History of Hitachi Seaside Park

The Showa Period: As an Aviation Base

The land that is currently Hitachi Seaside Park was formerly called the Mito-Higashi Airbase, and was a military facility owned by the Imperial Japanese Army. After Japan's surrender in 1945, the land was confiscated by the United States to become a bomb-training ground for the US Air Force. Inhabitants of the area were not pleased; bombing drills and stray dud shells falling on the surrounding region brought an uproar of dissatisfaction from residents.

Rallying the entire prefecture, the regional government of Ibaraki began to continuously request the United States Air Force to return the airbase to its locale. After over 10 years of demanding reversion of the land, it was in 1973 that it was finally returned to the Japanese government. The strong desire of the local population to turn the land into a park, as a symbol of peace, compelled the construction of Hitachi Seaside Park.

The Heisei Period: The Creation of Hitachi Seaside Park

Planning and construction took place between 1979 and 1990, and removing unexploded bombs from underground was also a large part of the procedure. The park, though not fully complete, opened in 1991, with parts of the parks opening throughout the upcoming years. Sports facilities such as cycling areas and BMX courses opened as well, making the park available for a ubiquitous outdoors experience. Currently, 57% of the entire area is open to the public, with the remaining area being a forest zone.

7 Must-See Areas to Fully Enjoy the Park

1. Miharashi Area

The Miharashi Area is in the northeastern area of the park. The area's Miharashi Hill has the highest elevation in Hitachinaka City, and is most famous for the seasonal sceneries created by the field's nemophila and kochias. The sky-blue nemophila field blooms from late April to mid-May, and the flowers unify with the sky and ocean to create a stunning panorama of blue. In the fall, kochia and cosmos paint Miharashi hill a fiery red and delicate pink. The hill not only gives a great view of Hitachi Seaside Park, but also of the Pacific Ocean, making it a goldmine of picturesque sceneries and a hugely popular photo spot,

Also in the area is one of the oldest "minka", or a traditional Japanese house, in eastern Japan. Visitors are allowed to explore its interior too, and right beside it is "Miharashi-no-Sato", or Miharashi Village. Miharashi Village was created to present park guests with the nostalgia of old-fashioned agricultural village life. To match the scenery, plants such as rapeseed flowers, zinnia and buckwheat are planted.

2. Forest Area

In the green, northern end of the park is the Forested Area characterized by a dense covering of Japanese pine trees. Although a portion of the area is designated as a plant life preservation area, the rest allows visitors to see the forest's diverse natural ecosystem up close.

The nearby Sawada spring water area is a great place for a stroll while exploring Hitachi Seaside Park's nature. The spring water is a unique result of the area's geological properties. Under the surface soil is a thick layer of sand, which is underlaid by another layer of much less permeable soil. Under this setting, rainfall that seeps into the ground is stopped by the deep non-permeable layer of soil, and brought back up to create a natural freshwater spring.

Next to the area, you will find the "Sawada Spring Water Nature House" that has many informative exhibits to teach visitors about water retention basins and their ecosystems.

3. Grassland Area

The vast stretch of land in the heart of the park is the Grassland Area. Approximately 8ha of lawn sprawls across the area, with athletic fields, cycling courses and barbeque venues ready for use. Whether you are the active kind who loves running around in the fields, or one that prefers a relaxing sunbathe on the grass, this area will meet your needs.

The neighboring "Grassland Flower Graden" has a different scenery of flowers with every season. Poppies and linaria cover the space from spring to early summer, while a cosmos field takes over in autumn. There is a cycling course right next to it too, so a bike excursion surrounded by these beautiful flowers is a great idea too.

4. Dune Area

The Dune Area locates along the coast of Hitachi Seaside Park, and displays a great number of coastal vegetation. The "Dune Garden" houses and nurtures around 60 types of coastal plants, alongside 130 types of herbs and succulent plants. Nearby, the "Green Studio" hosts gardening events, and the Ceramic Arts Studio holds ceramic-making classes every month on the third Sunday.

5. West Entrance Area

The "West Entrance Area" right next to Hitachi Seaside Park's west entrance, is a place popping with color and energy. The "Tamago-no-Mori Flower Garden" nurtures 250,000 tulips of 143 types, creating a scenery of blinding vividness. Even when compared to the Netherlands' Keukenhof Park, the world pinnacle of tulip fields, this garden is nothing to scoff at.

"Tamago-no-Mori" means "forest of eggs". Its construction attempted to convey a theme, which was "a forest in which eggs can grow safely in their nests, hatch, and grow healthily until they flutter off". The pine forest here was laid out with lower elementary school-age children in mind, and the 9 colorful eggs in the area comprise the children's playground.

The History Gallery here educates visitors on the history of Hitachi Seaside Park. Informative exhibits teach the park's bumpy road to construction through words, while other displays such as real undetonated shells from the airbase days, show it through their striking visuals.

6. South Entrance Area

Pass through the welcoming Aka no Gate (red gate) and enter through the South Entrance. The South Entrance area is home to the remarkable sunflower field in the Izumi-no-Hiroba Flower Garden, right by the Fountain Plaza, and is a perfect place to feel the coming of summer. Visiting after the sunflower season will nonetheless put you in awe as well, as you are greeted by the fall foliage of metasequoia, and it creating a whole new landscape for your eyes.

7. Pleasure Garden Area

The southwest segment of the park is none other than the Pleasure Garden Area. As the name infers, the Pleasure Garden Area is decked with amusement facilities. With a 400 meter-long slide, and a BMX course, the area is calling for adventure seekers and fun lovers. In the summer time, a water park opens its gates to many excited families and children! Alongside the amusement venues is the triple-themed "Hitachi Rose Garden" that was completed in 2014.
