What Are Japanese Toilets?

A Japanese toilet or smart toilet, as it’s often referred to, is a toilet built with smart technology.

Put simply, this means smart toilets can interact with their user via remote control access.

With a press of the button, you can flush, spray and dry. As the name suggests, Japanese toilets originated in Japan.

Commonly known in Japanese as “washable” or as “warm-water cleaning toilet seats”.

This high-tech toilet is the world’s most advanced toilet system.

What do Japanese toilets do?

Japanese Toilets have a vast variety of functionalities, that aim to make your trips to the loo, that little bit easier. The Japanese toilet has water and air drying setting that can be adjusted to suit the user’s preferred temperatures – impressive, right? Temperature preferences can be saved ready for your next visit to the bathroom. For those of you who are unsure about the Japanese toilet functionalities, here are some of the toilets main features:

  • Spray wash
  • Air drying
  • Stop operation
  • Deodorising
  • Self clean
  • Night light
  • Energy saving
Japanese Toilet Features

Spray Wash 

The spray wash function makes sure you feel clean after going to the toilet. There is a rear wash or female wash for an extra fresh feeling. You can adjust the water temperature to suit your personal preference.

Air dryer 

After the spray wash has completed the Toilet will then move onto the air dryer function. Again, the air dryer allows you to choose the perfect temperature.

Stop operation

The stop operation function comes in handy for those days when you’re in a rush. You can use the stop operation button to stop the washing and air-drying functions, by tapping the stop button.

The deodoriser will make sure your toilet and bathroom is always smelling fresh. The deodoriser will release a beautiful fragrance for 1 minute after use – giving you a toilet that’s always guest ready

Automated clean

Japanese Toilets have automated cleaning assistance. If the toilet is not used for more than 72 hours, the tank will clean itself – pretty good, huh?

Self clean

Night light

You can use the Japanese Toilet night light to guide you to the loo in the middle of the night. This is a great way to spare your eyes, rather than burning your retina by turning on your main light, use the night light functionality. Not only does this look pretty special once lit up, but the night light will adjust its light/darkness levels depending on its environment.

The Japanese Toilet wouldn’t be complete without an energy-saving aspect. When not in use, you can keep your smart toilet on standby to save some extra pennies and more importantly, help the environment.

There are plenty of benefits to having a smart toilet, as we listed above but that doesn’t mean they’re always the right option for you. After all, they are quite costly. However, having a Japanese toilet in your home will make life easier.

If you’re looking for something environmentally friendly, that needs little maintenance and looking after this could be the toilet for you. Smart toilets flush using the right amount of water, every single time. This reduces the amount of water used on each flush.
