Though use of credit cards and e-currency has increased in recent years, Japan is still largely a cash-based society. Here we send some useful information for your visit to Japan.
The national currency of Japan is the Japanese Yen (¥). Most of large stores, restaurants, and taxi accept major credit cards, VISA, Master, UnionPay, and some debit cards. However, some small stores and lunch places still only accept cash. It is best to exchange cash before leaving your country. Otherwise, you can withdraw cash with your bank card or credit card at an ATM at the airport upon arrival. ATMs are located as soon as you exit the arrival gate at the airports. Considering that cards and electronic money are accepted, 20,000 yen in cash would be sufficient for a week. See also this link.
