Japan Astronomical Heritage

The Astronomical Society of Japan designates sites, materials, and documents of historical significance in Japan from the perspective of astronomy as the Japan Astronomical Heritage. The first of the three categories is historic sites and buildings, including observational facilities. The second is historically significant materials, including an object involved in an important astronomical discovery. Observational instruments and measuring instruments are also in this category. The last category is literature, such as astronomy-related documents of historical significance.
