Hitachi Seaside Park — A Seasonal Floral Wonderland by the Sea

Sprawling across a planned area of about 350 hectares along the coast of Hitachinaka City, Ibaraki Prefecture, National Hitachi Seaside Park is one of Japan's most spectacular floral destinations, where flowers of every season transform the landscape into living paintings. The park is most famous for its fields of nemophila (baby blue eyes) that carpet the rolling hills each spring in an ethereal ocean of blue, and for the crimson kokia bushes that blaze across the slopes every autumn. Its location near the sea, where you can stroll while feeling the refreshing breeze of the Pacific, is another part of its charm.

Note: This page is a roundup that introduces representative sightseeing spots in Ibaraki together. Centered on Hitachi Seaside Park, use it alongside other regional highlights such as Fukuroda Falls and the Izura coast to help plan your trip.

Highlights

• Miharashi-no-Oka (nemophila): From mid-April to early May, the entire hill is covered in blue nemophila, unfolding a fantastical scene where they merge with the blue sky and sea. It is nationally famous as a "blue spectacle."
• Miharashi-no-Oka (kokia): Around mid-October, the whole hill is dyed brilliant red by the autumn kokia, popular as an autumn scenic spot.
• Dune Garden: A vast flower field where spring blooms such as tulips and daffodils seem to compete with one another.
• Pleasure Garden: Well-equipped with rides such as a Ferris wheel and merry-go-round. Popular with families.

Practical Travel Notes

Spring (March to May) brings a relay of flowers, from daffodils to tulips to nemophila, and is the busiest season. Summer (June to August) sees sunflowers and other blooms, and you can stroll leisurely in the sea breeze. Autumn (September to November) features cosmos and the red kokia foliage. In winter, illumination events are sometimes held depending on the period. During the peak nemophila season (Golden Week from mid-April to early May), the morning right after opening is relatively uncrowded, letting you enjoy the blue spectacle at leisure. The park is large, so renting a bicycle or riding the Seaside Train is convenient.

A Word of Advice

The peak nemophila season (Golden Week from mid-April to early May) is very crowded, and lines can form before opening. Plan your visit after checking the flowering status on the official website. The parking lots are large, but they can fill up on some days, so an early morning arrival is recommended. The park is spacious and requires walking to reach Miharashi-no-Oka, so comfortable shoes are essential.
