Hitachi Seaside Park is very large. The tour group dropped us off at the entrance near the sea (I just realized there are 4 entrances, east, west, south, and north). Walk a little to the right and you will find the famous blue butterfly flower hill. However, when I went there on 5/10, the flowers were withering, and it was raining, so the sea of flowers was not as beautiful, but it was still spectacular. There are other areas, and I actually walked around. My thoughts: I walked around once within the time I stayed there, and my legs were really broken. Ashikaga Flower Park is highly recommended and really worth a visit. Although the wisteria flowers are also withering, there are other flowers in full bloom in the park, such as roses, azaleas, and peonies, which amazed me. It can be seen that the entire garden is well maintained.
