What is 24 Kaikan Shinjuku?
As we’ve mentioned, 24 Kaikan Shinjuku is what might be considered a “typical” bathhouse for gay cruising. Japan has a long and proud history of public bathing, which is today segregated by gender. This history is quite disconnected with the cruising culture that has emerged in public baths overseas, and so anyone looking to go to an onsen or sento to hook up will almost certainly leave disappointed — and possibly in trouble.
24 Kaikan Shinjuku is one bathhouse in a small Tokyo chain that caters exclusively to gay men for the purposes of hooking up. While there are other 24 Kaikan venues in Ueno and Asakusa, the Shinjuku branch is arguably the most famous.
Men aged 20 and above are permitted entry: if you’re lucky enough to look young, you will have to present ID to confirm your age. The age range of the clientele is quite broad, as are the body-types of the people who go. Some hattenba in Tokyo can be very strict with the age and appearance of people they’ll allow to let in, but 24 Kaikan Shinjuku is very welcoming to all ages and body types.
How to Get There and Entry Procedure
As it is located in Shinjuku Nichome, the nearest train station is Shinjuku Sanchome, served by the Fukutoshin Line, the Marunouchi Line, and the Toei Shinjuku Line. Taking exit C8, walk forwards towards the main road, then turn left without crossing. When you come to a ramen restaurant on your left, turn left, and continue walking forward for approximately three minutes. You will find 24 Kaikan Shinjuku on your left, just in front of a public park. The sign at the front of the building is in Japanese, and reads: 24H会館.
Once you enter, English instructions are provided, making it easy for English speakers. However, here’s a quick run-down for you.
- On entry, head to the reception area on the second floor. Remove your shoes, put them in a footlocker, and take the key. You will also buy your entry ticket from a vending machine. The prices will vary depending on your desired duration and your arrival time. If you want to book a room, you will need to do so here.
- Give the key and ticket(s) to the receptionist to receive your locker key and towel set. You can also take this opportunity to request free condoms, as well as purchase lube
- Go to your locker and remove your clothes. Next, head upstairs to the real bathing areas.
- Wash yourself thoroughly. Even though this is not a traditional onsen, it is still protocol to clean yourself before getting into any baths: they are for relaxing (and “relaxing”), not for washing.
All in all, you don’t need to prepare much. As mentioned, towel sets are included in the entrance price, but depending on your plans, you might want to bring extra towels. Remember, this is a gay sauna where special interests and unique preferences are the norm, so it’s not just about chilling out in a bath. It’s an immersive experience in an intimate environment.
Practical Concerns
Before you go, there are a number of concerns that you might have. Who is allowed? How should you act? Let’s address some of these worries.
First of all, as we’ve said, all men 20 and above are welcome. This includes foreigners, and having tattoos is no barrier to entry. You do not have to speak Japanese to enter, but it is recommended. Couples are also allowed. I have also seen trans men in 24 Kaikan Shinjuku.
Food is available on the second floor. This food costs extra, and don’t expect fine cuisine. Be aware that fresh-cooked food is not always available, and so you may have to make do with food from vending machines.
An Eight-Floor Playground?
One of the most impressive aspects of 24 Kaikan is that it is an astonishing eight floors of gay bathing fun… kind of. The first two floors don’t actually have baths at all: the first floor is a parking lot, for those arriving by car. Rates are ¥330 per 15 minutes between 9am and 6pm, and ¥330 per 20 minutes between 6pm and 9am. Between 9am and 6pm the maximum charge is ¥3,600; between 6pm and 9am the maximum charge is ¥1,500. The second floor is the reception area, where you can change and store your things. This still leaves an impressive total of six floors for bathing and fun.
So what are on those floors?
Starting with the third floor, you’ll find the big bath and sauna. It’s a large facility that looks and functions like a classic onsen. This is where everyone starts their experience. The showers next to the bath are a popular spot to meet people, so don’t be surprised if someone approaches you for some fun. You’ll also find a tanning room, which (as you might expect) has tanning beds, so you can work on your tan while you put in work.
On the fourth floor, you’ll find a large shared room and a video room. The shared room has a lot of beds, all in a common area, for guys to lie back as you meet and greet. The video room is a place to take in explicit movies that you can enjoy with your neighboring cinephiles.
The fifth, sixth, and seventh floors all have shared rooms, but are mainly for private rooms. These must be reserved at the reception before entry.
Finally, if you’re looking to cool off, head to the eighth floor: the rooftop. Here, you can take in the outside air, or jump into a mizuburo cold-water bath. Please note, however, that this floor has been known to be open infrequently.

A Personal Perspective
Now that you’ve unwound on the third floor, let’s talk more about the fourth floor. This floor is where the real action happens. The large room here is where people gather to have fun, either in groups or pairs. The atmosphere when I went was highly erotic, and the atmosphere of active engagement and physical interaction fills the air. You’ll see everything from passionate embraces to group activities. It’s great for anyone into watching or being watched.
I saw all sorts of people here, mostly Asians in their 20s to 50s, and all body types. 24 Kaikan is known as a place where many foreigners — and Japanese men who like them — frequent. I went on a Monday night, and it was packed. Guys may approach you for all kinds of sexual acts, but respect is paramount. You can accept or decline, and if you decline, they’ll just move on to someone else. Be prepared for some rejection too: it’s part of the experience.
The shower booths on the third floor also have glory holes, as well as swings and other furniture for slightly spicier play, if that takes your interest.
Etiquette, Consent and Privacy
Let’s talk a little about how to act at 24 Kaikan Shinjuku. Respect and consent are very important. While this is a great place to hook up, it is not guaranteed, and someone looking at you is not the same as them agreeing to sex. If someone refuses your advances, you should respect that immediately and move on.
There is, for obvious reasons, no photography allowed inside the building.
