Important Cultural Property

What an Important Cultural Property is

An Important Cultural Property is tangible cultural property that the Minister of Education, Culture, Sports, Science and Technology has designated as important under Article 27, paragraph 1 of the Act on Protection of Cultural Properties.

Tangible cultural property here means buildings, paintings, sculpture, craft works, calligraphy, books and historical documents of high historical or artistic value, together with archaeological materials and historical materials of academic value. Article 2 extends the definition to land and other objects that form a single unit of value with the item itself, which is why a farmhouse and its plot are sometimes designated together.

Administration splits into architecture and fine arts. As of 1 August 2026 the total stood at 13,558 designations, comprising 2,605 architectural designations covering 5,597 structures and 10,953 designations of fine arts and crafts. That total includes every National Treasure. Architecture carries two figures because a temple or castle precinct is often designated as one case covering many separate structures.

Designation brings obligations. Altering the present state, or acting in a way that affects preservation, requires permission from the Commissioner for Cultural Affairs. Export is prohibited except by special permission. Repairs fall to the owner, with national subsidy available where costs are beyond reach, and changes of ownership or location, along with any loss or damage, must be reported.

Telling the national tier from local ones

Prefectures and municipalities also designate cultural property under their own ordinances, and several prefectures use wording close to the national term. A sign reading Important Cultural Property is therefore not proof of national designation. The National Cultural Properties Database run by the Agency for Cultural Affairs settles the question: if the item appears there, the designation is national.

Record entries list the designation date, the designation number, the Insū or recorded quantity, and the structure and form. Items raised to National Treasure status carry two dates, because promotion normally follows an earlier designation as an Important Cultural Property rather than replacing it.

Designation does not always stop at the object itself. Ridge tablets, drawings and other closely associated items may be designated alongside it as Tsuketari, and these count as part of the same designation.
