Located about a 5-minute walk from Idogaya Station on the Keikyu Line, this is a public bathhouse with natural hot spring water (black water), a common sight in the Yokohama area.
Although it's called "Kusatsu," it doesn't have a highly acidic sulfur spring bath like the famous Kusatsu Onsen in Gunma Prefecture!
However, it boasts a hot indoor black water bath, a lukewarm black water open-air bath, and a cold black water (black water?) bath...
All of these black water baths are natural hot spring water!
There's also a regular hot water bath with a jacuzzi, body massages, and even a reclining bath with a cold water pillow!
In short, it's a very comfortable hot spring bathhouse, and I felt completely relaxed♪✨️🥳

The black hot spring water was fantastic! Natural hot springs are great! There weren't too many people, so it was very relaxing.
After the hot springs, you can enjoy beer, edamame, ramen, takoyaki, and stewed offal for around 400-500 yen. Highly recommended for a weekend getaway!

This bathing facility is located about a 5-6 minute walk from Keikyu Idogaya Station.
Payment is accepted via electronic payment, and the facility is open until 11:00 PM.
While the bathhouse has a slightly historical feel, it is kept clean.
Although there is a dining area, there isn't much space for relaxing, making it feel more like a local public bath than a typical super sento (large-scale public bathhouse).
Many bathing facilities in this area feature black-colored natural hot spring water, and this facility is no exception.
Personally, I found the following points to be distinctive compared to other bathing facilities I've visited:
- The entrance fee is quite cheap at 570 yen (my personal benchmark is around 900-1000 yen).
- Shampoo and body soap are not provided and must be purchased separately.
- There is a sauna, but it requires an additional fee.
- The provided hair dryers are also subject to a charge.
- Tattoos do not appear to be prohibited.
While the entrance fee itself seems inexpensive, if you purchase shampoo and body soap, and use the sauna and hair dryers, the total cost ends up being around 900-1000 yen.
In fact, many other users brought their own shampoo, body soap, and shaving cream.
Regarding the baths, the largest indoor bath was quite hot. Despite being the largest, it was striking that almost no one was soaking in it.
On the other hand, the black water cold bath and the semi-open-air bath were excellent.
Also, when I visited, about 40-50% of the users had tattoos.
Since there aren't many bathing facilities that allow people with tattoos, I think this facility is frequently used by them.
If you are bothered by users with tattoos, you should probably avoid this facility.

Shampoo and body soap are not provided.
Tattoos are allowed.
There are a few parking spaces.
There are four indoor baths, one of which is a cold bath (apparently made with natural hot spring water), and one semi-open-air bath.

As other reviewers have mentioned, there's a regular with tattoos who's there from opening time until late afternoon and is always using his phone in the shower area of the bathroom, and he also leaves his sauna mat there to reserve a spot in the sauna.

This is a hidden gem of a public bathhouse, with a sauna, jet bath, and cold plunge pool, and it's reasonably priced and not too crowded. However, there are a lot of people drawing on the walls, so I think it would be difficult to decide whether to bring small children there.
(Translated by Google)
I didn't get the impression that it was unclean, and the atmosphere among the other users wasn't particularly bad.
However, I never felt like it was a relaxing space. I can't pinpoint the reason—the ventilation, lighting, the color of the bathtub, the overall atmosphere—but I felt a strong sense of discomfort.
When I used the facilities, there was a black bath additive in the cold plunge pool. While it's a matter of personal preference, I didn't know what kind of additive it was, and I found it a little unsettling.
Also, there were areas on the floor where water seemed likely to linger, which may have contributed to my impression.
I also had concerns about the showers. The shower I used had inconsistent water pressure and flow, and I didn't find it comfortable to use.
I got somewhat used to it after staying for a while, but at this price, I would choose a different facility nearby.
On the other hand, the sauna and cold plunge pool temperatures were very good, which was a positive point.
Postscript: I actually enjoyed relaxing in the lobby more than I expected. I'm revising my rating to 4 stars, as I think my initial impression might have been influenced by my preconceived notions about the area.
However, while compatibility with a facility varies from person to person, I personally don't think I'll be visiting again.

I've used the baths a few times. First of all, what bothers me the most is that the regulars chatter incessantly in the sauna. The regulars reserve their spots with sauna mats so they can chat, which is unacceptable for regular customers as they can't sit where they want. As for the water, the showers are too hot, I think they're over 40 degrees Celsius. They're too hot and I wish they'd lower the temperature. It's also obvious that the bathtubs aren't being cleaned, as there's hair floating in them and dirt in various places. Lately, the chatter between the regulars in the sauna has gotten really bad. Sometimes the staff come to inspect and tell them off, but the staff seem to have nothing to do and just chat at the front desk the whole time.

This public bathhouse boasts a surprisingly extensive range of facilities, including a semi-open-air style black hot spring bath, an electric bath, a jet bath, a body massage bath, a sauna with automatic löyly (steam), and a hot spring cold plunge pool.
The changing rooms and lobby are simple but clean, and the availability of light snacks is a big plus. However, there's no space for napping, so don't expect a super sento (large-scale public bathhouse) experience; keep that in mind.

The reasonable prices were very impressive. After a good sweat in the hot springs and sauna, I relaxed my stiff shoulders in a massage chair, and even enjoyed ice cream, coffee milk, and cold ramen after my bath, all for just over 2000 yen. In these times of rising prices, this is truly appreciated, and I will definitely come again!

京急井土ヶ谷駅から徒歩5～6分ほどの場所にある入浴施設。
支払いは電子決済に対応しており、営業時間は23:00まで。
浴場はやや歴史を感じるものの、清潔感は保たれている。
食事処はあるものの、ゆっくり休憩できるようなスペースは特になく、いわゆるスーパー銭湯というよりは、
街の銭湯に近い雰囲気の施設である。
この地域周辺の入浴施設では黒湯の天然温泉をよく見かけるが、ここも黒湯の温泉が特徴。
個人的に、これまで訪れてきた入浴施設と比較して特徴的だと感じた点は
- 入浴料だけであれば570円とかなり安い。（※個人的には入浴料900～1,000円程度を基準としている）
- シャンプーやボディソープは備え付けられておらず別途購入する必要がある。
- サウナはあるものの、別途料金が必要。
- 備え付けのドライヤーも有料である。
- 入れ墨・タトゥーは禁止されていないようである。
入浴料自体は安いと感じるものの、シャンプーやボディソープを購入し、サウナやドライヤーも利用すると、
結局は900～1,000円程度の費用になるのかなという印象である。
実際、ほかの利用者もシャンプー、ボディソープ、シェービングクリームなどを自前で持ち込んでいる人が多かった。
浴場については、内湯の一番広い湯船がかなり熱めである。一番広い湯船であるにもかかわらず、
そこに浸かっている人がほとんどいなかったのが印象的だった。
一方で、黒湯の水風呂と半露天風呂はとても良かった。
また、私が入浴した際には、利用者の4～5割の人が入れ墨が入っていた。
入れ墨を入れている人でも利用できる入浴施設はそれほど多くないため、そうした人にもよく利用されている施設なのだと思う。
入れ墨・タトゥーのある利用者が気になる人は、利用を避けた方がよいだろう。

不潔という印象はありませんでしたし、利用客の雰囲気も特に悪くはありませんでした。
しかし、私には終始あまり落ち着ける空間とは感じられませんでした。換気や照明、浴槽の色合い、館内全体の雰囲気など、何が原因なのかは分かりませんが、居心地の悪さを強く感じました。
私が利用した際は、水風呂に黒い入浴剤が入っていました。好みの問題だとは思いますが、何の入浴剤なのか分からず、私には少し不気味に感じられました。
また、床は水が残りやすそうに見える箇所がところどころあり、それも印象に影響したのかもしれません。
シャワーについても気になりました。私が使用したシャワーは、お湯の出方や水量にばらつきを感じ、私には快適に使えるとは感じられませんでした。
しばらく滞在すると多少は慣れましたが、この価格であれば、私は近隣の別の施設を選びます。
一方で、サウナと水風呂の温度設定は非常に良く、その点は好印象でした。
追記：ロビーで休憩していたら、思っていたよりも気持ちよく過ごせました。
最初は土地柄に対する自分の先入観も影響していたのかもしれないと思い、評価を★4に修正します。
とはいえ、施設との相性は人それぞれだと思いますが、私個人としては再訪はしないと思います。
