Which tattoo friendly onsen in Tokyo accept reservations?

Yes — in Tokyo the best way for tattooed visitors to use onsen is to reserve private (kashikiri / family) baths or book facilities that explicitly allow tattoos when you make a reservation. Major Tokyo spa complexes and day‑use onsen such as Oedo Onsen Monogatari (Odaiba) operate reservable private baths, and large urban spas like Thermae‑Yu (Shinjuku) and Spa LaQua (Tokyo Dome City) offer reservation or private‑use options — always confirm tattoo policy on booking [1][2][3][4].

Overview: tattoos and bathing culture in Tokyo

Japan’s public onsen and sento historically restrict visible tattoos because of associations with organized crime; national guidance from the Japan National Tourism Organization (JNTO) recommends using private/reservable baths or confirming policies with each facility ahead of visiting [1]. The Tokyo Metropolitan tourist guidance also urges tattooed visitors to contact facilities in advance and suggests private kashikiri baths as the safest option [2].

Tokyo‑specific rules and official guidance

JNTO’s page on tattoos and onsen explains that policies vary by facility and that private family baths (kashikiri) are the reliable option for tattooed guests; it recommends contacting the facility in advance if you plan to enter a public bath [1]. Go Tokyo’s official advice repeats this for visitors in Tokyo and lists ways to find tattoo‑friendly options or reserve private time slots or rooms where available [2].

Reservation options that work for tattooed guests

There are three practical reservation pathways for tattooed visitors in Tokyo:

• Reserve a kashikiri (private / family) bath — these are enclosed rooms with a private tub or small hot‑spring pool you book by time slot.
• Book a private relaxation room or private spa package at large commercial onsen/spa complexes (day‑use spas often have private rooms or reserved booths).
• Choose facilities that explicitly state tattoos are allowed for booked private use; always get confirmation in writing (email) or on a reservation page.

Both JNTO and Go Tokyo recommend contacting facilities directly to confirm availability and tattoo policy before you travel [1][2].

Tokyo facilities with reservable private baths (examples)

Below are Tokyo facilities that advertise reservation or private‑use options; check each venue’s official reservation page or call to confirm tattoo acceptance and detailed conditions.

1. Oedo Onsen Monogatari (Odaiba) — a large onsen theme complex that operates private/family bath options and private relaxation rooms; their official English site includes information on private facilities and bookings, so you can reserve a kashikiri style room for tattooed guests [3].
2. Thermae‑Yu (Shinjuku) — a major urban spa near Shinjuku Station with day‑use packages and private/paid relaxation areas; their English information page describes services and reservation contact points — call or email to confirm tattoo policy for private bookings [4].
3. Spa LaQua (Tokyo Dome City) — a large Tokyo spa complex often listed in Tokyo tourism guidance as a commercial spa with private or reservable options; Go Tokyo’s tourism advice recommends checking large commercial spas’ private packages and contacting them directly about tattoos [2].

How to reserve and what to tell reception

When you contact a facility to reserve, follow these concrete steps to avoid confusion at check‑in:

1. Call the facility or use its official reservation form. Use the English contact on the venue’s site where available (e.g., Oedo Onsen Monogatari’s English reservation links) [3][4].
2. Say: “I have tattoos and would like to reserve a kashikiri / family bath (or private room). Is that possible?” In Japanese you can say: “irezumi ga arimasu. kazokuburo / kashikiri wo yoyaku dekimasu ka?” (依存はありません? — use simple English at major venues if needed.)
3. Confirm three specifics: acceptance of visible tattoos for the private booking, the fee for the private time slot, and the maximum time and number of people included in the reservation.
4. Ask whether towels, soaps, and changing rooms are included and whether any ID or paperwork is needed at check‑in.
5. Request written confirmation (email or booking page) stating the reservation includes private use and that tattoos are acceptable for that booking; keep it on your phone for check‑in.

Practical tips and etiquette

Follow these practical tips when planning to use a private onsen in Tokyo:

• Book early. Private baths and reserved time slots at popular spots (Odaiba, Shinjuku, Tokyo Dome City) can fill on weekends and holidays — aim to reserve at least several days ahead for weekday travel and 1–2 weeks for busy weekends.
• Don’t assume public spaces allow tattoos. Even facilities that permit tattoos for private rooms may still ban visible tattoos from communal baths — rely on your reservation confirmation [1][2].
• If you cannot reserve a private bath, ask whether the facility provides waterproof tattoo cover stickers or has designated tattoo‑friendly time slots; some places offer alternatives but availability varies by venue [1][2].
• Respect Japanese bathing etiquette in the private room: wash before entering, keep the area tidy, and follow staff instructions regarding water temperature and time limits.

Conclusion

In Tokyo the reliable solution for tattooed visitors is to reserve a private (kashikiri/family) bath or a private room at a commercial spa and to confirm tattoo policy when you book. Use official venue pages and Tokyo tourism guidance to identify options (Oedo Onsen Monogatari in Odaiba, Thermae‑Yu in Shinjuku, Spa LaQua at Tokyo Dome City), request written confirmation, and verify fees and time limits before you go [1][2][3][4].
