1, about a week, I suggest you bring about 65,438+10,000 yen in cash, because small shops selling local products and places where you eat every day may encounter places where you can't use credit cards, such as going to a 24-hour convenience store to buy things.

If you don't buy luxury goods, the credit card limit of 2 million yen is enough. I think 654.38+00,000 yen is enough. In a week or so, you can spend about 6.5438+0 million RMB a day, right?

3. It is suggested that you bring a bank debit card of UnionPay with thousands to 10,000 RMB deposits on it-if you are short of Japanese yen cash when you are in Japan, you can withdraw Japanese yen directly from the ATM of Mitsubishi UFJ Bank in Tokyo, Japan, with a handling fee of 15-30 yuan RMB per transaction. The ATM of Mizuho Bank is also available, with Chinese prompts.
