The park features a dedicated monument marking the 'Perry Road' historical connection to the arrival of the Black Ships.
Its hilltop elevation provides a panoramic view of the 'Ebisu-jima' island and the mouth of the Inazusa River.
The park grounds serve as a transition zone between the city's urban district and the rugged coastal nature of the Izu Peninsula.
Shimoda Park is a hilltop public space situated on the site of the former Shimoda Castle, built by the Hojo clan in the 16th century. It is most notable for its extensive collection of over 150,000 hydrangea bushes that bloom across the park grounds in early summer. The park offers elevated vantage points overlooking Shimoda Port and the surrounding Izu Peninsula coastline. Historical stone walls and earthworks from the original castle fortifications remain visible throughout the area. It features a network of paved walking trails that wind through dense wooded areas and flowering gardens. The park commemorates the historical arrival of Commodore Matthew Perry and the opening of Shimoda to international trade. Several monuments and stone tablets are installed along the paths detailing local maritime history. The site serves as a public observation deck for viewing the convergence of the Pacific Ocean and the town's harbor.
