Ashi-yu: A Different Way to Enjoy Japanese Onsen Culture
A common highlight of Japanese travel itineraries and frequently featured in anime or other media, Japan’s “onsen” hot springs and traditional “sento” public baths are a beloved part of the local culture, offering true relaxation to residents and visiting travelers alike. What many nervous sightseers might not realize, though, is that a bath in Japan doesn’t always have to be for your whole body! Ashi-yu (足湯) are Japanese foot baths or foot spas, designed to help you soak away tired feet and sore muscles – perfect after a long day of sightseeing – and wipe away the stress of a long flight to Japan.
Ashi-yu are a treat, and they’re also extremely convenient. Scattered throughout onsen towns and occasionally found in places like train stations, cafes, or even in airports, many footbaths are free to use, meaning any passerby can spend a few minutes relaxing at the ashi-yu before continuing with their day. Plus, you don’t have to strip down or change to use a Japanese footbath! A quick visit to a Japanese ashi-yu is ideal for travelers strapped for time, or any shy bather interested in experiencing a Japanese onsen without stripping down and getting naked in front of others.
The Benefits of Japanese Ashi-yu Foot Baths
Japan’s foot baths aren’t just a convenient alternative to a full-body onsen soak – they’re considered especially beneficial by many in Japan. On top of being a relaxing experience, ashi-yu are often recommended because they warm you from the feet up!
Dipping chilly toes into the hot onsen water is said to help with circulation, heating your whole body without sapping your energy. Japan’s strong bath-taking culture means that locals are especially aware of the potential dangers of bathing (especially after drinking), and worry about getting dizzy from the intense heat of the water, but a good foot bath will warm you up while avoiding those problems entirely. Japanese people like to say that keeping your feet warm and your head cool is good for your health, which would make the ashi-yu a helpful health tool!
Where to Find the Best Ashi-yu in Japan
Japan’s Largest Ashi-yu Foot Bath
Tucked away in the picturesque rural area of Nasu-Shiobara, in Tochigi Prefecture, Yuppo-no-Sato has one of the largest footbaths in Japan, called the “Ashi-yu Kairo” (足湯回路). The name literally means foot bath corridor, as this unique foot bath runs along the edge of a large, circular building, with a circumference of about 60m (almost 200ft)! Under the warm wooden roof, visitors can walk along the corridor to enjoy a series of unique experiences, as different areas are heated to different temperatures and the stones underfoot are laid out in different patterns!
An Ashi-yu for Shogi Lovers
The city of Tendo, Yamagata is known for producing the pieces used to play shogi, a strategic board game sometimes called “Japanese chess.” So it’s only fitting that the city also has a footbath shaped like a shogi chess piece! Filled with hot spring water that flows from Tendo Onsen, this ashi-yu can be found at Tendo Onsen Michi-no-Eki, a “road station” (rest stop) along the highway leading into Japan’s northern Tohoku region. If you’re planning a road trip in Japan, you’ll want to add this foot bath as a stop.
A Rare Steam-Based Footbath
In both English and Japanese, the terms “foot bath” and “ashi-yu” imply the action of dipping your feet into hot water, but this unusual ashi-yu in southern Japan offers a slightly different experience. To find it, head down to the island of Kyushu, get yourself to Oita Prefecture, and take a moment to visit the city of Beppu – one of the most famous onsen destinations in Japan. As a result of all the geothermally heated spring water flowing both below and above ground, warm hot spring steam is everywhere in Beppu, and this foot bath takes advantage of that feature by using the water vapor instead of normal water. They actually call it an “ashi-mushi” (足蒸し/”foot steam”), and you can try gently steaming your own feet by lowering them into the wooden structure used to keep the heat in. It almost looks a little ominous, but don’t worry, the experience is so relaxing that you won’t even worry if your feet come out of the box looking lobster red from the warmth!
Enjoy Japan’s Onsen Culture Every Way You Can
Whether you’re ready to move on to the luxurious full-body baths of Japan’s many onsen, or you’re happy warming your feet in the ashi-yu, Japan’s hot springs are waiting!
