Hitachi Seaside Park

Hitachi Seaside Park (国営ひたち海浜公園, Kokuei Hitachi Kaihin Kōen) is a vast national flower park on the Pacific coast of Ibaraki Prefecture, in the city of Hitachinaka in the Kantō region. Spread across some 190 hectares of former military and industrial land near the sea, it has become one of Japan's most photographed gardens — celebrated worldwide for the rolling hills of flowers that change colour with the seasons.

The park's most famous spectacle is Miharashi Hill, which in spring is carpeted with around 4.5 million nemophila (baby-blue-eyes), turning the whole slope a soft sky blue that seems to merge with the horizon and the ocean beyond. The same hill is set ablaze in autumn by kochia — bushy summer cypress that grows in tidy mounded rows, glowing brilliant green in late summer and turning a fiery crimson in October. Between these headline displays the park cycles through tulips, daffodils, poppies, roses, cosmos, sunflowers and zinnias, so there is colour for much of the year.

Hitachi Seaside Park is more than flowers: it includes a small amusement park with a Ferris wheel, broad cycling paths, woodland, dunes and grassy plains, making it a relaxed full-day outing for families and garden-lovers alike. The flagship times to visit are mid-to-late April and Golden Week for the nemophila, and October for the kochia; the park can be very crowded in those windows. Winter is quiet, with seasonal illuminations.

By Plane

Ibaraki Airport (IBR) is the nearest airport, with connections to several Asian cities and within Japan; from the airport, transfer toward Katsuta / Hitachinaka. Travellers arriving via Tokyo's Narita or Haneda airports usually transfer to the JR Jōban Line.

By Train

The gateway station is Katsuta Station on the JR Jōban Line, the next major stop after Mito heading north. From Katsuta Station, regular buses run to Hitachi Seaside Park in about 15–20 minutes. From Tokyo, take a limited express on the Jōban Line from Ueno to Katsuta, then the bus.

By Car / Road

The park is reached by car from the Tokyo direction via the expressway network along the Jōban corridor, with the Hitachi-Kaihin-Kōen interchange close by. The park has large car parks, but in the peak nemophila and kochia seasons they fill early and traffic builds up — arriving early is strongly advised.

The park is large, so plan your visit. Getting around the grounds is easiest by the Seaside Train, a tractor-pulled road train that loops the park with several stops (a small fare applies, with day passes available), and by rental bicycle — the park has extensive dedicated cycle paths and bike-hire facilities. Walking is enjoyable for shorter circuits, but covering the whole park on foot takes time. There is no internal scam risk; fares are fixed.

• Miharashi Hill (みはらしの丘) — The park's signature: a broad rolling slope blanketed in roughly 4.5 million nemophila in spring (a sea of sky blue) and in mounded kochia that turns crimson in autumn. The view from the top reaches to the ocean.
• Tulip Garden — Thousands of tulips bloom around a small pond in April, alongside daffodils.
• Seasonal flower fields — Across the year the park stages poppies, roses, cosmos, sunflowers and zinnias in successive displays.
• Woodland and dune areas — Stretches of pine woodland, coastal dunes and open grassland that give the park its varied, restful landscape.

The headline activity is simply walking and cycling among the flower fields, timed to whichever seasonal display is at its peak — nemophila in spring, kochia in autumn, tulips in April. The park's Pleasure Garden amusement area has a large Ferris wheel and family rides. The extensive cycle paths make for a relaxed loop of the grounds, and the woodland and grassy plains are good for picnics. The park also hosts seasonal events and, in winter, illuminations. Photography is a major draw — the flower hills are among the most-photographed scenes in Japan.

The park has several restaurants, cafés and food stands across its grounds, serving everything from light meals and curry to soft-serve ice cream and seasonal snacks; flower-season pop-up stalls add to the choice.

• Park cafés and food courts offer casual meals, noodles, curry and snacks in the budget-to-mid range; vegetarians will find some options.
• For a fuller meal, the city of Hitachinaka and nearby Mito have a wider range of restaurants — Ibaraki is known for nattō and, on the coast, fresh seafood.

Park cafés and stands serve coffee, soft drinks, seasonal flower-themed beverages and soft-serve ice cream. Amazake and green tea are common non-alcoholic options. The tap water is safe to drink.

There is no lodging in the park; visitors stay in the surrounding cities.

• Budget: Business hotels around Katsuta Station and in Hitachinaka offer modest rates.
• Mid-range: Mid-tier business hotels in Hitachinaka and Mito provide comfortable stays with good rail access.
• Upscale / heritage: Larger full-service hotels in Mito, and seaside accommodation along the Ibaraki coast, offer a more upmarket option.

The park's shops and the facilities near the entrances sell flower-themed souvenirs, postcards and local Ibaraki products. Nearby Hitachinaka and Mito offer fuller shopping, including Ibaraki specialities such as nattō products and sweet potato goods. Prices are fixed; bargaining is not customary in Japan.
