cosmos fukiage konosu

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.

  1. Such a shame that the festival isn’t on, nice that you can still visit the flowers and they didn’t just mow them to prevent people from turning up.

    Hopefully everything can go back to normal soon.

    1. Yes, thank goodness they didn’t mow them down! Last year, they had a smaller display, so its great that they at least grew millions again this year to cheer us all up! Pretty phenomenal numbers eh!

      1. “Millions of flowers…” in a Doctor Evil voice.

    1. Thanks Ian. They are definitely worth visiting, so beautiful. And there are also sunflowers blooming nearby (15 minute drive)… I just added info for those tonight. 🙂

  2. Seriously – you are the best. I’m so glad you didn’t give the blog up
