Considering the Green Tenryokaku in Takayama?

Higashiyama Walking Course by Pixiekatten
The hiking trail starts in Teramachi temple district. Around here there's dozens of temples and shrines. It is then taking you past rural suburbs and through the hills of Shiroyama Park where you'll find the ruins of Takayama's castle. The trail is about 3,5km and you don't need a map, there's signs all the way leading you right.
The walking course was a nice way to spend a few hours after the crowds in Sannomachi area. The view from Shiroyama Park is nice but not breathtaking. However it was from up there I discovered the golden roof of The Mahikari Main World Shrine and I had to extend the walk across whole of Takayama to get a closer look. (See seperate tip.)
