Japan has a bathing culture like wow. Going to onsen, or hot springs, is a rite of passage for every youngster, and kids are taught from an early age how to do public bathing appropriately, often by their grandparents. Getting starkers as a family is as natural in Japan as hopping into the shower. Believe it.

Given that Japan is basically built on a string of volcanoes, it’s no shock that onsen are the pinnacle of bathing culture. Not only do onsen heat you up and clean you, but the waters are said to have many restorative powers due to the minerals in them. Claims about everything from alleviating diabetes and cancer to healing problem skin and backaches run rampant.

Onsen vs. Sento

Onsen means “hot springs” so by definition onsen are fed by natural spring water. A sento is a public bathhouse, which may be filled with natural spring water but more often than not isn’t.

Sento used to be everywhere, before baths came standard in housing. Still people use them, perhaps for a more leisurely soak than a shared bathroom at home would allow. They also function as community hubs. Importantly, sento tend to be pretty cheap, costing only a few hundred yen, whereas onsen tend to cost more.

Bathing Ground Rules

It may seem a daunting endeavour, but once you know a few basics, onsen-relaxation is a very manageabe and even enjoyable adventure.

What to Bring

  • Towels: Most places will rent or include towels, but if it’s a new spot or you’re unsure, its a good idea to bring your own. A larger bath towel for drying and a smaller wash towel or “modesty” towel that you can take into the bathing area and discreetly hold in front of your wobbly bits if so desired.
  • Soaps: While most facilities will offer body soap and shampoo, it can be a good idea to bring your own if you’re particular. If they aren’t available inside, you may see mini sets for sale at the ticket office or a vending machine, so keep an eye out on your way in.
  • Plasters (for tattoos): If you’ve got any smaller tattoos you can cover discretely, skin-colored plasters can be enough. Check our section below for more details.
  • Hair-ties If you’ve got long hair, it should go up as it can be dangling in the water.
  • The changing rooms

    In the locker room or changing room, you’re to take all your gear off before entering the bath area. No underwear, no robes, no towels, just you and all your glory in front of, well, everyone. You can take your modesty towel only with you into the bath area. But it’s okay — everyone else is nekkid too.

    The washing area

    Stools and buckets | Photo by selena hoy

    Once you’re in the washing area, grab a stool and a bucket (if they’re not already at each wash station) and pull up to a tap. Usually, there will be several washing stations available, each with a set of taps, a showerhead and hopefully soaps and shampoos. Sit down and scrub-a-dub. When you think you’re done, scrub some more. If you think it’s embarassing to be this thorough in public, keep in mind that everyone shares the water – the only judgement here is not washing enough. Rinse really thoroughly — no trace of soap should be left. Rinse off your stool and bucket before returning them, of leaving them neatly in front of your station.

    The baths themselves

    Spanking clean in your birthday suit, you can now head to the bath. Dip a toe in to check if you can manage it — doing a hot!hot!hot! dance while hadaka (naked) may not be your best look. Ease yourself in. Your towel should not go in the water — keep it around your neck or folded and placed on top of your head. Long hair should be kept up and should also not be dangling the water.

    No swimming, floating, or splish splashing. Get it together, man!

    Tattoos: The tough one

    Tattoos are a tough one. Many places have rules that prohibit tattoos, so you may have to either cover it up with a bandage if it’s small enough or keep your booty to yourself, alas. There are a few places that allow them, however and things are gradually getting more relaxed.

    Now you know what to do, and how to do it, here are some of the best value for money onsen in Tokyo:

    Saya no Yudokoro

    This pretty onsen has rotemburo, or open-air baths, so you can really be at one with nature. Japanese gardens, fragrant cedar, bathing among rocks and trees — the whole shebang. There are multiple baths and saunas to choose from, including a special hot stone sauna, which does cost extra but the price includes a towel and pajama rental (because you will sweat!). The have body soap and shampoo and conditioner as well as towels to rent.

    Not quite as lovely as Saya, this sento is cheaper and it actually uses real spring water. It has a regular bath, whirlpool bath with massage jets, and an herbal rotemburo. There is a sauna (but this costs ¥600 extra) and the outdoor baths have no roof, allowing you to feel completely out in the open, while still being hidden thanks to their depths.

    Kohmeisen

    A hop, skip and a jump from Nakameguro Station and the cherry-blossom mecca that is the canal, Kohmeisen is an old-school neighborhood sento, complete with murals, with hot and cold indoor baths, an outdoor bath, and a sauna. There’s a coin laundry downstairs, if you want to double up on your wash. This is a fairly small sento, and can get crowded! There are plenty of cafes and restaurants nearby, though, so you could easily wait. (Remember to bring your own soap and towel!)

    Well, what are you waiting for? Gird your loins and get your onsen on.
