Maeda Toshinaga, the son of Maeda Toshiie and second
daimyō of Kaga Domain retired in 1605 at the age of 43, and moved from
Kanazawa Castle to
Toyama Castle. The reason for his early retirement is uncertain, but one reason could have been that he wanted to ensure the succession of the Maeda clan by turning the position of
daimyō to his younger brother
Maeda Toshitsune, who was married to the daughter of
shōgun Tokugawa Hidetada. Toyama Castle burned down in 1609, and Toshinaga relocated to Uozu Castle while waiting for permission from the shogunate to build a new castle at a place named Sekino. The design of the castle was done by
Takayama Ukon, who had been exiled to
Kaga Province by
Toyotomi Hideyoshi. When the castle was completed, the location was renamed "Takaoka". Later the Maeda clan rebuilt Toyama Castle as the administrative center of Etchū Province, but kept the site of Takaoka Castle as a location for warehouses to store tax rice for Kaga Domain. Within the castle grounds were also a
sake brewery, salt warehouses, a gunpowder factory, and the offices of the local governor, the Takaoka
Machi-bugyō. Many of these buildings were destroyed in a fire in 1821. After the
Meiji restoration, the government district office for
Imizu District, Toyama was built in the castle site. == Current situation ==
