Do Japanese tourist hotels need to issue invoices? Can you get a refund?

The invoice should be available, but it may not be of any use to you. Tax refund is definitely not allowed. Simply put, everything you buy in Japan can be refunded as long as it meets a big principle. The principle is: articles used or consumed after reaching a certain amount and taken out of Japan. In other words, eating in Japanese restaurants, buying lunch in convenience stores, buying drinks in vending machines, watching movies, or staying can't be refunded.
