In a startling series of events, three robbery attempts linked to Hong Kong currency exchange occurred within a 14-hour window in Japan, underscoring the persistent risks associated with carrying physical cash. These incidents serve as a stark reminder that even in an era dominated by credit cards, digital transfers, and cashless payment apps, cash remains a vulnerable yet essential fallback. While the convenience of digital payments is undeniable, the reliance on technology introduces its own set of vulnerabilities, as recent disruptions have shown.

The bankruptcy of ZENTOSHIN, a major payment processing agency, has triggered concerns about credit card reliability at select restaurants, with rumors swirling that up to 200,000 outlets might stop accepting card payments. However, it’s crucial to clarify that this figure stems from 2018 statistics and does not reflect the current scale of the issue. The actual damage is under investigation, and Japan’s nationwide credit card payment infrastructure remains fully operational. This incident highlights the fragility of digital payment systems and the importance of having cash on hand as a contingency, especially when technological glitches or corporate failures can temporarily disrupt services.

Interestingly, despite these challenges, Japan is witnessing a historic shift away from cash. In 2025, the country’s monetary base—cash in circulation—declined for the first time in 18 years, a direct result of the Bank of Japan’s (BOJ) policy normalization. After ending a decade-long stimulus in March 2024, which included massive asset buying and negative interest rates, the BOJ is gradually reducing its support, signaling confidence in achieving its 2% inflation target. This trend is likely to persist, encouraging a gradual move toward cashless transactions, even as the practical need for cash remains.

For residents and visitors alike, the key takeaway is balance. Carrying a modest amount of cash is prudent, given the potential for digital payment disruptions, but hoarding large sums is risky. The recent robberies and payment system hiccups serve as cautionary tales, reminding us that while cash is a reliable backup, its physical nature makes it a target. As Japan navigates this transition, staying informed and adaptable will be essential for managing finances securely in an evolving landscape.
