Overview (history, characteristics, attractions)

Hitachi Seaside Park is a large-scale national recreational park located in Hitachinaka City, Ibaraki Prefecture. Its vast grounds are home to flower fields that change with the seasons, a grassy area, cycling trails, children's playgrounds, an exhibition hall, a cafe, and more, making it popular with families, couples, and photography enthusiasts.

The park's attractions include the "Nemophila (blue flower) Hill" in spring and the large colonies of "Kochia (a fluffy grass that turns red in autumn)" in autumn, which attract many visitors from both Japan and abroad, and the picturesque scenery is a major draw. Flower festivals are also held each season, featuring tulips, poppies, rape blossoms, and more.

Highlights

  • Miharashi Hill (Nemophila): A spectacular spot where the entire hill is dyed a pale blue in spring (best time to see from late April to early May). It is also famous as a photo spot.
  • Kochia Hill: In autumn (around October), the hills change from green to bright red, creating a spectacular sight. Perfect for strolling and taking photos.

Things to be aware of (crowds, manners, seasonal precautions, etc.)

  • congestion:The park is extremely crowded during peak seasons for nemophila (spring) and kochia (autumn). Weekends and public holidays are especially busy, so we recommend arriving early in the morning or visiting on a weekday.
  • Admission fees and event information:Admission fees, event schedules, and opening hours may change depending on the season and year. Please check the official website for the latest information.
  • Manners:Please be considerate of other visitors and plants by not entering flower beds or planted areas, taking your trash with you or disposing of it in designated areas, and following pet entry rules (restrictions apply depending on the area).
  • Clothes/preparation:The park is large and requires a lot of walking, so we recommend wearing comfortable shoes. It's a good idea to bring sun protection (hat, sunscreen) and drinks. Be aware of the chill in the mornings and evenings in spring and autumn, and the strong sunlight in summer.
  • Weather and best time to see the flowers:The best time to see the flowers varies from year to year (depending on the weather), so it's a good idea to check the "best viewing information" beforehand and make your plans accordingly.
  • Parking and Transportation:Parking lots can fill up during peak times, so consider using public transportation or leaving early.

Finally, Hitachi Seaside Park is a beautiful park that changes its appearance with each season. The scenery is particularly spectacular during the flower season, but please be mindful of crowds and follow the rules to ensure a comfortable and safe visit. Be sure to check the official website for the latest opening information, access, and events.
