The park utilizes an automated irrigation system to maintain the vast swathes of nemophila during the dry spring season.
The iconic Kochia bushes are annual plants that are replanted every year specifically for the autumn display.
The park is divided into seven distinct areas, including the West Entrance Zone, South Entrance Zone, and the Dunes Garden.
A portion of the park is preserved as a sand dune ecosystem to protect native coastal vegetation.
The park's soil composition was significantly altered after its conversion from a military site to support intensive floral horticulture.
Hitachi Seaside Park is a massive public recreational space in Hitachinaka, Ibaraki, renowned for its rolling hills of seasonal flowers. The Miharashi no Oka hill is the park's primary feature, carpeted with millions of Nemophila (baby blue eyes) in spring and Kochia bushes that turn fiery red in autumn. The park covers approximately 200 hectares of developed land, featuring a mix of flower gardens, a pine forest, and sand dunes. A dedicated 11-kilometer cycling trail winds through the grounds, providing access to diverse topographical zones. Additional amenities include the Pleasure Garden area with an amusement park and various sports facilities. The park was originally part of a US military firing range before being returned to the Japanese government and developed for public use.
