Why would anyone feel the need to write about toilets? Well, when in a foreign country and you get the sudden urge to go, you will need to be able to understand two basic essentials – 1-where to find a toilet and 2-how to use it. Simple right? Not exactly, especially in Japan where the variations of toilets ranging from the Japanese squat toilet to Japanese high tech toilets can be quite confusing. So here are my Japan toilet tips and plenty of pictures of toilets to help you navigate the minefield of Japanese toilet etiquette.

Japanese toilet signage

While signs for locating a washroom or toilet are fairly universal in Japan, there are variations. 

One sign in a zoo caused me some concern as I wasn’t quite sure if I was going to the toilet or the lion’s enclosure!

There may also be a sign for a baby (or maybe it’s a sumo wrestler)? Both seem to wear similar clothing. 

Many toilets have rather convenient baby holders inside the cubicle where you can put your baby whilst you ablute. 

This is a great idea as long as baby fits the weight and size restrictions. Does this remind you of the hand luggage procedure in the airports?

Talking about babies, there are cultural differences you need to be aware of.

Apparently, women can take their baby into a toilet and can change a diaper. But men may only be allowed to take their baby into the toilet. Changing a nappy is not something Japanese men want to be caught doing in public, I gather!

Japanese washroom slippers

Toilets in ryokans (traditional inns usually with a Japanese onsen) have a toilet etiquette you need to be aware of.

Just as shoes are not worn inside a house – and certainly not in a room with a tatami mat floor – there are certain types of slippers to be worn once you enter a toilet.

A good clue is these are usually the ones labelled “Toilet”.

In fact, this system is quite useful as not all toilets in Japan have signs to indicate that they are occupied.

If there are no slippers visible for you to step into then you can assume that all the toilet cubicles are occupied. 

How to use a Japanese toilet 

Stating the obvious? Not so in Japan. Let’s start with the exterior design.

Sometimes, finding the toilet block can be a bit of a challenge. Especially when an artistic architect in Japan comes up with an out-of-the-box idea on how a public toilet should look. It can be easy to miss so think outside the square.

Now to the intricacies of actually using a toilet in Japan. In Japan, there are two basic styles, the Western toilet and the Japanese toilet.  

Using a Japanese style toilet

Japanese style toilets are usually in the floor. Do practice the art of aiming whilst crouching or you will soil your undergarments. Strong thighs and gluteal muscles are essential.

This in-floor style of Japanese toilet is also found in the Japanese trains, which are one of the main modes of travel in Japan. So you’re likely to find yourself squatting while travelling through Japan. 

The shinkansen or ‘bullet’ train has a few extra modifications for dealing with ablutions.

Whilst travelling at 300km/hr, it is essential to hang on to the ‘sissy bar’ whilst peeing with high G-forces applied.

Also, be forewarned of its high-powered vacuum suction when flushing. It’s based on the same theory that high speeds are the fastest way to move things from A to B. Very impressive!

Western bidet toilet seat

The instructions on how to use a bidet toilet seat will be in Japanese but the pictures are helpful.

The Japanese twist on the western toilet is that most Japanese toilets are also bidet toilet seats.

Using a Japanese bidet can be a little mind-boggling at times. There are simple straightforward bidets. Then there are Japanese bidets that do everything except cook the family roast.

There are bidets that come with a bottom-wash button, with variations of water jet strength, a rather curious ‘lady’ button (you’ll have to test that one out yourself) and then there’s the power deodorizer button.

These Japanese bidets also come with a variety of sounds triggered by sitting on the toilet.

Mozart on the toilet?

So don’t be surprised to be serenaded by a waltz or a Mozart concerto or the gentle sound of a tickling waterfall while you are sitting on the throne. 

The seat may be heated or not heated. I personally find heated toilet seats in public toilets rather off-putting as it conjures images of well-endowed rear-ends belonging to the toilet’s previous users.  So you might want to think twice before using a heated toilet seat. 

Sometimes the flush mechanism may not be obvious and in some toilets, there’s a sensor-operated light in a toilet wall that is not as obvious either. Some Japanese toilets have subtle buttons.

I’ll admit the first time I used Google Translate in Japan was in a restaurant toilet while trying to work out which button actually flushed the toilet. It gave me a helpful choice of a ‘small’ or ‘big’ flush upon translation of the various Japanese symbols.

A lever style is fine but it may flush and activate a tap on top of the cistern. This one personally stymied me as I kept pressing the flush in an attempt to stop the tap running, which just kept on running…

Toilet paper and how to use it

This does need a mention so you won’t be disappointed in the Japanese single ply paper. Double or triple ply, super soft or aloe vera impregnated paper is a luxury that the Japanese do not seem to have an appreciation of. 

Also worth noting is that the perforated toilet paper we may be accustomed to is replaced by Japanese toilet rolls with no perforations.

This results in very ragged, torn, irregular ends to a toilet roll after you have wrestled to tear off your portion. This can be a bit puzzling to most tourists as Japanese are generally very neat and tidy, even in the toilet.

However occasional toilets have toilet roll holders with toothed serrations that help you to create a neat torn off roll. Perfect. Don’t forget to put said used paper down the toilet and not in the wastebasket.

If you see a small phone-sized panel on the wall, it’s probably an alcohol dispenser. Follow the instructions to clean the toilet seat after you have used it.

So as you have finally mastered the intricacies of the Japanese toilet, and your Japanese holiday comes to a sad end, you may want to purchase your own Toto bidet at the Duty-Free shop in the airport. Bargain prices for a great souvenir!
