Tokyo Onsen & Sento Guide — Prices, Etiquette & Tattoo Policies

Picking Your First Bathhouse

“Going to a bath” in Tokyo can mean very different things depending on whether you walk into a neighborhood sento, a city-style spa complex, or a day-trip onsen with a garden. Here’s a side-by-side comparison using four beginner-friendly examples: Daikokuyu and Kosugiyu for neighborhood sento, RAKU SPA 1010 Kanda for the urban spa category, and Maenohara Onsen Sayanoyudokoro for a day-trip onsen.

If you want the cheapest way to experience Tokyo’s bathing culture, a neighborhood sento is the obvious choice. If you’d rather spend half a day relaxing, a place like RAKU SPA works better. And if you care most about the onsen experience itself, a day-trip onsen like Sayanoyudokoro is more satisfying.

The experience starts at the entrance. At traditional sento with a bandai (front desk), the men’s and women’s sides may split right from the door.

How Bathing Works

The parts that trip people up the first time: where to take off your shoes, when to wash, and what counts as a faux pas. This order covers it.

1. Take off your shoes at the entrance and put them in a shoe locker. At bandai-style sento, the entrance may split into men’s and women’s sides right away — the Tokyo Sento Association guide recommends checking the noren curtain or door signs.
2. Pay at the counter. Tokyo sento charge a flat rate: ¥600 for ages 12 and over, ¥200 for children 6–11, ¥100 for children under 6. Two phrases are enough: 「大人一人です」 (otona hitori desu / “One adult”) and 「タオルはありますか」 (taoru wa arimasu ka / “Do you have towels?”).
3. In the changing room, undress completely. Both the Tokyo Sento Association and JNTO confirm that swimsuits are not worn.
4. In the bathing area, pour water over yourself (kakeyu) first, then wash at a washing station. JNTO lists washing thoroughly with soap and shampoo before entering the tub as the basic rule.
5. When you get in the tub, keep your towel and long hair out of the water and don’t bring your phone into the bathing area. Tokyo sento tend to run hot, so keep your first soak short.
6. Before heading back to the changing room, dry off. The Tokyo Sento Association guide asks you not to return to the changing room dripping wet. Grab some water and you’re done.

Wash first, soak second. People notice this one basic step more than any elaborate routine.

Tattoos and What to Bring

There’s no single tattoo rule for Tokyo bathhouses. JNTO also recommends checking with each venue in advance. A quick look at three official websites shows just how much the policies differ:

Even among these three, you can’t generalize by type — it’s not “sento = OK” or “onsen = no.” If you have a large tattoo or want to avoid being turned away at the door, check the official FAQ beforehand or ask at the counter: 「タトゥーは大丈夫ですか」 (tattoo wa daijoubu desu ka / “Are tattoos OK?”).

You can get by with very little at a neighborhood sento. The Tokyo Sento Association guide says bringing your own towel and soap is standard, but most places sell them on-site. For specifics: Daikokuyu offers a towel rental set for ¥130, RAKU SPA 1010 Kanda’s 10-hour plan includes face towel, bath towel, and loungewear, and Sayanoyudokoro rents bath and face towels for ¥380.

Payment options also vary. Daikokuyu is cash only, while Sayanoyudokoro accepts credit cards, transit IC cards, and some QR payments. A safe assumption while traveling: neighborhood sento usually mean cash, day-trip onsen are more likely to take cards.

Four Beginner-Friendly Picks

These four venues publish pricing and rules on their official websites. Check the plan, visit date and entry conditions before going; optional extras and special-day charges can change the total.

Daikokuyu

Daikokuyu is a short walk from Oshiage Station, and its deal is straightforward: ¥600, tattoos allowed. A towel rental set costs ¥130, and shampoo and body soap are provided free. If you just want to try a sento once while in Tokyo, this is one of the easiest places to start.

Kosugiyu

Kosugiyu has been running since 1933, with the standard ¥600 admission. It’s a good pick if you want to soak up the Koenji neighborhood vibe along with the bath. Tattoo and payment policies aren’t prominently listed on the website, so check directly before visiting.

RAKU SPA 1010 Kanda

RAKU SPA 1010 Kanda offers a sento plan at ¥600 and a 10-hour plan at ¥2,090 weekdays / ¥2,390 weekends and holidays. The 10-hour plan includes towels and loungewear, with access to lounge areas and sauna. The tradeoff: tattoos are not allowed. Good for days when you want more than just a bath. Staying past 01:00 adds a late-night surcharge, and exceeding the 10-hour allowance adds ¥200 per 30 minutes.

Maenohara Onsen Sayanoyudokoro

Maenohara Onsen Sayanoyudokoro costs ¥970 on weekdays and ¥1,300 on weekends and holidays. From November 4, 2026, weekday entry at or after 18:00 costs ¥1,000; the entry-gate passage time determines the rate, so weekday entry by 17:59 remains ¥970. Busy-day rates or extra charges for longer stays may apply. It suits visitors looking for garden views and a longer stay. Tattoos must be fully covered by up to two designated stickers. Credit cards, transit IC cards and some QR payments are accepted.

Beyond neighborhood sento, Tokyo has day-trip onsen where you can stay longer and enjoy the setting. Choose based on what matters most to you.

Spa & Day-Trip Onsen Tickets on Klook

If you’d rather book an English-language e-ticket from your phone, a few Tokyo and Hakone hot spring facilities list tickets on Klook. Check each ticket’s mobile-voucher instructions, contact requirements, included areas and entry conditions before buying.

Spa LaQua (Tokyo Dome City) — A 1,700-meter-deep natural hot spring spa attached to Tokyo Dome City, with open-air baths, carbonated baths, and several types of saunas. Convenient if you’re already visiting Tokyo Dome or LaQua.

Thermae-Yu (Shinjuku) — A hot spring complex in Kabukicho, about 9 minutes from JR Shinjuku Station’s East Exit or 2 minutes from Shinjuku-sanchome Station’s E1 Exit. Open 24 hours. Compare the Klook ticket’s included services and date restrictions with the venue’s current admission price before booking.

Hakone Yuryo (day trip from Tokyo) — A peaceful day-trip onsen in Hakone with private and outdoor baths, about 90 minutes from Shinjuku. Free shuttle from Hakone-Yumoto Station. Worth combining with a Hakone Freepass for the round trip.

Hakone Kowakien Yunessun (day trip from Tokyo) — A hot spring theme park with wine, green tea and coffee baths, plus outdoor pools. The Yunessun area uses swimsuits and can suit families or visitors uncomfortable with communal nudity. Tattoos must be hidden, for example with a rash guard; the separate Mori no Yu bathing area requires complete coverage with up to two designated paid stickers. If that is not possible, the venue directs guests to its reservation-only private baths. Check which area your ticket covers.

For a neighborhood sento such as Daikokuyu or Kosugiyu, check the venue’s own admission and payment instructions. Daikokuyu explicitly accepts cash only; confirm Kosugiyu’s current payment options directly.

When Things Go Wrong

Turned away for a tattoo: Don’t push it — switch to a venue that confirms it accepts your tattoo. JNTO suggests considering private baths (kashikiri buro), but a private bath or a ryokan room with its own bath does not by itself guarantee tattoo admission. Ask the venue about its policy before booking, especially for a large tattoo.

Forgot your towel or soap: Most Tokyo sento sell them at the counter. No need to rush back to your hotel — just ask 「タオルはありますか」 (taoru wa arimasu ka / “Do you have towels?”) and you’ll be fine.

Water is too hot: Pour kakeyu over yourself first to warm up gradually, and keep your first soak short. The Tokyo Sento Association guide warns against turning on cold water without asking — it can cause trouble with other bathers. If it’s unbearable, move to a different tub or get out.

Uncomfortable being naked around others: JNTO lists private baths and rooms with in-room open-air baths as alternatives. You don’t have to start with a public bath if it doesn’t feel right.
