Japan is rapidly positioning itself as a frontrunner in the global movement toward regulated and user-friendly cryptocurrency payments. While not recognizing Bitcoin as legal tender, the country has cultivated one of the most progressive regulatory environments for digital assets, paving the way for widespread adoption across retail, e-commerce, and financial services.
Back in 2017, Japan made headlines by officially allowing merchants to accept Bitcoin as payment—a landmark move that placed it among the first nations to embrace crypto in everyday transactions. This was shortly preceded by the establishment of one of the world’s earliest comprehensive regulatory frameworks for cryptocurrencies, setting a precedent for compliance-driven innovation.

Since then, momentum has steadily built. The Japanese government, particularly through its ruling Liberal Democratic Party (LDP), has actively supported Web3 development. The release of the Japan Web3 White Paper 2023 underscored this commitment, outlining strategies to reduce regulatory burdens on blockchain projects while promoting growth in key areas such as NFTs and blockchain gaming.
This forward-thinking approach has encouraged major retailers and tech companies to integrate crypto payment options, signaling a cultural and commercial shift toward digital asset utilization.
Major Retailers Embrace Cryptocurrency
One of the earliest adopters was Marui, a prominent department store chain, which partnered with Japanese crypto exchange Bitflyer in 2017 to accept Bitcoin payments across 31 of its locations. This pilot sparked a ripple effect throughout the retail sector.
Yamada Denki, Japan’s largest consumer electronics retailer, followed suit in 2018 by launching a trial Bitcoin payment system in two Tokyo stores—also in collaboration with Bitflyer. Due to positive consumer response, the initiative expanded nationwide, making digital currency payments accessible to millions of shoppers.
The trend continues today, with more businesses recognizing the value of catering to tech-savvy, digitally native consumers. Notably, Mercari, Japan’s leading online marketplace akin to eBay or Craigslist, announced earlier this year that it would begin accepting Bitcoin on its popular flea market app. The company cited growing demand from its digital-first user base and emphasized its ongoing commitment to innovation and customer convenience.
These developments reflect a broader transformation: cryptocurrency is no longer confined to niche tech circles but is increasingly viewed as a viable alternative to traditional fiat in real-world commerce.
Regulatory Challenges and Tax Hurdles
Despite its leadership role, Japan maintains a cautious and highly regulated stance on digital assets. It enforces some of the strictest compliance requirements globally for crypto asset service providers (CASPs). Firms must be incorporated entities in Japan or, if foreign-based, establish a local office and obtain formal licensing from the Financial Services Agency (FSA).
Capital adequacy rules are stringent, designed to ensure financial stability and investor protection. Additionally, Japan has tightened oversight on stablecoins—only licensed banks and registered financial institutions may issue them. These assets must be backed by yen-denominated deposits held within Japanese banks, ensuring transparency and minimizing systemic risk.

Taxation remains another significant barrier. Cryptocurrency gains are classified as "miscellaneous income" under Japanese law, subject to a progressive tax rate that can reach up to 55%. This high burden discourages active trading and has prompted some crypto firms to consider relocating operations overseas.
Nonetheless, these challenges have not stifled innovation—they’ve instead inspired creative solutions that operate within the boundaries of the law.
Innovation Within Compliance: The Rise of Slash
Amid regulatory constraints, homegrown startups like Slash have emerged as pioneers in compliant crypto payment infrastructure. Slash has developed a Web3 payment application that supports over 1,400 cryptocurrencies, enabling seamless transactions across e-commerce platforms, Web3 services, and physical stores.
Leveraging Japan’s rapid shift toward cashless payments—driven by mobile wallets like PayPay and Rakuten Pay—Slash integrates easily into existing systems via API or QR code scanning, offering merchants a familiar checkout experience with blockchain-backed efficiency.
What sets Slash apart is its clever workaround to Japan’s tax and regulatory hurdles: it facilitates crypto-to-crypto exchanges only, ensuring users never convert digital assets into fiat currency. By avoiding fiat conversion, Slash sidesteps the complex tax implications tied to realized gains, allowing consumers to spend their crypto freely without triggering taxable events.
Founded in 2022 after securing $1.5 million in seed funding, Slash has quickly gained traction. It collaborates with major players like **SoftBank** and **Zaif**, and has integrated with **Bybit’s Japanese exchange platform**. To date, Slash powers payments for over **3,000 merchants** and has processed more than **$10 million in transaction volume** as of October 2024—an impressive testament to market demand.
Looking ahead, Slash plans to launch a crypto-linked credit card later this year, connecting users’ digital wallets directly to a physical payment method. This innovation could dramatically expand crypto usability across Japan’s vast retail network.
