While Japan has become significantly more credit-card friendly in recent years, it remains a heavily cash-reliant culture, especially in smaller towns, temples, and local eateries. It is highly recommended to exchange a small amount of Japanese Yen (around 10,000 to 20,000 JPY) before you arrive to cover immediate expenses like airport transport, snacks, or initial bus fares. However, for the bulk of your spending, you will likely get a much better exchange rate by withdrawing Yen from ATMs inside Japanese 7-Eleven stores (7-Bank) or Japan Post offices once you land. These ATMs are ubiquitous and generally accept international debit cards with lower fees than traditional airport exchange kiosks. As of 2026, digital "IC cards" like Suica or Pasmo (often available via Apple Wallet or Google Pay) are the preferred way to pay for almost all public transit and many convenience store purchases, which reduces the need to carry massive amounts of physical coins. Nevertheless, having physical cash on hand is essential for traditional "Ryokan" stays or shopping at local "Shotengai" street markets where digital payments are still not universal.
