Takiyama Park
This park is also known as the site of Takiyama Castle, a stronghold of the Hojo clan during Japan's Warring States period. The castle ruins, now designated a National Historic Site, and the surrounding area feature walking trails where visitors can experience the site's history.
Besides cherry blossoms, the azaleas here are beautiful too! The only downside is the transportation—it's a bit inconvenient since you have to take a bus to get there.
