The water used by Japanese bidets is typically warm, which makes for a more comfortable experience.

How Was Japanese Bidet Discovered?

Bidets have been around for centuries, but the first electronic bidet was invented in Japan in the 1960s. These early models were simple and consisted of a basic spray system. However, as technology advanced, so did the bidet. In the 1980s, Japanese companies began adding more features to their bidets, such as heated seats and air dryers.

Today, Japanese bidets are some of the most advanced in the world. As of 2016, 81% of Japanese households use bidets, more commonly called washlets. Washlet is basically the brand name of Toto, the number one manufacturer of Japanese toilets. They come with a range of features that make them both hygienic and comfortable to use. Japanese bidet manufacturers are constantly improving their products, adding new features and technologies to make the bidet experience even better

How to Use Japanese Smart Toilets

Once you understand the functions of each button on a Japanese toilet, using it will be easy. Here are some important points to note:

1. Automatic Sensors

Many restrooms in Japan, especially those with newer toilets, have automatic sensors for various functions. For example, a sound simulator may activate when someone enters the cubicle, even without pressing any buttons. Be careful not to confuse it with the regular flush button, as the sound simulator is often attached to the wall. Additionally, some modern toilets automatically flush as soon as you get off the seat. Finally, don’t be surprised if the toilet cover automatically rises when you enter the cubicle as even newer models will have a motion sensor for that.

2. Emergency Call Button

Some toilets are equipped with an emergency call button, usually located next to the flush button. This button is intended for use by people with disabilities or in case of sudden illness while on the toilet. It is labeled as “yobidashi” and should only be used in emergencies. It is often colored in red or yellow, which can be misleading, as many people may mistake it for the flush button.

3. Locating the Flush Button

Depending on the toilet model, the flush button may be located on the side of the tank, replaced by a push button, a motion-control sensor, or integrated into the main control box mounted on the wall. Take care not to confuse it with the button for the water simulator sound or the emergency call button. Look for labels such as 流す, 大, or 小 to identify the flush button.

4. Flushing Toilet Paper

In Japan, it is customary to throw toilet paper directly into the toilet after use. However, it is important to ensure that you are using actual toilet paper and not paper towels or facial tissues, as these can cause clogs. Other items such as sanitary pads or wrappers should be disposed of in a small trashcan inside the cubicle.

By following these guidelines, you can confidently and effectively use a Japanese smart toilet.

Western vs Japanese Toilets

Japanese bidets are often compared to traditional Western toilets, which use toilet paper to clean the private areas after using the toilet. While both methods are effective at cleaning, bidets offer several advantages over traditional Western toilets.

Bidets provide a more thorough and hygienic cleaning experience than toilet paper. They use water to clean their private areas, which is more effective at removing bacteria and other harmful substances than dry toilet paper.

Bidets are also more environmentally friendly since they reduce the amount of toilet paper used. This is not only good for the environment but can also help save you money in the long run.

Finally, bidets are more comfortable to use than traditional Western toilets. They come with heated seats, which is especially beneficial during cold winter months. Some models even come with air dryers and deodorizers, which can make for a more pleasant bathroom experience.

It’s gotten to the point where even foreigners who have lived in Japan for a long time claim that they could never go back to using just toilet paper in their bathrooms!
