How to use a Japanese toilet: features, buttons and instructions

A Japanese toilet can look surprisingly high-tech to visitors from Australia. Many models combine a conventional toilet with a bidet seat, heated seating, automatic flushing, deodorising fans and several adjustable water settings. The controls may be printed in Japanese, but the symbols are usually consistent enough to understand after a few minutes.

These toilets are common in homes, hotels, department stores, shopping centres and railway stations across Japan. You may find a basic washlet in a small café bathroom or a feature-rich model in a Tokyo hotel. The design varies, yet the main functions work in much the same way.

For Australians used to dual-flush toilets in Sydney, Melbourne, Brisbane or Perth, the biggest difference is the number of controls. The safest approach is to identify the flush, stop and water-pressure buttons before trying any spray function.

Identify the main controls

Look for the flush button first. It may be mounted on the wall, placed beside the toilet, or built into a control panel near the seat. Common Japanese labels include 大 for a large flush, 小 for a small flush and 流す for flushing. Some toilets flush automatically when you stand up.

The most important button is usually marked 止, meaning “stop”. Press it whenever you want to end the water spray. A power symbol, often shown as a circle with a line, may switch the seat functions on or off rather than flush the toilet.

Many panels use simple icons instead of words. A seated figure with a rear spray indicates the standard bidet wash, while a feminine figure or front-facing spray symbol indicates a front wash. If the controls are unfamiliar, wait until you are seated before activating anything.

Adjust the wash gently

Sit fully on the seat because many Japanese toilets have a sensor that prevents the spray from operating when nobody is sitting down. Press the rear or front wash button once, then allow a moment for the nozzle to extend and the water stream to begin.

Start with the lowest water pressure and a moderate temperature. The spray position can usually move forwards or backwards using arrow buttons. Some models offer pulsating or oscillating water, which can make cleaning more comfortable but may feel unexpected at first.

Use the stop button before standing. Avoid touching or pulling the nozzle, and do not place toilet paper into any opening other than the bowl. The nozzle normally rinses itself after use, and some models have a separate “nozzle clean” function for maintenance.

Explore comfort and hygiene features

A heated seat is one of the most noticeable features, particularly during winter in northern Japan. The temperature control may show several bars or a thermometer symbol. Some public toilets disable heating to reduce electricity use, while hotel rooms often allow guests to adjust it.

A warm-air dryer may be labelled 乾燥 or shown with a fan symbol. It can reduce the need for toilet paper, although drying may take longer than expected. Many people use a small amount of paper first and then activate the dryer.

Other settings include a deodoriser, a lid that opens automatically, a soft night light and a privacy sound. The sound feature, sometimes represented by a musical note or speaker symbol, masks bathroom noises. In busy public facilities, it is often used to avoid wasting water through repeated flushing.

Read Japanese labels and icons

A few words are especially useful when using a toilet in Japan:

止 means stop.
おしり means rear wash.
ビデ means bidet or front wash.
乾燥 means warm-air drying.
流す means flush.
水勢 means water pressure.

Colour coding can help, although it is not universal. Blue buttons often control water, pink or red buttons may indicate the front wash, and grey buttons commonly operate the flush or stop function. Treat the stop button as your first reference point when unsure.

In airports such as Narita and Haneda, instructions are often bilingual. Smaller stations, rural restaurants and older public toilets may have fewer English labels. A translation app can identify Japanese text, but it is better to memorise the symbols for stop, flush and rear wash before travelling.

Use public toilets respectfully

Japanese bathrooms are generally clean, but etiquette still matters. Keep toilet paper in the bowl unless a sign specifically says otherwise. Some older facilities may have a squat toilet alongside Western-style cubicles, while accessible toilets usually provide more room and clearer controls.

Do not test every button in a crowded public bathroom. Water pressure can be surprisingly strong, and an unexpected spray can create a mess. Leave the seat and surrounding area dry, dispose of sanitary products in the provided bin, and follow signs about changing tables or multi-use facilities.

Australian travellers may notice that bidet seats are less common in everyday public bathrooms at home, although premium bathrooms and the Australian bidet-seat market are growing. In Australia, accessible toilet design is also shaped by the Disability Discrimination Act 1992 and related standards, while Japanese facilities may use different layouts and symbols.

Install one safely in Australia

A Japanese toilet seat bought in Japan is not automatically suitable for an Australian bathroom. Japan generally uses 100-volt electricity, while Australian homes use about 230–240 volts. Never plug a Japanese electrical toilet seat directly into an Australian outlet without confirming that the product is designed for local voltage and approved for use.

Water connection sizes, plumbing fittings and electrical protection can also differ. An electrician or licensed plumber should check the installation, especially in a wet bathroom. Australian electrical safety rules and water-efficiency requirements apply to products sold and installed locally.

For a simpler upgrade, choose an Australian-market bidet seat with local instructions, warranty support and compliant electrical components. A non-electric bidet attachment may avoid some electrical issues, but it still needs a secure plumbing connection and correct backflow protection.

Before buying, check these practical details:

Australian voltage compatibility and certification
Suitable toilet bowl shape and seat dimensions
Access to a nearby power point with safety protection
Water inlet and plumbing compatibility
Local warranty, repairs and replacement parts

Once you know the essential symbols, operating a Japanese toilet is straightforward: sit down, choose a gentle wash, adjust the position if needed, stop the spray, dry, and flush. Save the key Japanese labels on your phone before your trip, then try the controls calmly when you first encounter one in Japan.
