Travel to Japan in early August, please let the experienced people know.

Hokkaido is an island, which is quite far from Honshu Island, especially the earthquake site, so there is no need to worry about radiation. To tell the truth, the China media's coverage of domestic affairs tends to roll with the punches, while it embellishes foreign affairs for fear that it is not lively enough. Your mother went with a group, so don't worry. Travel agencies don't take tourists to dangerous places.

It's good to go to Hokkaido at this time. Hokkaido has high latitude and low temperature, so it can escape the summer, hehe. Just bring clothes in summer, a thin long-sleeved coat just in case. Because it is a group tour, accommodation should be solved. Cosmetics (travel clothes), a pair of light shoes and some useful clothes are probably enough. Japan's service industry has an excellent attitude. If you need to talk to a tour guide, the tour guide will help you. If you get carsick, take some carsick pills.

As for money changers, it depends on your budget. What are you going to buy in Japan? If it is cosmetics, a set of Shiseido cosmetics (lotion+lotion) usually costs 56,000 yen; It's nearly ten thousand yen expensive. If you buy electrical appliances, such as rice cookers, it will cost about 30 thousand yen. However, the general tour group should be able to use UnionPay cards wherever they want to go.

The current exchange rate is 100 yen to 8 yuan RMB, and 2,000 yuan is more than 20,000 yen. I think I can.

All the above are personal opinions, please refer to them.
