Q&A about kochia

What is kochia?

Kochia is called houkigusa in Japan, which means plants for making brooms after being aired. The nutshells are called tonburi that are edible. Especially people in Akita Prefecture like to eat tonburi, which is praised as “caviar” from fields. However, the kochia in this park are grown not for food but for appreciation.

Do the park staff sow the seeds?

No, they don’t. They plant seedlings that are grown to 10 to 15 cm tall, and each seedling is planted on the hill all by hand.
