Old postcards related to Mount Chokai, a sacred mountain in Yamagata Prefecture. All are monochrome (single color). There are 10 postcards featuring alpine plants such as Hinazakura (Primula cuneifolia), Chiguruma (Mountain Avens), and Mougengoke (Sundew), 12 postcards with mountain climbing photos, including the iron ladder at Gyojadake and views from the summit of Mount Chokai, and 4 postcards of scenery, such as the Okunihitotsu Shrine. 22 are unused. Only 4 have writing on them. As in the last photo, all are written horizontally from right to left. 　山海鳥 (Chokai Mountain and Sea) 　11.8.13 (August 13, Showa 11) 　念記拝参 (Commemorative Visit) The stamp indicates the date was written from right to left, so it is from Showa 13 (1938). This was a time when the war in China was expanding and Japan was heading towards the Pacific War. For sale to those with an interest. #ShowaRetro #Postcards #MountChokai #MountainPhotography #AlpinePlants
