Yamadera

 I thought this was very interesting. The part of the structure on the left is old and made from wood but on the right it is new and has aluminum sashes.

 This little altar is out on a rock hanging over the valley.

 It was closed and the stairs were roped off so I could not see inside.

 If you look carefully in the middle of the picture, you can see the roof of a mediation hall. Apparently it is not open to the public and the path to it is closed.

 The upper building is the main temple. The building with the red roof is some sort of administrative building or a meeting place or a meditation hall.

The red altar building is directly behind this building, which was also closed.
