Whether you’re a digital nomad, a long-term resident, or a tourist, going cashless in Japan is now easier than ever.

1. Why Japan Is Going Cashless

Historically, Japan has been a cash-based society. Even in the 2010s, it was not unusual for people to carry ¥50,000–¥100,000 in their wallets.

However, several factors have accelerated the shift:

• COVID-19 encouraged contactless payments

• The Japanese government introduced incentives for stores adopting cashless tech

• Foreign tourism and e-commerce demands required faster, global-friendly options

• Younger generations increasingly prefer mobile payments

By 2025, Japan aims for 40% of all transactions to be cashless.

8. Where You Can Use Cashless Apps

9. Tips for Using Cashless Apps Without Japanese

• Use Google Translate camera to scan menus, buttons, or QR codes

• Bookmark your QR code screen in the app for quick access

• Ask store staff: 「ペイペイ使えますか？」(Peipei tsukaemasu ka?)

• Keep ¥1,000–¥2,000 in cash for emergencies

Japan is not 100% cashless—some rural areas and clinics still prefer cash.

10. Pros and Cons of Going Cashless in Japan
