Nagoya Aichi Japan

Tokugawa Ieyasu had in 1610 ordered the various daimyo to help with the building of a new castle on the site of one built by Imagawa Ujichika around 1525.

Oda Nobuhide had taken it from Imagawa Ujitoyo in 1532, but later abandoned it.

This new castle, meant to secure an important position on the Tokaido highway and to ward off attacks from the direction of Osaka, is to be the new capital of the existing Owari Province and many of the materials used are sourced from the smaller Kiyosu Castle, including Kiyosu castle's tenshu, located in the existing provincial capital of Kiyosu.

Nagoya castle's construction is completed in 1612.

The 1854 Tōkai earthquake on December 23, 1854, which strikes primarily in the Tōkai region but destroys houses as far away as in Edo, closely follows the Great Nankaidō earthquakes and tsunamis.

The accompanying tsunami causes damage along the entire coast from the Bōsō Peninsula in modern-day Chiba Prefecture to Tosa Province (modern-day Kōchi Prefecture).
