List of Cultural Properties of Japan – historical materials (Okayama)

This is a list of designated Important Cultural Properties of Japan that are categorized as historical materials and located in Okayama Prefecture. This designation is made by the Japanese government under the Law for the Protection of Cultural Properties. Historical materials (歴史資料, rekishi shiryō) encompass documents, artifacts, and other materials that are considered to have significant historical value for understanding Japan's past. This list specifically includes those items physically located within Okayama Prefecture.

The designation of an item as an Important Cultural Property indicates that it has met specific criteria for historical, artistic, and scientific value. The listed items represent a range of historical periods and may include documents such as diaries, letters, official records, maps, and other written materials. They may also include archaeological finds, tools, clothing, furniture, and other objects that provide insight into the lives and customs of people in Okayama Prefecture throughout history.

The Law for the Protection of Cultural Properties aims to preserve and utilize these materials for future generations, ensuring that the historical heritage of Japan, and in this case, specifically Okayama, is maintained and accessible. This list typically provides the name of the cultural property, its location (typically a museum, temple, shrine, or private collection within Okayama Prefecture), and a brief description of its significance. Further details about each item can often be found through the Agency for Cultural Affairs of Japan or local prefectural authorities. The complete official list is maintained and updated by the Japanese government.
