Reservation for Tsurunoyu Onsen

How can we reserve to stay in Tsurunoyu Onsen. In their website for reservation they use Japaness language for explanation. DO we have to call directly to them? Or is there any easier way to book?

Haven't stayed there but googled it. There is an English section of their website that has a phone number for booking. If you'd prefer to do it online, https://www.japaneseguesthouses.com/ryokan-single/?ryokan=Tsurunoyu+On...

Funny that JGH still lists the adress as Tazawako-machi, Senboku-gun. Senboku-gun became Senboku-shi in 2005.

You can just use http://www.japaneseguesthouses.com/

That's what I did, and it seems to work fine. You merely ask them to inform at the Ryokan if they have rooms available. Then you receive an e-mail from Japanese Guest Houses about the costs and you can send a confirmation if you want them to book it for you.

Might be easier than trying to figure it all out in Japanese.
