This report is a database of the history of mountain huts throughout Japan in the prewar period. The source is “Yama Nikki” published by the Japan Alpine Club. This report aims to compile a list of mountain hut names, construction/renovation years, elevation, and other information to serve as a basic resource for research on the history of mountain architecture. As a result, we were able to create a database that can be referenced by region and by year, and to clarify the historical value of the “Yama Nikki” and draw out its potential.
