What Does a Bitcoin-Enabled Japanese Department Store Look Like?

·

In a quiet but groundbreaking shift, Japan’s retail landscape is embracing cryptocurrency like no other country. When Marui Group's ANNEX department store in Tokyo began accepting Bitcoin payments, it wasn’t just another tech experiment—it signaled a deeper integration of digital currency into everyday life. For crypto enthusiasts like Takayuki Takayama and Pengfei Wang, this wasn’t just news—it was an invitation to explore firsthand what it means to pay with Bitcoin in one of the world’s most advanced retail environments.

A New Era of Retail: Paying with Bitcoin at Marui ANNEX

Located near Shinjuku Station—one of Tokyo’s busiest commercial districts—Marui ANNEX has become a testing ground for cryptocurrency adoption. Since launching Bitcoin payments, the store has rolled out promotional posters highlighting the new option, making it clear that digital currency is no longer niche.

Customers can now spend up to 100,000 JPY (approximately $600 USD) per transaction using Bitcoin. As an added incentive during the trial phase, shoppers spending over 3,000 JPY (~$18 USD) enter a lottery for a chance to win 3,000 JPY worth of Bitcoin.

“It’s just like scanning Alipay,” said Takayama. “The payment goes through instantly. It’s seamless.”

But behind this simplicity lies a complex ecosystem of technology, regulation, and consumer trust—all converging in real time.

How Does In-Store Bitcoin Payment Actually Work?

Despite Bitcoin’s original promise of peer-to-peer transactions without intermediaries, the reality of point-of-sale payments is more nuanced.

Here’s how it works at Marui ANNEX:

  1. After selecting items, the customer informs the cashier they want to pay with Bitcoin.
  2. A dedicated crypto staff member approaches with an iPad.
  3. The item total is entered in Japanese yen.
  4. A dynamic QR code appears on screen, showing both the yen amount and its real-time Bitcoin equivalent based on current exchange rates.
  5. The customer scans the code using the Bitflyer wallet app to complete the transaction.

While this process feels instantaneous—similar to mobile payment platforms like WeChat Pay or Apple Pay—it doesn’t involve direct blockchain settlement at that moment.

Rumi Kobayashi, Senior Researcher at QRC Japan—a blockchain regulatory technology firm—explains:

“True peer-to-peer Bitcoin transactions typically take around 10 minutes to confirm on the blockchain. What we’re seeing here isn’t pure P2P transfer; instead, it’s an off-chain exchange facilitated by Bitflyer.”

In essence, both users and merchants hold their Bitcoin within Bitflyer’s closed-loop system. When a purchase is made, funds are debited from one internal wallet and credited to another—no actual blockchain transaction occurs during checkout. This design bypasses network congestion and confirmation delays, enabling instant payments while maintaining security.

However, this convenience comes with limitations: only customers using the Bitflyer wallet can participate.

Behind the Scenes: Bitflyer and Japan’s Crypto Infrastructure

The backbone of this innovation is Bitflyer, Japan’s largest Bitcoin exchange. Known for its strict compliance with financial regulations, Bitflyer has positioned itself as a bridge between traditional retail and decentralized finance.

It’s not just Marui ANNEX. Bitflyer has also powered Bitcoin payments at major retailers like BicCamera and Peach Aviation, Japan’s low-cost airline. These partnerships reflect a broader trend: Japanese corporations are increasingly viewing cryptocurrency not as speculative tech, but as a viable payment rail for the future.

Marui Group, founded in 1937, has long been a pioneer in consumer finance—famously introducing credit cards to Japan in 1960. Now, they’re doing the same for digital assets. With 31 stores nationwide, the company plans to expand Bitcoin payments beyond the ANNEX location if the pilot proves successful.

Why Japan Is Leading the Global Crypto Adoption Curve

Japan’s embrace of cryptocurrency didn’t happen overnight. It was catalyzed by policy.

In March 2025, the Japanese Cabinet passed the Cabinet Office Ordinance on Virtual Currency Exchange Operators, officially recognizing Bitcoin as a legitimate payment method. The law took effect in April 2025, paving the way for widespread merchant adoption.

Since then, momentum has built rapidly:

“Japan represents one of the most mature markets for cryptocurrency use,” says Adam Vaziri, member of the UK Digital Currency Association. “Even though true decentralized transactions aren't yet mainstream, being able to buy goods directly without converting to fiat marks a significant step toward real-world utility.”

Still, public trust had to be rebuilt after the 2014 collapse of Mt. Gox—the Tokyo-based exchange that once handled 70% of global Bitcoin trades. The theft of 850,000 BTC shattered confidence and exposed critical vulnerabilities in early crypto infrastructure.

In response, Japan established the Japan Blockchain Association (formerly JADA), setting strict standards for Know Your Customer (KYC), anti-money laundering (AML), and cybersecurity practices. These measures helped restore credibility and laid the foundation for today’s regulated yet innovative ecosystem.

Frequently Asked Questions (FAQ)

Q: Can I use any wallet to pay with Bitcoin at Marui ANNEX?
A: No. Only customers using the Bitflyer wallet can make payments, as transactions occur within Bitflyer’s internal system rather than directly on the blockchain.

Q: Is this truly a peer-to-peer Bitcoin transaction?
A: Not exactly. While marketed as Bitcoin payment, it's actually an off-chain transfer between Bitflyer-hosted wallets—similar to moving money within a bank app. True P2P settlement happens later during batch processing.

Q: Are there spending limits?
A: Yes. The maximum per transaction is 100,000 JPY (~$600 USD). Minimum qualifying purchases for promotions start at 3,000 JPY.

A: Strong regulatory clarity since 2025, combined with proactive corporate innovation and lessons learned from past failures like Mt. Gox, have created a balanced environment for safe experimentation.

Q: Will more stores adopt Bitcoin soon?
A: Yes. With Marui planning expansion across its 31-store chain and companies like BicCamera and Ulmart following suit, broader adoption is likely—especially if user experience remains frictionless.

Q: Does using Bitcoin offer any advantages over credit cards?
A: For consumers: faster checkout and potential rewards in crypto. For merchants: lower risk of chargebacks and access to a tech-savvy customer base.
