A park that was once a castle, but now only the giant stone wall remains. Paper lamps are lit up during the Sakura festival in the night, turning it into a majestic scenery. And near the vicinity, there's a famous spot right at the front of Morioka District Court where a large stone was split in half by a blooming Sakura tree. Famously known as the "Ishiwari-sakura tree". Best time to visit: Mid to late April.
