Hitachi Seaside Park: A Floral Wonderland in Every Season (Hitachi sea side rail way is also great!!!)

Hitachi Seaside Park is a sprawling national park surrounded by flowers and greenery. With an expansive area of approximately 215 hectares, the park is divided into seven zones, each offering leisure spots and flower fields to enjoy amidst nature. Spring showcases flowers like narcissus, tulips, and nemophila. In summer, roses, zinnias, and sunflowers take the spotlight. As autumn arrives, the park transforms with kochia and cosmos, providing a visual delight for visitors.
