I want to travel to Japan in June 1 1. What preparations do I need to make?

As I will leave in 1 1, I don't have to worry about the weather now. Just check it online when you come. I just got back from Japan the other day. Don't worry about H 1N 1 there. It's okay. Just play normally. If it is winter, you don't need to bring a lot of clothes, just a few sets. Better bring enough underwear or something. Laundry there is very expensive. If you want to do it yourself. Very convenient. If you are a lady, don't wear high heels and flats. If you wear slippers, some big hotels in Osaka, Tokyo have disposable slippers, and only some small hotels or hot spring hotels have slippers that are reused. If you are not used to it, bring a pair yourself. It will be very convenient if you have a VISA card to spend there, because small shops in Japan can even swipe their cards sometimes. As for UnionPay, it is not as common as VISA. Can only be used in some places. Electrical appliances, most of the household appliances we use now can be used in Japan. You can see if there is anything written on it. Computers are basically ok. If you can't buy a converter, you don't have to buy it, because it's basically useless. I bring a computer or something. As for the mobile phone, it can't be used even if it is turned on there. Because Japanese mobile phones are all developed by themselves, neither GSM nor CDMA can be used. If you want to set an alarm clock, you can book a wake-up call at the hotel. Finally, because many foods in Japan are raw, some people can't get used to them, so you must bring some antidiarrheal drugs or something. I think you should also bring some cold medicine. When you first arrive there, you will be a little unaccustomed, and your body will probably catch a cold. That's what I did. I had a bad cold on my first day in Japan. In addition, if I go to Japan for free activities, don't take a taxi unless there are special circumstances. It is very expensive. Just take the subway. It's very convenient. You can go almost anywhere. The subway in Tokyo is very developed, and even the route map of Japan is written in Chinese, which is understandable.

I hope you have a good time!
