Why do some Japanese hotels have to pay taxes and some don't? Is it a level problem?

In Japan, all consumption is taxed, but whether I tell you or not, regardless of the level. When you go to a convenience store to buy things or go to a restaurant to eat, you can see that a commodity has two prices, one is the price including tax, and the other is the naked price of the commodity, which will clearly tell you how much tax is included. If you look at the bill carefully, the tax amount will usually be written on it.
