Can I smoke in a non-smoking room in Japan?

If it is a non-smoking room, there will be an alarm device (included in the bathroom of the room)! If there is smoke, you call the police! If you call the police for smoking, you will be fined! This has been tried by my compatriots! If you want to smoke, you can ask when you book a hotel order. Usually some hotels are divided into floors, and some floors are smoking rooms! If the order has been established, you can try to communicate with the hotel mailbox and bring it up when you get to the hotel! Usually the hotel will try its best to help you!
