The castle is Moving! – Renovation of the Hirosaki Castle Inner Courtyard Stone Walls ―

To facilitate repairs, the castle tower will be moved after the 2015 Cherry Blossom Festival.
2015 will be the last year (for a while) to see the familiar scenery of the castle, bridge, and cherry blossoms.
- Early 2015: Send-off for the familiar scenery
- From 2016: New scenery for a limited time
(A fantastic view of snow-covered Mt. Iwaki, cherry blossoms, and the inner courtyard together!)
