Cold day so really enjoyed the time we spent at this onsen today, cost 12000yen for 4 adults which included some beers sake and alot of food after getting out of the onsen...is very roomy and comfortable we spent maybe 4 hours there, they also have a room where you can sit in some lazyboy chairs and relax , will go again, believe it gets busy on the weekends, we went on a monday around 11am and was not very busy

We keep coming back to Yura no Sato because it is clean, has ganbanyoku, massages and way cheaper than other places in Tokyo. They also sell vegetables and fruit.
