State Council Moves to Classify Osaka Castle Tower

Japan's Cultural Affairs Council recommended Friday that Osaka Castle's main keep become an Important Cultural Property, sending the proposal to culture minister Yoshihiro Seki. The tower stands on a site marked by repeated destruction and rebuilding. Now a state cultural body is deciding how to classify it officially.

Officials haven't announced the designation. If approved, it would add to a national register of 2,619 buildings designated Important Cultural Properties, including 235 National Treasures. The council proposed eight buildings in total, and officials expect the final announcement in the near future.

Who Classifies the Past

Osaka Castle's current main keep was completed in 1931 using donations from local residents. The structure is a steel-reinforced-concrete museum with five external tiers and eight floors, built to recreate the castle's appearance during the time of warlord Toyotomi Hideyoshi. Designers drew on historical research into the original castle.

The recommendation brings a local landmark into a national system of official cultural status. Residents helped fund the present tower, while the Cultural Affairs Council sent its decision to a culture minister; the public announcement is still pending. The source describes a recommendation and expected approval, not a completed designation.

Inside, the museum displays items associated with Hideyoshi and other historical exhibits. Its eighth-floor observation deck offers panoramic views of Osaka. The building's design as a local history museum with an observation deck later influenced castle-tower reconstructions across Japan.

A Site Rebuilt Again and Again

The original main keep, built during Hideyoshi's time, burned down in 1615 during the Summer Siege of Osaka. The Tokugawa shogunate rebuilt a second tower, but lightning destroyed it in 1665. The present tower is the third on the site.

Those changes form part of the history the museum presents and the council considers in its recommendation. The current keep isn't the original structure. It's a twentieth-century reconstruction, designed around historical research and built with donations from local residents. Its official classification concerns this present building and its place in the site's history.

The council also recommended four structures at Zuisenji temple in Nanto, Toyama Prefecture; the Hatto, or Dharma Hall, at Kenninji temple in Kyoto; and the main building of the Nara Hotel in Nara. Along with Osaka Castle's main keep, these make up the eight buildings proposed for Important Cultural Property status.

Another District on the Register

Separately, the council recommended that officials designate the Yoshihara district in Maizuru, Kyoto Prefecture, an Important Preservation District for Groups of Traditional Buildings. The former fishing town contains traditional townhouses dating from the final years of the Edo Period (1603-1867) through the mid-Showa Era.

If approved, Yoshihara would become the nation's 131st such district. As with the castle proposal, the council has made a recommendation, not announced a completed designation. The process gives official bodies the power to assign cultural status to buildings and districts; local residents' contribution to Osaka Castle's reconstruction remains part of the history those institutions are weighing.
