Visitors can explore the reconstructed castle structures, stroll through the beautiful gardens, and visit the Momijiyama Garden, a traditional Japanese landscape garden within the park.
Entry to Sumpu Castle Park is free. However, there may be a small fee for certain areas or activities, such as entering the Momijiyama Garden or participating in special events.
Most of the original structures were destroyed over time, but the park has reconstructed some key features, including the East Gate (Higashi Gomon) and the Tatsumi Yagura watchtower, offering visitors a glimpse into the castle's past.
