Japan's Secondhand Marketplace Mercari to Integrate Bitcoin Payments

·

In a move that signals growing mainstream adoption of digital currencies, Japan’s leading secondhand e-commerce platform, Mercari, is set to introduce Bitcoin as a payment option. According to a recent report by Nikkei Asia, the integration is expected to launch in June 2025, positioning Mercari at the forefront of the crypto-commerce evolution in Asia.

This development marks a pivotal step for Mercari, which has evolved since its 2013 launch into one of Japan’s most dominant online marketplaces for secondhand goods. While the company has long explored innovations in digital finance, this official move toward Bitcoin payments reflects a broader strategic shift toward embracing blockchain technology and expanding its financial offerings.

Seamless Bitcoin Integration Without Price Volatility

One of the most user-friendly aspects of Mercari’s upcoming feature is how it handles pricing and conversion. Although transactions will be processed using Bitcoin via the Melcoin blockchain—a dedicated layer for crypto payments—prices on the app will continue to be displayed in Japanese yen (JPY). This hybrid model ensures that users benefit from the flexibility of cryptocurrency without being exposed to real-time price fluctuations.

When a buyer chooses to pay with Bitcoin, the system will instantly convert the amount into yen at the current exchange rate. The transaction fee for this service is said to be on par with traditional payment methods such as credit cards or bank transfers, making it both competitive and accessible. However, exact details regarding fee structures, minimum transaction amounts, and wallet requirements have not yet been disclosed.

A Strategic Expansion Into the Crypto Economy

Mercari’s interest in cryptocurrency isn’t new. In March 2023, the company launched an in-app Bitcoin exchange, allowing users to purchase Bitcoin directly through their Mercari accounts. This feature integrates seamlessly with existing account balances, enabling users to buy Bitcoin using funds from bank transfers, sales proceeds, or even loyalty points earned through platform activity.

This gradual rollout—first enabling crypto purchases, now accepting crypto payments—suggests a well-planned entry into the digital asset ecosystem. By building familiarity among its user base first, Mercari reduces friction and increases trust in its new financial tools.

The company’s financial performance further supports this strategic pivot. In its Q3 2023 earnings report, Mercari posted a net profit of 2.8 billion yen (approximately $19.4 million), a significant year-over-year increase. With total sales rising 11.2% to 44.27 billion yen, the business is clearly gaining momentum—making now an ideal time to diversify its services and attract tech-savvy, financially forward-thinking consumers.

Bridging Global Markets: Mercari x Xianyu Partnership

Beyond domestic innovation, Mercari is also expanding its international footprint. In November 2023, Mercari Marketplace, the official overseas shipping partner operated by Beenos Group, officially joined Xianyu, Alibaba’s secondhand trading platform often referred to as China’s “Idle Fish.”

This cross-border collaboration brought nearly 100,000 anime and pop culture collectibles to Chinese consumers, including rare PSA-graded Pokémon cards and premium editions of sought-after designer toys like the gold-plated "Brave Bear" lucky cat—items popularized by celebrities and collectors alike.

According to Beenos Group’s China division head, “Xianyu and Mercari are the largest secondhand platforms in their respective markets. Their algorithms, user behavior patterns, and audience demographics align closely. We’re starting with high-demand anime and collectible brands, with plans to make Xianyu a primary gateway between Mercari and Chinese secondhand shoppers.”

This partnership not only boosts Mercari’s global visibility but also introduces a new cohort of users who may eventually adopt its crypto-enabled features—especially if Bitcoin payments become available on international storefronts in the future.

Why This Move Matters for E-Commerce and Crypto Adoption

Mercari’s decision to integrate Bitcoin goes beyond mere trend-chasing. It represents a meaningful step toward normalizing cryptocurrency in everyday transactions. For years, skeptics have questioned whether digital assets could function as practical mediums of exchange rather than just speculative investments. Mercari’s real-world implementation offers a compelling counter-narrative.

By handling conversion behind the scenes and maintaining yen-based pricing, Mercari minimizes complexity for average users while still leveraging the speed and decentralization benefits of blockchain networks like Melcoin. This approach could serve as a blueprint for other e-commerce platforms considering crypto integration.

Moreover, Japan has long been a leader in progressive crypto regulation and financial innovation. With clear guidelines from regulators and widespread public trust in digital payment systems, the country provides fertile ground for experiments like this one.
