J.Spark Shinjuku

Much smaller than usual hattenba I've visited in Shinjuku, no real spaces that could be used as private rooms as all rooms fit 4-5 people. Pretty basic set up with one main cruising area with some narrow hallways and about 4 larger rooms and one loft area. Only one shower, and you wear underwear in the main cruising area. Most boys are in their 20s and have bangs, that's the "type" for this particular location. Not foreign friendly but not foreign unfriendly either, they just aren't the usual crowd (except some east Asian guys). Someone will probably end up touching on you if you lie in one of the rooms and just wait for a while, but also the "type" here is skinny younger guys so just be aware of that. I'd say come here if you are a skinny guy with bangs or if that's your type.

not foreigner friendly. get ignored because i cant speak japanese

This shop is located a short distance down an alley. Upon entering, you take off your shoes, put them in the bags provided, and then open the door to pay. The price is 1600 yen. There's no security guard, and no six-pack or haircut checks before entry. Foreigners are welcome. To the right is the restroom. Walk past the curtain to find lockers – there aren't many, maybe around 20. The lockers are tall and narrow, making it difficult to store things. USB charging ports are available, but you need to bring your own cable. There's one shower room, and people queue up. Towels and mouthwash are provided. Further inside is a dark area with two levels, mostly a mezzanine. The ground floor is only about 20 steps away. The mezzanine is a bit difficult to access by stairs. It's a good place to sit and watch people go by. Inside the rooms, condoms, lube, and tissues are provided. Some rooms are small, some are large, some are visible from the outside or from the mezzanine, and some are completely closed. This shop is very popular with young people, who tend to be slim and lean.

The problem lies not just with the staff or the store itself, but with the management. There is a risk of personal information being leaked, so please be extremely careful, users and everyone else.

Service at night was fine… staff did not disrespect me at all and I am a foreigner. It took some time for the regular attendees to accept me but eventually it was ok

A safe and great place to go if you are in your 20s, short hair, and thin. They will reject people that aren’t in this demographic for the safety of those who are. I experienced no hostility when I visited as a foreigner

There's a really weird employee there, isn't there? The other day when I went there at lunchtime, I was told, "Please show me a photo ID. Those without one won't be allowed in." I've never experienced anything like that before, so it was unpleasant. And his attitude is absolutely terrible. I don't know if he's choosing based on looks or something, but honestly, it was a very unpleasant experience. If it's that much trouble, he shouldn't be working at a gay cruising spot. Unless this guy is fired, this gay cruising spot has no future.

The staff's customer service was terrible. When I entered at night and later asked for a couple's discount, the staff member just said "Ah" and roughly slammed the money down. If you don't like customer service, don't work at the reception. You're a nuisance to everyone around you.

The staff's attitude during the daytime is quite poor. They are sloppy in their service, and frequently make mistakes with age and price, even when customers show proof of age for age-based discounts. The store itself is also not very clean.
