Japanese Toilets: The World's Most Advanced Bathrooms

Welcome to the Future of Bathrooms

If there's one thing that universally shocks first-time visitors to Japan, it's the toilets. Japanese toilets — known as washlets — are a marvel of engineering that will make you question everything you thought you knew about bathroom technology. Heated seats, bidet sprays, sound effects, and automatic lids are just the beginning.

The brand you'll see everywhere is TOTO, the company that basically invented the modern smart toilet. Their Washlet line has been standard in Japanese homes and public restrooms since the 1980s, and the technology has only gotten more impressive.

Features You'll Find on Japanese Toilets

Here's what a typical Japanese toilet offers — even in a random convenience store or train station:

• Heated seat — adjustable temperature, a blessing in winter
• Bidet spray — with pressure and position controls
• Front wash — separate spray for different needs
• Warm air dryer — yes, a built-in dryer
• Sound button (音姫 / otohime) — plays flushing sounds for privacy
• Automatic lid — opens and closes as you approach
• Deodorizer — built-in air freshener
• Night light — gentle illumination for midnight visits

High-end models in hotels even have self-cleaning nozzles, health monitoring, and automatic flushing. Some play music. No, really.

How to Use the Buttons

The control panel can be intimidating at first, with all its Japanese labels. Here's a quick guide:

• おしり (oshiri) — rear spray/bidet
• ビデ (bide) — front wash
• 止 (tome) — stop
• 流す (nagasu) — flush
• 水勢 (suisei) — water pressure adjustment

Many tourist-facing restrooms now have English labels or pictograms. When in doubt, the big button flushes, and the panel on the wall or armrest controls the smart features.

Traditional Toilets Still Exist

You may occasionally encounter a squat toilet (和式 / washiki) in older buildings, train stations, or rural areas. These are floor-level toilets you squat over. They're becoming rare but haven't disappeared entirely. If you see a row of stalls, look for the one marked 洋式 (Western-style) if you prefer a seated toilet.

Public Restrooms Are Free and Everywhere

Unlike many European cities where you might pay €0.50-1 to use a public toilet (see our Is Japan Expensive? comparison), restrooms in Japan are always free. You'll find them in train stations, convenience stores, department stores, parks, and temples. And they're almost always spotlessly clean.

This is a huge cost saver compared to countries where bathroom access is restricted. It also means you don't need to budget for restroom access — one less thing to worry about on your budget trip.

Want to Take One Home?

TOTO Washlet seats can be purchased starting around $300-500 and installed on any standard Western toilet. They make surprisingly popular souvenirs (well, shipped home at least). You can find them at electronics stores like Bic Camera or Yodobashi Camera, sometimes with tax-free pricing for tourists. You can pick one up while shopping at 100-yen shops for other travel essentials.
