Nemophila Blooms at Hitachi Seaside Park

At Miharashi-no-Oka (Panorama Hill) in the National Hitachi Seaside Park in Hitachinaka City, Ibaraki Prefecture, approximately 5.3 million nemophila flowers carpet the entire hillside in soft, pale blue each spring, making it one of Japan's most spectacular floral destinations. The breathtaking sight of blue flowers merging seamlessly with the blue of the ocean and the sky draws visitors from across Japan and beyond each year, cementing this park's reputation as one of Ibaraki's defining springtime icons.

About National Hitachi Seaside Park

National Hitachi Seaside Park is a vast government-managed park facing the Pacific Ocean. Its planned area reaches about 350 hectares. The land, once used as a bombing range by the former Japanese Army and later the U.S. military, was transformed into a public park celebrated as a park of flowers for its seasonal blooms across all four seasons. The park features attractions such as a Ferris wheel, cycling courses, and barbecue areas, making it a popular spot where you can enjoy nature and leisure all day long.

The Hill of Nemophila and Kokia

The nemophila covering Miharashi-no-Oka is a signature scene of spring. The entire gentle hill is dyed a clear blue, and looking out from the hilltop, a fantastical panorama unfolds in which sky, sea, and flowers become one.

In autumn, the same hill is covered with kokia (burning bush), and the rounded green kokia shrubs turn a fiery, brilliant red. Showing completely different spectacles in each season is another great charm of this park.

Access and Basic Information

Opening hours are generally from 9:30 a.m. to 5:00 p.m., and may be extended in some seasons. Closed days are every Tuesday (the following day if a national holiday) and the year-end and New Year period, among others. Because a seasonal surcharge is added during certain periods, admission is higher than usual during the nemophila and kokia seasons. By public transport, take a local bus from bus stop 2 at the east exit of Katsuta Station on the JR Joban Line: about 15 minutes to the West Gate and about 20 minutes to the South Gate. By car, it is right by the Hitachi Kaihin Koen Interchange on the Joban Expressway. During peak flowering, the entrance gates and parking lots become very crowded, so an early arrival is recommended.

Practical Travel Notes

• Recommended season and time of day: Nemophila peaks from mid-April to early May, and kokia turns red around mid-October. Golden Week is especially crowded, so arriving in the morning right after opening lets you enjoy the blue spectacle in relative calm.
• Avoiding crowds: On peak weekends and during Golden Week, lines can form at the entrance gates before opening. The trick is to check the official website's flowering status and aim to arrive by opening time.
• Estimated time needed: For Miharashi-no-Oka alone, allow one to two hours; to explore the flower fields and attractions thoroughly, plan for half a day to a full day.
• Getting around and real attractions: The park is enormous, so renting a bicycle or riding the park's Seaside Train helps you get around efficiently. Spring flowers such as tulips and daffodils, and the Pleasure Garden with its Ferris wheel, are also worth seeing.

A Word of Advice

Miharashi-no-Oka is open and windy with nothing to block the wind, so a jacket and a sun hat will keep you comfortable. Both the West and South Gates require walking to reach the hill, so wear comfortable shoes. Since a seasonal surcharge applies during some periods, check the latest fees on the official website.
