戸倉上山田温泉の中で一番歴史のある宿が笹屋ホテルです。その宿の玄関の前に立派な藤木があります。100年の物だそうです。いまはその気の紫花がちょうど咲いています。本当に見事です。近くにいれば、是非、通ってみてください。
Togura Kamiyamada Onsen's inn with the longest history is Sasaya Hotel. In front of their entrance, there is a wisteria tree that is supposedly over 100 years old. Right now, it's purple flowers are in bloom. If you are in the area, I highly suggesting going by and seeing it -- the blossoms are a beautiful sight to see.
