Mt, Daisetsuzan National Park Stamp Issued on April 20, 1940 (Showa 15) - Specimen -
Daisetsuzan National Park is Japan's largest national park with an area of approximately 230,000 ha, including the Daisetsuzan mountain range centered on Mt. Asahidake (2,291 m), the highest peak in Hokkaido.
Four types of stamps were issued, including a distant view of Mt. Daisetsu and the shore of Lake Shikaribetsu. At the same time, a "small sheet" with a manual was released, but due to the lack of tato (cover cover), a small number of 42,000 sheets were issued.
