Hitachi Seaside Park is a 190-hectare public park located in Hitachinaka, Ibaraki Prefecture, approximately 120 kilometers northeast of Tokyo. The park was established in 1991 on land that previously served as a United States military training facility after World War II. Following the return of the land to Japan, it was transformed into a sprawling recreational space designed to showcase seasonal flowers and provide outdoor activities for visitors throughout the year.

The park's primary significance lies in its carefully cultivated flower displays that change with the seasons, creating dramatic landscapes of color across its rolling hills. The most iconic feature is Miharashi Hill, where approximately 4.5 million baby blue eyes (nemophila) bloom each spring, covering the hillside in a striking blue carpet that contrasts with the sky. In autumn, the same hill transforms with over 32,000 kochia bushes that turn brilliant crimson red, creating an equally impressive spectacle. The park also features millions of daffodils, tulips, and cosmos flowers during their respective seasons.

Visitors can explore the park through extensive walking and cycling paths, with bicycle rentals available at the main entrance. The park includes numerous themed gardens, including a rose garden, rock garden, and a large pleasure garden area with an amusement park featuring a Ferris wheel and other rides suitable for families. The Seaside Train, a trackless vehicle, provides transportation around the park's vast grounds for those who prefer not to walk long distances.

Access to Hitachi Seaside Park is most convenient from Katsuta Station on the JR Joban Line, which takes approximately 90 minutes from Tokyo Station. From Katsuta Station, visitors can take the Ibaraki Kotsu bus bound for Ajigaura, which reaches the park's main entrance in about 15 minutes. During peak flower seasons, particularly Golden Week in early May and weekends in October, direct buses run from Tokyo Station to the park. General admission costs ¥450 for adults, with separate fees for the pleasure garden area. Parking is available for those traveling by car, with fees of ¥510 per vehicle.

It was nice but not as expected, not like what it looks in the ad or pictures online so lower your expectation. Though, they have a large variety of plants and flowers which are distinctive for each season so you can come at anytime. Its a huge place, they not only have gardens but also an amusement park. The place has its own food stands so you dont have to prepare food in advance but idk ab the price.

One huge park by the sea. I simply went to see the marvelous kochia hill, but it turned out the park has so much to offer. Absolutely great for families. Has lots of various activities, from a simple picnic, bike riding, and a mini theme park. Even just enjoying the beautiful vista is already joyful. It’s almost 2 hours from Tokyo Station by train and continued with a local bus from Katsuta Station (appr. 17 minutes). Plenty of food and beverages vendors inside, but be prepared for the lines during weekend/holidays.

Hitachi Seaside Park is famous for its blue nemophila that bloom between mid-April and May. And the red kochia trees after mid-October. It offers many attractions with entertainment. Such as golf putting, biking, and other things for everyone. This was our first experience in this beautiful part. We enjoyed the cute red trees that transformed into a red color. We liked the rides in the amusement park as well. However, it would be nice if all the information were given a little bit more clearly. For example, the Ferris wheel. We were in line at the Ferris wheel for about 10-15 minutes already until we saw someone cut the line. We realized that we were in the wrong line. Moreover, the information for the one-day pass option for unlimited amusement rides should be at the entrance. One complaint is that all the paper tickets you need are inconvenient to hold on to and use. We held six different tickets while visiting the park. Perhaps if they combine all the tickets into one, everyone will benefit from this in the future. A small reminder, this place is near the ocean. That means there are strong winds so I would suggest that you bring a warm jacket with you.

A beautiful place! Easy to find, large carpark and was relatively cheap. I went to see the flower park but was happy to find out it has an amusement side, the array of food vendors,large gardens and various amusement rides made this a very pleasant experience. Food was reasonably priced, entry too! I would highly recommend for anyone to visit!
