About this site

Facts such as eras, structures and locations are edited and translated by us from the Agency for Cultural Affairs’ database of nationally designated cultural properties. The Agency and the national government did not produce or supervise this site. We do not copy the database’s commentary; the text on our pages is our own.

Find National Treasure buildings and Important Preservation Districts by type or area. Each page ends with nearby places and places of the same type or prefecture, so you can combine what stands in one town into a half-day visit.

For places with a full write-up, we list access, opening hours, closing days, fees and the best times to visit, checked against official information from the temple, shrine, castle or local government, with the date we checked. Fees and hours can change, so please also check the official site before you go. Pages without a write-up do not have this information yet.

Pages we have not written yet are marked “Text in preparation”. They carry no ads and are kept out of search.

If you own or manage a property and would like a correction or removal, please write to support@jtrip-portal.com. We will check and respond promptly.

The site runs on ads and on affiliate links to travel and activity booking sites. Ads are labelled “Advertisement” and affiliate links “PR”. Neither affects which places we list or the order they appear in. Ad delivery uses cookies from third-party vendors, including Google, and may show ads based on your past visits. You can turn off personalized ads in Google Ads Settings (adssettings.google.com).

We use only reusable photos published on Wikimedia Commons (CC0, public domain, CC BY, CC BY-SA). If we are not sure a photo shows the building, we do not use it; a page without a photo shows a plain colour and the type’s name. We do not use generated images. Each photo’s author and licence appear beside it.

To improve the site we use Google Analytics. With cookies it collects the pages you view, your device and browser, and whether you clicked a link to a booking site, in a form that does not identify you. The data is handled under Google’s privacy policy. You can stop the collection by disabling cookies in your browser or with Google’s opt-out add-on.
