Hello ~
I once studied in Japan for a year, and I do take as little as I can, because it is very convenient to buy there.
Clothes are very cheap when they are on sale, but the styles are all Japanese and strikingly similar. If you don't like this style, you can bring more clothes you like. Of course, first-line luxury is definitely cheaper than domestic luxury, and there are many Japanese-limited models.
if you cook your own food, you are advised to bring some favorite seasoning packages, laodopted mother, hot pot bottom materials, thick soup treasures and so on. China's seasoning will be more expensive in Japan. There are also half-price or discounted lunches sold in supermarkets at night, all of which are fresh on the same day. Consider ~
Some medicines are actually cheaper than those sold in China, such as mosquito bites and eye drops, which have many explosions and are sold in ordinary drugstores. You can bring some common medicines, cold medicines, diarrhea medicines, and so on.
that's all I can think of, I hope to adopt it ~
