What should I pay attention to when traveling to Japan?

1. Notes for entering Japan: You only need to declare your personal belongings orally. If the customs officers think that the content and quantity are reasonable, the personal belongings carried by passengers will not be taxed. Duty-free items and their limits are: 500 grams of tobacco; 400 cigarettes or 100 cigars; 3 bottles of wine (760 cc); Two ounces of perfume, except the above duty-free goods, the actual total price of the purchased goods does not exceed 200,000 yen, and there is no need to pay taxes. It is inconvenient to change money in Japan, so you must change money at a foreign currency exchange bank or other legal currency exchange offices. In addition, you must show your passport. However, the Japanese bank exchange business is only conducted between 9 am and 3 pm. In addition, banks are closed all day on Saturdays, Sundays and major holidays. So money can only be exchanged in hotels, but it is a little more expensive than bank exchange. 3. Pay attention to etiquette: 1) Don't litter and spit (Japan is very clean) 2) Don't run the red light 3) After shopping, the waiter will say thank you, you can respond, but at least smile and nod.

For example, the number "4" sounds like death, and "42" sounds like a dead verb, so hospitals generally don't set rooms and beds for 4 and 42. Users are also prohibited from using "42" on their mobile phones, and prisons generally do not have cell 4. "13" is also a taboo number. Many hotels don't have "13" floors and "13" rooms, and Haneda Airport doesn't have "13" apron. Don't say anything unlucky, such as going, returning, leaving, breaking, thin, cold, shallow, ruined, heavy, broken and broken, at weddings and other festive occasions.
