Kokai River Park & Poppy Fields

This riverside is split into fours zones: the Nature Observation Zone, Sports Zone, Nature Center, and Flower Zone.
The Kokai River is famous for fields of poppies that bloom from mid-May onwards. Over two million poppies fill the park with color. This striking sight is paired with the stunning backdrop of Mount Tsukuba.
There is also a range of activities, such as golfing and cycling, available around the park.

Aoki Sake Brewery

Founded in 1831, Aoki Sake Brewery is currently the only sake brewer in Koga City that performs all of the operations from brewing the sake to selling and also continues to preserve the local flavor. The building, a merchant-style structure with a doma (earthen-floor entrance), is over 100 years old, and the red brick walls, common in Koga—a region historically known for brick production—create a nostalgic atmosphere, as if stepping back in time. Sake made from local rice such as Nipponbare and Hitachi-Nishiki, grown in the rich soil of Ibaraki Prefecture, all have a crisp taste and have won them numerous awards in Japan.
There is also a store, and you can visit the brewery and taste the sake, so please inquire in advance.
