The illuminated Kokias in Summer are wonderful as well as the red colored ones in Autumn. They seem to dance with lights and music. Why don't you spend a good night in the sea breeze? (the park is near a sea)

Now, people from not only Japan but also all over the world visit here without a break. Miharashi Hills have proudly blooming nemophilas with so wonderful blue view at Hitachi Seaside Park in Ibaraki. I want you all to visit here at least once, because it's the best one among tourist attractions.

Twilight is the best time to see the red colored kochia, bassia scoparia. It was a little cloudy when I took the photos but this year, the bright red sky after sundown and kochia will be seen together! Can't wait!

Wonderful Landscape! Nemophila Blue Spreading All Of Your Sight

At Miharashi Hills of a flowery theme park, HITACHI SEASIDE PARK. The landscape of 4.5 million nemophila flowers is surely wonderful!! Around Golden Week Holidays this year (from the end of April to the beginning of May) could be the best season to see! Why don't you visit?
Nemophila Harmony is going to held from 4/21-5/13 in 2018.

A Large Park With Nemophila Expanding Like Ocean & Various Spring Flowers

Hitachi Seaside Park is very large! The blue flowers expanding like ocean at Nemophila's Hill, and even the tulips blooming between the trees are wonderful! Both walking and cycling could be nice, please enjoy these flowers thoroughly.
Access: take train to Katsuta Station, then you can go to the park by bus or car. By the way, Nemophila's Hill is so crowded that it's difficult to take pictures without people. And, this park is very large, so you can rent a bicycle if you don't have much time.

Collaborated Illumination Of Sunflowers And Kochia

The light-up for only 10 days. You can enjoy the collaboration of lights and music of Disney and Ghibli! From the angle you can see the sunflowers and kochia together.

Lighted Kochia Only In Summer

The green kochia is lit up for only about one week in summer. There're less people than that in the season of Nemophila flower, and I could enjoy them leisurely.
