After hiking over Tamagatao, a mountain pass between Temple 12 and Temple 13, pilgrims will come across this enclosed hut and rest area. It has a door, windows, and some benches with an awning overhead. There is also a roadside shrine (jizo) across from it with enough space to park bicycles or motorcycles. It is a great place for many pilgrims to rest because the trails from Temple 12 onwards can be quite steeply downhill and hard on the knees.
Sidenote: The mountain pass, written in Japanese as 玉ヶ峠, is pronounced “Tamagatao” instead of “Tamagatouge” as the kanji is pronounced and according to to dictionaries.
