1000 Yen - Reiwa Daisetsuzan National Park

Daisetsuzan, covering roughly 2,267 square kilometers in central Hokkaido, became Japan's largest national park in 1934 under the National Parks Law enacted just two years prior — the country's first systematic attempt to codify landscape preservation. The park's Ainu name, "Kamui Mintara," translates loosely as "playground of the gods," a designation that long predates Japanese administrative boundaries.

This piece belongs to Japan Mint's ongoing prefectural commemorative silver program, which rotates through Japan's 47 prefectures. Hokkaido's sheer geographic scale — roughly 22% of Japan's total land area — has given it recurring prominence across the series.
