Kochia Saitama City Omiya Hana no Oka

Hitachinaka Seaside resort is famed for its stunning kochia. Particularly in October when they are a flaming red. It is one of the famous autumn scenes of Japan. But you don’t have to go all the way to Northern Ibaraki to view this unusual bloom. We don’t have anything on the scale of Hitachinaka, but there are a few places you can see Kochia in Saitama.

Including the ever-colorful Omiya Hana No Oka park that straddles both Ageo and Saitama Cities. Apart from the Kochia, there are several other flowers currently in bloom in the park, and they even have a pumpkin patch for the season.

Kochia is a broadleaf plant which is often called Summer cypress, Mexican fireweed (or just fireweed), ragweed or burning bush. It is of the genus Bassia, with a scientific name of Bassia scoparia. Kochia is of the herb family Amaranthaceae.

Kochia in Japan

In Japan, Kochia is a popular annual for its longevity and ornamental value. It starts as a grape green color around August. In late September it starts to change to an orangey pink followed by a flaming pink. Finally, around early October, it becomes the blood red it is adorned for.


In Northern Japan the seeds of Kochia are used as a type of dressing called tonburi. The seeds of the plant are dried, boiled and prepared as a “chinmi” or delicacy of Akita prefecture. Due to its similar appearance to caviar it has been nicknamed mountain caviar.

Omiya Hana no Oka is a small, but picturesque, flower park that is on the border of Tosaki in Ageo and Nishi ward of Saitama City. There are several flower beds in the park that are maintained by local volunteers. You can enjoy flowers all year round thanks to their continued efforts.

The park is popular with families although it only has a small and old playground. There are some nice open green spaces where you can picnic and bikes are allowed. However, please note that pets are not allowed in this park. In summer, there is a large long gradated splash pad. There is a restaurant on the Nishi ward end of the park.

This year, 2019, some of the kochia in the park were unfortunately damaged by a typhoon in early September. However, they are still very impressive and worth a visit if you are in the area.

Pumpkin patch and kochia

It is one of the few parks that has a pumpkin patch too. You can’t walk among the pumpkin, just view them from a bridge. But there are some kochia beside the giant pumpkins.

At the moment, September 28th, the kochia are beginning to change from a grape green color to an orange pink shade. They remind me of the trolls characters when they are this color!
