While Tokyo has become significantly more "cashless" in 2026, it is still essential to carry some physical currency. Major department stores, hotels, and convenience stores like 7-Eleven or Lawson all accept international credit cards and mobile payments (Apple Pay/Google Pay). However, many of Tokyo’s most iconic experiences still require cash: small family-run izakayas, traditional ramen shops with "ticket machines," and many neighborhood cafes remain cash-only. Additionally, entrance fees at temples and shrines, as well as many coin-operated lockers at train stations, only accept physical yen. A vital tool for any Tokyo visitor is a digital Suica or Pasmo card on your phone; while these can be topped up with a credit card, they act as a "digital wallet" for transit and thousands of small retailers. A good rule of thumb is to keep ¥10,000–¥20,000 in your wallet for emergencies and small vendors. Even as Japan pushes for 65% cashless transactions by 2030, the "cash is king" culture persists in the very places that offer the most authentic glimpses of Tokyo life.
