Yes, you should absolutely bring Japanese Yen (JPY) to Japan in 2026. While the country has made significant strides toward becoming a cashless society, especially in major cities like Tokyo and Osaka, Japan remains remarkably cash-centric compared to the US or Europe. You will need physical yen for temple and shrine entrance fees, smaller traditional restaurants, local street food stalls, and public lockers. Furthermore, many transit cards (like Suica or Pasmo) often require cash to top up at station kiosks. While credit cards are widely accepted at hotels, department stores, and convenience stores, having a "reserve" of cash is vital for traveling in the countryside or visiting local markets. In 2026, a good strategy is to carry about 10,000 to 20,000 yen at all times for emergencies and small purchases, while using a no-foreign-transaction-fee credit card for larger expenses. ATMs in 7-Eleven stores (7-Bank) are the most reliable way to withdraw cash using international cards if you run low.
