The rise of the Japanese toilet

In 1982, a peculiar commercial aired on televisions across Japan.

- RIVER AKIRA DAVIS KIUKO NOTOYA

An actress in a pink floral dress and an updo drops paint on her hand and futilely attempts to wipe it off with toilet paper. She looks into the camera and asks: “Everyone, if your hands get dirty, you wash them, right?”

“It’s the same for your bottom,’ she continues. “Bottoms deserve to be washed, too.”

The commercial was advertising the Washlet, a new type of toilet seat with a then-unheard-of function: a small wand that extended from the back of the rim and sprayed water up. After its release, Toto, the Washlet’s maker, was deluged with calls and letters from viewers shocked by the concept. They were also angry that it was broadcast during evening prime time, when many were sitting down for dinner.

Four decades later, Japan has overwhelmingly accepted Toto’s innovation. Washlet-style bidets, sold by Toto and a few smaller rivals, are a common feature in Japan's offices and public restrooms and account for more than 80% of all household toilets, according to government surveys.

Toto now sees a similar shift emerging in the United States.

After decades of trying to persuade leery American consumers of the merits of bidets, Toto Washlets have become something of a social phenomenon — popping up on social media tours of five-star hotels and celebrity homes. The comedian Ali Wong devoted a segment of her 2024 Netflix special to Toto’s “magical Japanese toilet.” In 2022, the rapper Drake gifted four Totos to the artist DJ Khaled.

An industry report last year showed that more than two in five renovating homeowners in the United States are choosing to install toilets with specialty features, including bidet toilet seats. Toto’s profits in its Americas housing equipment business have grown more than eightfold over the past five years — and the company has its sights on expanding even more.
