Hitachi Seaside Park

Hitachi Seaside Park is a 190-hectare public park located in Hitachinaka, Ibaraki Prefecture, approximately 120 kilometers northeast of Tokyo. The park was established in 1991 on land that previously served as a United States military training facility after World War II. Following the return of the land to Japan, it was transformed into a sprawling recreational space designed to showcase seasonal flowers and provide outdoor activities for visitors throughout the year.

The park's primary significance lies in its carefully cultivated flower displays that change with the seasons, creating dramatic landscapes of color across its rolling hills. The most iconic feature is Miharashi Hill, where approximately 4.5 million baby blue eyes (nemophila) bloom each spring, covering the hillside in a striking blue carpet that contrasts with the sky. In autumn, the same hill transforms with over 32,000 kochia bushes that turn brilliant crimson red, creating an equally impressive spectacle. The park also features millions of daffodils, tulips, and cosmos flowers during their respective seasons.

Visitors can explore the park through extensive walking and cycling paths, with bicycle rentals available at the main entrance. The park includes numerous themed gardens, including a rose garden, rock garden, and a large pleasure garden area with an amusement park featuring a Ferris wheel and other rides suitable for families. The Seaside Train, a trackless vehicle, provides transportation around the park's vast grounds for those who prefer not to walk long distances.

Access to Hitachi Seaside Park is most convenient from Katsuta Station on the JR Joban Line, which takes approximately 90 minutes from Tokyo Station. From Katsuta Station, visitors can take the Ibaraki Kotsu bus bound for Ajigaura, which reaches the park's main entrance in about 15 minutes. During peak flower seasons, particularly Golden Week in early May and weekends in October, direct buses run from Tokyo Station to the park. General admission costs ¥450 for adults, with separate fees for the pleasure garden area. Parking is available for those traveling by car, with fees of ¥510 per vehicle.
