Japan Astronomical Heritage (日本天文遺産, Nihon tenmon isan) is an initiative aimed at the recognition and valorization of the astronomical heritage of Japan. Analogous to the International Astronomical Union's list of Outstanding Astronomical Heritage, the first assets were designated by the Astronomical Society of Japan in March 2019 (FY2018); as of March 2026 (FY2025), twenty entries are on the list. Three categories are recognized: sites (historic sites and buildings, such as observatories), materials (historically significant items, such as astronomical instruments), and documents (including historic astronomy-related literature).
