Hirosaki Castle was constructed back in 1611. The castle and the surrounding park opened as Hirosaki Park in May 1895 and has been enjoyed by many locals and visitors ever since.

The castle keep, five castle gates, and three corner turrets that have remained from the Edo period (1603-1867) are designated as National Important Cultural Properties.

Hirosaki Park is home to approximately 2,600 cherry trees of 52 varieties, making it one of the "Three Best Cherry Blossom Viewing Spots in Japan. There are many highlights, such as somei-yoshino, the oldest cherry tree in Hirosaki Park that is 140 years old, the illuminated yozakura (cherry blossoms at night), and "hanaikada," or flower rafts of cherry petals that cover the entire moat. The Hirosaki Cherry Blossom Festival, held every year from late April to early May, attracts many people from within and outside of the prefecture.

Currently, Hirosaki Castle's keep is being moved to the inner side of the castle's main citadel for repairs to the stonewalls, and for this limited time only, visitors can enjoy taking pictures of the keep and the cherry blossoms together with Mt. Iwaki.

In autumn, about 1,000 maple trees and 2,600 cherry trees turn brilliant colors, and chrysanthemum decorations and floral art adorn the site in the Hirosaki Castle Chrysanthemum and Autumn Leaves Festival. In winter, about 150 snow lanterns and snow statues handmade by citizens and about 300 miniature kamakura (Japanese igloos) lit with lights create a fantastic world in the Hirosaki Castle Snow Lantern Festival, offering beautiful seasonal scenes.
