The Fascinating World of Japanese Toilets in Floor

When it comes to toilets, Japan certainly takes it to the next level. One unique feature of Japanese toilets is the in-floor type, where the toilet is installed directly into the floor.

This may seem strange to those who are used to the traditional pedestal-style toilets, but in Japan, it is a common and preferred choice for many. In this article, we will explore the reasons behind the popularity of Japanese in-floor toilets and how they work.

What Are Japanese Toilets in Floor?

As the name suggests, Japanese in-floor toilets are installed directly into the floor. This means that the toilet bowl is level with the floor, and there is no need for a pedestal or raised platform. The toilet seat is usually located a few inches above the bowl and can be heated for comfort.

The in-floor toilet design is unique to Japan and can be found in many homes, public restrooms, and hotels. It is also commonly known as the “washiki” style toilet.

Why Are Japanese In-Floor Toilets So Popular?

There are several reasons why Japanese in-floor toilets are so popular in Japan. Firstly, they are more hygienic than traditional pedestal-style toilets. This is because there are no crevices or gaps between the toilet and the floor, which can accumulate dirt and bacteria.

Secondly, Japanese in-floor toilets are more comfortable to use. The level design means that there is no need to squat down or balance on a raised platform, which can be difficult for some people, especially the elderly or those with mobility issues.

Thirdly, the in-floor design is more aesthetically pleasing. It gives the bathroom a sleek and modern look, and there are no unsightly pipes or fixtures visible.

How Do Japanese In-Floor Toilets Work?

Japanese in-floor toilets work in a similar way to traditional toilets. The main difference is that the waste pipe is located directly beneath the toilet bowl instead of being concealed within the pedestal.

When you flush the toilet, the waste is transported through the pipe and into the sewer system. Many Japanese in-floor toilets also have bidet or washlet functions, which use a stream of water to clean the user after they have finished using the toilet.


Q: Are Japanese in-floor toilets expensive?

A: The cost of a Japanese in-floor toilet varies depending on the brand and features. However, they tend to be more expensive than traditional pedestal-style toilets.

Q: Are Japanese in-floor toilets difficult to install?

A: Installing a Japanese in-floor toilet requires some expertise and knowledge of plumbing. It is recommended to hire a professional plumber to ensure that the installation is done correctly.

Q: Can I retrofit my bathroom to accommodate a Japanese in-floor toilet?

A: It is possible to retrofit your bathroom to accommodate a Japanese in-floor toilet, but it may require significant renovations. It is best to consult with a professional plumber or contractor to determine the feasibility and cost of such a project.


Japanese in-floor toilets may seem unusual to those who are not familiar with them, but they are a popular and practical choice in Japan. They are more hygienic, comfortable, and aesthetically pleasing than traditional pedestal-style toilets. If you are considering upgrading your bathroom, a Japanese in-floor toilet may be worth considering.
