The use of toilets varies from country to country. Japan has a well-developed sewage system, and toilet paper dissolves in water. When using a flush toilet, be sure to flush used toilet paper down the toilet, rather than disposing of it in the trash.
There are various ways to flush the toilet, such as pushing a lever, pressing a button, or holding your hand over a sensor on the wall or back. If you don't know how to flush the toilet, calmly examine the area around the toilet bowl and the walls of the toilet. There may be instructions on how to flush.
