Map of Onsen's in Japan!

One of my favorite experiences in Japan was going to as many onsens (hot spring baths) as possible.  They were so relaxing and the food was usually great.  Many of them are in beautiful locations.

Soul of Japan has made a map of his favorite onsens.  

While I have not visited all of them I really want to do so!

Let me know if you have been to any of them and how you liked them!
