Super Japanese experience: traditional bath house with great pools in&outdoor and izakaya with tasty food. Just make sure to cover your tatoos if you have any, they're very strict and won't let you in
Clean facilities, friendly staff, nice outdoors areas w/ one sauna and a steam room. Nice variety and decent price. Easily accessible (10 minute walk) from the Mita-sen line. Great for wintertime.
Onsen in a suburban quiet Tokyo area. It's more original and cheap. You get a towel for some extra bucks. Has a restaurant, a zen garden, sauna, jacuzzi and a relaxing spring in the open.
Good place to experience an onsen. Make sure to go in the mornings on weekdays to avoid crowds. It’s on the Toei Mita Line - Shimura-Sakaue station and is walking distance from the station.
Plan for a few hours - 2 hours to enjoy all the hot springs and steam rooms then a relaxing meal. Good prices and good food. Mainly locals which is nice.
