Hitachi Seaside Park and Aqua World Oarai are about a 20-minute drive apart. You can use the combo ticket on different days, but it's also possible to visit both in one day. We recommend enjoying the nemophila in the morning and then spending a relaxing afternoon at the aquarium.
In the surrounding area, you'll find dining facilities such as the Nakaminato Fish Market, as well as breathtaking coastal viewpoints. Make the most of your trip this spring in the Hitachinaka and Oarai area by taking advantage of the set tickets available!
