Approximately 12 million cosmos grow on the Arakawa riverbed near “Cosmos Arena Fukiage” in Konosu annually in autumn. During the period of the bloom there is usually a two day cosmos festival. However, in 2019 the festival was cancelled due to typhoon Hagibis and in 2020 the festival was cancelled due to the pandemic. On September 22nd 2021 the Konosu Tourism Assocation officially declared that the festival will not be on, for the third year in a row, in 2021 either. However, the flowers have bloomed and it is okay to visit them so long as you wear a mask and practice social distancing.
In 2020, it was a much smaller display than ‘normal’, but this year there seems to be the full 12 MILLION again. We visited on September 25th 2021 and the orange / sulphur cosmos are already in full bloom. The other colors of cosmos are also coming along nicely. There are some areas where the other colors of cosmos (white, purple, pink etc) have not flowered yet, but there is one large section where they have already started to flower. They say the best time to see the cosmos in Konosu is mid to the end of October.
However, if you do visit the end of September or early October, you can also see sunflowers nearby at “Hana no Oasis”. It is a community garden, also in Konosu city. The “flower bus” links them both, or if you are driving it takes about 15 minutes between the two locations.
Cosmos Festival in Konosu
In a non pandemic year there is normally a two day festival in celebration of the millions of cosmos. It is held close to the flower fields. It normally takes place toward the end of October, often the weekend of the third week in October.
During this period that you are allowed walk on Japan’s longest water pipe bridge (weather permitting) to view the flowers from above. Normally, the water pipe bridge can be accessed between the hours of 9.30 am and 3 pm. However, this does not seem to be an option in 2021 as the festival is not on. In addition, in a ‘normal year’ the festival includes stage events, a farmers market, festival stalls and a flea market. Moreover, this is a free event.

The cosmos fields are a five minute bus ride on the “Flower Bus” （フラワーバス）from JR Takasaki Line Fukiage station （ＪＲ高崎線吹上駅). The bus goes toward Kita Kounosu (北鴻巣行き). The stop for the flowers is called Cosmos Arena Fukiage （コスモスアリーナふきあげ）.
The cosmos fields are 11 kilometers from the Higashimatsuyama Interchange of the Kanetsu Expressway. You can park in front of Cosmos Arena Fukiage for free. It is the closest car park to the larger displays. Map at the bottom of the post.
Konosu has a lot of famous events on over the year as well as some other low key ones. Among their annual famous events are the Guinness World Record holding Konosu Fireworks and Japan’s tallest Hina (Doll) display:
