Hitachi Seaside Park Guide: Best Time to See Nemophila & Kochia in Japan

Visiting Hitachi Seaside Park Access, Amenities, and Blooming Flowers Guide Excursion

Located along the Pacific coast in Ibaraki Prefecture, Hitachi Seaside Park is one of Japan’s most breathtaking flower destinations.

Interestingly, this peaceful park has a unique history. The area was once used as a military airfield and later as a U.S. bombing range after World War II. Following strong requests from local citizens, it was eventually transformed into a national park—now filled with beauty instead of conflict.

Today, the park spans an impressive 350 hectares, featuring flower fields, forests, and wide open spaces where visitors can enjoy nature throughout the year. There’s even a small amusement park and cultural facilities, making it a great destination for all ages.


A Hill Transformed: Miharashi no Oka

One of the park’s highlights is Miharashi no Oka Hill, a 30-meter-high hill that has been completely transformed from its past into a stunning seasonal landscape.

Once the target area for bombing practice, it is now covered with flowers that change with the seasons—symbolizing peace and renewal.


Best Time to Visit: Seasonal Highlights
