Bright red kochia

Autumn at Hitachi-Seaside Park

At the National Hitachi Seaside Park in Ibaraki Prefecture, bright red kochia can be seen in autumn. The sight of approximately 40,000 bright red kochia plants spreading across the hills is breathtaking, almost like a painting, and has become a popular spot that attracts tourists not only from across Japan but also from around the world.
Kochia is an annual herb belonging to the family of the daylily (formerly known as the family of the broomrape), and its native country is Asia. Its Japanese name is "broom grass," and in the past, its stems were dried to make brooms. The fruit is called "tonburi," or "caviar of the field," and is popularly known as "caviar of the field. (The lime green kochia, which grows in the summer sun from early July, has a lovely round shape and is soft to the touch. This year, approximately 40,000 green-leafed kochia will begin to change color in early October, turning Miharashi no Oka bright red by mid-October. The "beautiful color change" of the kochias, which are the main attraction, together with the cosmos and buckwheat flowers at the foot of the hill, create an autumn-colored landscape. During the event, visitors can enjoy the changing colors of the kochia, gourmet foods available only during this season, and craft events to fully enjoy the appetite, art, and autumn.


Kochia showing various expressions

As they grow, they change size and color. The charm of kochia lies not only in its color, but also in its unique shape and size, even though they may look the same one by one! Kochia also changes its appearance depending on the time of day, giving a fresh impression in the morning and becoming even more vivid in the evening in the western sun. Kochia is not only bright red in the autumn foliage! Kochia can be enjoyed all year round.

Early October

The kochia stops growing at about 70 cm. The fuzzy appearance of the kochia attracts visitors who come to view it! From this point on, the color changes to red, and visitors can enjoy the gradation of colors during this period. Kochias do not suddenly turn bright red, but rather turn red little by little, starting from the top of the head. The gradation of red and green colors is vivid during the period until all kochia turn bright red. This is a precious period when you can observe the kochia's reddish hue increasing day by day. Miharashi no Oka is the best viewing point!
