Can Japanese people stay at this hotel in Pudong International Airport Terminal Building without entering the customs, that is, without clearing customs due to a transfer? Does this hotel also require clearing customs?

If Japanese people do not enter the country, that is to say, they cannot go through customs due to transit, they usually cannot stay in the hotel in the Pudong International Airport terminal. This type of hotel is usually used by incoming passengers and international passengers who are in transit but do not need to go through customs. If you are just transiting and not going out of customs, you are generally not allowed to enter this type of hotel. Relevant airport and customs regulations need to be observed.
