What is the check-out time of Japanese hotels?

The check-out time in Japan is 10 in the morning, and the earliest check-in time is 15 in the afternoon. This is completely different from China. Domestic hotel members can check out on 14, and if there is a clean room, they can check in earlier than 14, which is very humanized. Because if the guest wants to catch the train, he will naturally check out early, but if it is an afternoon train, staying for two more hours will increase the cost, and if the cost of this period is exempted, the guest will feel very cost-effective and book it next time. Japanese hotels are not as good as domestic hotels because they are convenient for themselves. Because guests have five hours of cleaning time after checking out, it is convenient for them, but it is inconvenient for some people who go by car in the afternoon. And the money paid by the guests is the room fee for a whole day. Even if they 15 checked in, they would only have less than 19 hours of rest the next day, which is too arrogant. I also know that there is a domestic brand hotel that can check out 15 for free. I am very satisfied and will stay in this hotel next time.
