Yanagiya is a nice little local onsen. They do not have too many rooms so you will not feel overcrowded. It is a nice place to spend for days to relax your body and mind.
Staff are very friendly and helpful. They can speak limited English but in case you come across any issue with language, feel free to use translation app.
If you are driving, the onsen is easy to find and there is a carpark in front of the Onsen with plenty of space. There are also 2 x EV charging but not sure if they are for onsen guess.
The room is spacious, clean and tidy. The air conditioner is featured with heater and cooler function, so you don't have to worry about weather during winter and summer.
The hot spring is open for 24 hrs, except time when they swap between male and female access, usually it takes 30 minutes and they take this opportunity to clean up the facilities too.
Food are generally fine and portion is reasonable. Staff are caring d considerate. We have two kids at age of 7 and 9 and they do not take spicy or raw food. When they noticed, they have offered to tailor made the breakfast for the kids so that they don't prepare food that kids do not eat.
Staff Ryo san is very friendly and helpful. He is very informative and I enjoy chatting with him. Our room comes with a toilet as shown. An option for a private bath is available costing 500 yen for 30min. I approached Ryo san and book my timing (first come first serve) only after I checked in. My one night stay comes with a simple breakfast the next morning. The homely meal is rice with egg omelette and some other dishes. Roughly a 15min walk to Kofu train station.
