1000 Yen - Reiwa Nikkō National Park

Part of Japan's ongoing prefectural coin program, which has been issuing commemorative silver pieces tied to national parks and regional landmarks since 2016. Nikkō National Park, established in 1934, straddles Tochigi and Fukushima prefectures and encompasses the Tōshōgū shrine complex — the mausoleum of Tokugawa Ieyasu, whose remains were interred there in 1617. The park designation itself was partly a bureaucratic move to protect the shrine environs from commercial encroachment during Japan's rapid industrialization.

The Reiwa era designation places this firmly in the post-Heisei administrative reissue cycle.
