial ecosystem” and reiterated its commitment to improving Japan’s financial infrastructure. The company emphasized that this venture aims to stimulate economic growth and unlock new economic opportunities by bridging the gap between traditional finance and cutting-edge digital asset technologies.
Leveraging the Synergy Between PayPay and Binance
Masayoshi Yanase, a key strategist at PayPay, detailed the complementary strengths of the two companies. "PayPay has pioneered smartphone-based digital financial innovation through collaborations with financial affiliates. By investing in Binance Japan, the Japanese subsidiary of the world's leading cryptocurrency exchange, we hope to deliver an unprecedented level of convenience and security for users," Yanase stated.
Echoing this optimism, Takeshi Chino, CEO of Binance Japan, commented, "The integration of PayPay’s expansive user base and Binance’s advanced blockchain technologies will allow us to offer safer and more seamless Web3 asset services across the country." This collaboration enables the promise of delivering accessible, secure, and efficient solutions to Japanese users, making Web3 more mainstream in the region.
PayPay’s Meteoric Growth in Japan
Since its launch by SoftBank in 2018, PayPay has emerged as a dominant force in Japan’s cashless payment ecosystem. The platform reached an astounding 70 million users as of July 2025, showcasing its rapid adoption across the nation’s population. In addition, PayPay has reported exponential growth in remittance transactions, hitting 380 million in 2024—a 36% increase from 280 million the year before.
In contrast, Japan’s traditional bank remittance growth during the same period was a modest 7.5%, underscoring PayPay’s transformative impact on how people and businesses handle financial transactions. This momentum has proven PayPay’s ability to cater to Japan's evolving digital payments landscape while outpacing conventional banking services.
Global Ambitions and U.S. IPO Plans
As PayPay solidifies its dominance in Japan, the company is pushing ahead with global expansion initiatives. September marked PayPay’s entry into South Korea, widening its footprint in the Asian market. Following this, PayPay confidentially filed with the United States Securities and Exchange Commission (SEC) in August to list American Depositary Shares (ADS) in one of the most anticipated IPO events in the global tech space.
Although details surrounding the IPO’s timing, size, and pricing remain undisclosed, PayPay stated that decisions would hinge on "market conditions and other considerations." This move signals the company’s ambition to become a global digital payments leader while aiming to attract investors in one of the largest capital markets in the world.
Binance’s BNB Token Rally: Market Response
The announcement of the PayPay-Binance Japan partnership coincided with a major rally in Binance’s ecosystem token, BNB. As of October 8, BNB was trading at approximately $1,300, marking an impressive 26% surge over the previous week. The token’s market capitalization hit $182 billion, securing its position as the third-largest cryptocurrency by market cap.
Analysts attribute this market optimism to the potential of the partnership to redefine Web3 adoption in Japan and beyond. One industry expert noted, “The combination of PayPay’s convenience-driven platform with Binance Japan’s robust digital asset solutions is a game-changer. This collaboration will improve access to digital asset payments within Japan and expand practical use cases for Web3 technologies.”
By forging this strategic alliance, PayPay and Binance Japan are leading the charge to integrate digital assets into everyday financial systems. This game-changing partnership not only enhances Japan’s standing in the world of financial innovation but also sets the stage for broader Web3 adoption and inclusive digital financial services. With its rapid growth, global expansion aspirations, and intensive focus on security, PayPay is more than a local payment solution—it’s fast becoming a global fintech trailblazer.
