The Spread of the WASHLET® in Public Settings <Japan>
In Japan, the penetration of heated bidet toilets in regular households*3 reached 80.3% (2021), and there isbroad uptake as housing equipment. In terms of public restrooms, since 2015, based on the concept of"making Japan a showroom for the world," the installation of WASHLET units in the public restrooms ofcommercial facilities, public transportation facilities, accommodation facilities and elsewhere wasaccelerated, in an effort to promote experiences using WASHLET units among foreign visitors to Japan.
WASHLET units are also increasingly used in the various facilities, including the restrooms of offices, hospitals
and schools, and over the last decade, the number of WASHLET units shipped in Japan has increased by 1.2times.

Reducing the Size of Components to Help Improve Design Qualities
The first WASHLET in 1980 began with three functions: (1) Rear cleansing with warm water, (2) Rear drying withwarm air, and (3) seat warming. In the years since, the number of components has increased each time various
new functions to make toilets cleaner and more comfortable have been added, and today the units can use up
to 400 individual components.
Meanwhile in overseas markets there has been a strong trend towards strong design qualities in plumbing
equipment, and heated bidet toilets are no exception. Especially in the current European market which is theleader in worldwide design, there is a strong trend towards "thinner" products. TOTO, which has championed
the sophisticated fusion of technology and design, searched for ways to make its product thinner without
removing functionality.
Making the product thinner meant reducing the "height" of WASHLET unit. WASHLET component which thegreatest height is the nozzle when stowed.
Previously the height of the nozzle was controlled byextending and retracting it in two stages like a fishing rod, but
it was the "curved nozzle" that was developed to make it eventhinner.
The development of a nozzle that has a curved shape with nostraight lines and which also extends and retracts in two stages
required designers to fundamentally revisit the molds thatformed the nozzle components and overcome a host ofchallenges, including miniaturizing the motor and innovating
the cable rack that extends and retracts.

The nozzle extends in two stages

The curved nozzle, which reduced unit height by about 30% compared with previous models, was first equippedin WASHLET RW ("RW," hereafter), which was not released in Japan. The product was launched in the European
market starting November 2019. The RW was very well received in the European market and has become thebestselling model despite being the highest grade product offered.
NEOREST LS standard global model that went on sale in August 2022 is also equipped with the curved nozzle,
which has contributed to its elegant design. In addition, by revising other components as a whole in the unit,
such as reducing the size of the ceramic heater that produces warm water by around 20%, WASHLET continues
to evolve into something thinner and more compact.
