A Japanese toilet company TOTO has a showroom in Shinjuku 新宿 Tokyo. Many recent model toilets are displayed there. This place is like a toilet museum. It is called TOTO Tokyo Center Showroom (TOTO東京センターショールーム).
WASHLET is TOTO's brand name and means electrical shower toilet seat (bidet).
You can also see the company's bathtubs and kitchens in the same showroom.
I think it would be fun for international tourists who are interested in the newest Japanese household equipment.
There are real restrooms (toilets) outside the showroom.
There are many buttons beside the toilet seat. Don't worry how to use.
After you go to the toilet, simply you need to use just these 4 buttons on the picture below.
It is located near Shinjuku 新宿 Station. This place is on the 7F and 8F of the building.
Business hours: 10:00 am - 5:00 pm
Wednesdays are closed except pre-national holiday.
* It is closed between April 30 and May 1, 2019.
It is located in Narita 成田 International Air Port.
