What should I pay attention to when traveling to Tokyo? What should I bring?

This reminds me of the different Japanese rain customs I saw in China. Hope this helps. Shopping Tip: All items in Japanese stores have a price tag. Even the bargain won't be stingy, so don't be stingy. Don't haggle. Food stores in Japan generally don't allow you to try it. When trying on clothes and shoes, please say hello to the store clerk first. You can speak Chinese and make gestures. The store clerk will take you to the fitting room. If you are wearing makeup, use a store-prepared mask when trying it on to prevent it from staining your clothes. Please ask the store staff for usage. Traffic Tips: Please keep quiet when taking trams and buses. Talking loudly can get in the way of others. In principle, the use of mobile phones in the car is prohibited. Please get off the bus before getting on. Please avoid crowding when getting on the bus. The Japanese way of waiting for a bus is to line up consciously and queue-jumping is prohibited. Tips: Hot springs are different from swimming pools. They are places for bathing. So please don't take a bath without clothes on. It is also forbidden to put towels on when taking a bath. Before taking a bath, be sure to wash yourself with hot water. Gesture: The Chinese give a thumbs up as a sign of praise, while in Japan it means no appreciation from men and boyfriends. In China, holding out the little finger means bad, while in Japan it means girlfriends and women. When Japanese people meet, they usually bow to say hello instead of shaking hands. Garbage placement: In Japan, everyone should not litter everywhere. Be careful not to drop it on the floor while eating. Trash must be thrown into the bin. In central Tokyo, many places do not have trash cans for safety reasons. You'd better take your trash back to the hotel. Toilet Tip: Japanese toilet paper dissolves directly in water. So in Japan, used toilet paper can be flushed directly into the toilet without being thrown into the trash. In addition, to avoid fire hazards, smoking is strictly prohibited in toilets and elevators. Smoking: Smoking is prohibited in general places except designated smoking places. Smoking is not allowed in restaurants except at smoking seats. Smoking on the road will result in a fine. Don't throw cigarette butts everywhere. Please put it in a portable ashtray (available at convenience stores) and bring it back. Taboos: Talking loudly, staring at others, putting your hands in your pockets, and pointing fingers are considered disrespectful. It is extremely rude to take or put a business card out of your back pocket. Avoid taking photos of three people side by side because the person standing in the middle is suspected of being controlled by others. When visiting Japanese, you should make a reservation first. If you're not invited, don't. Don't go in and don't sit down. It is taboo to peek into the bedroom and kitchen; do not look through anything except books and newspapers. Kissing, hugging and chewing gum alone are taboo in public places. Don't hold your chopsticks tightly when eating vegetables, and don't mix vegetable soup with rice, as this is how you feed cats and dogs. Take off your shoes before entering the house; change your socks frequently (it's best to wear cotton socks to avoid the smell caused by sweaty feet) and don't wear out your socks. Keep cuffs clean. Avoid four and nine when giving gifts because in Japanese four is death and nine is bitterness.
