Sign board of Annex building is not clear. Luckily the male staff came out from main building, guiding me (car) to Annex building. He is very friendly and enthusiastic to introduce onsen inside hotel. This is a very old hotel over 200 years. Room furniture is very old. Light is dark. I was a bit scare in the room and switched on the lights to sleep. Another scarring matter was the insect inside blanket. I killed it by shoes. Although it is old and got insect, I was still happy to stay in the hotel due to the friendly people. Onsen is good. After onsen, I can sleep well. Go to the roof top, there is a surprise scenic view of Ryoko Kogen which is amazing and unforgettable.
