At the center of this public park is — as the name suggests — the city’s lovely white-walled castle. It was built in 1543 by daimyo Mizukoshi Katsushige of the Maeda Clan, and has faced quite some trials throughout its existence, having been burnt down and rebuilt more than a few times. The current version only dates back to the mid-20th century, as it was dismantled during the Meiji era.
Nowadays, the castle is part of a city park which is a favorite local hangout, and the site of the Sato Memorial Art Museum which houses the private art collection of its namesake. During spring, the park is also one of the best spots in the city for cherry blossom viewing, especially along the banks of the castle moat.
Head up to the top of the reconstructed keep for a nice viewpoint across the city. It’s on the lower levels of these buildings that you’ll find the Toyama Municipal Folk Museum, which covers the history of the castle, city, and its people.
