Kawazuzakura at Cosmos Arena Fukiage Konosu

Information for early spring flowers and the 2024 Fukiage Poppy Festival at Cosmos Arena Fukiage. Which, as the name suggests, is best known for its cosmos. But they bloom in Autumn. This post focuses on a selection of the spring flowers you can see at the venue, including kawazu (early blooming) cherry blossoms, which are currently in bloom. Not full bloom yet, but around 40 to 50%. A couple are at around 70%.

Fukiage Flowers

  • Kawazuzakura – end of February to early March
  • Canola flowers – end of February to around early April
    • Dolls’ Display
  • Cherry Blossoms – around the end of March
  • Poppies – roughly end of April to mid May, it will depend on the weather
  • Mugi Nadeshiko aka Corn-cockles – around May
  • Cosmos have a post of their own


There are at least 20 trees, maybe 25 to 30, at Fukiage Cosmos Arena. They are behind the gymnasium and sports grounds, on the side of a hill. They line either side of one of the footpaths. Currently this venue is still off the beaten path for the fluffy pink blossoms – a secret spot where you can enjoy the view with few other (if any) people around. Moreover, this is a rare location where you can see the pink cherry blossoms contrasted by vibrant yellow canola flowers:

Canola flowers

There are canola flowers on the same hill as the kawazuzakura. As of February 28th 2024 they are still sparse, but there were some mature ones in bloom. Moreover, there are millions of canola along the embankment that overlooks the Arakawa Riverbed. They’ve only started to get some height on them, so it might take a week or so for a more dramatic look. Both photos were taken today. The one on the left is overlooking the Arakawa Riverbed and the one on the right at the back of the gymnasium beside the early blooming cherry blossoms.

Dolls Display

Around the time the kawazu and canola start to bloom the gymnasium has a dolls’ pyramid. It is one of six displays of the much larger Konosu Surprising Dolls Festival. Having visited most of the locations of the festival, to be honest, the display at Cosmos Fukiage Gymnasium is the least impressive. In 2024 the dolls’ pyramid at Cosmos Arena is up from February 16th to March 9th.

Cherry Blossoms

The Somei Yoshino Cherry blossoms, the most common kind of cherry blossoms in Japan, typically bloom around the end of March. They are located along the footpath at the top of the embankment that overlooks the Arakawa floodplains. And as such, they are contrasted against the bright yellow canola flowers. They are still quite young, relatively speaking, so they are not that popular – yet!

Poppy and Corncockle Fields

Around the end of April, poppies and corn-cockles flowers start to grow at Cosmos Fukiage Arena. However, prime viewing for both is generally the middle of May. The corn-cockles at the Fukiage venue are advertised as “Nadeshiko” in Japanese. But nadeshiko flowers translates to “fringed pink” or Dianthus. However, it turns out the nadeshiko flowers at Cosmos Arena are actually “Mugi Nadeshiko” and people just call them “Nadeshiko” for short! Mugi Nadeshiko are corn-cockles.

In one field there are various shades of poppies including white and pink. There is also a field with orange poppies. In addition, there are a couple of fields of red poppies as well as a red poppy and nadeshiko mix. You can usually see carp streamers flying in the nadeshiko fields at Cosmos Arena. However, they have not been put up the last three years due to the pandemic. It remains to be seen if they will be put up in 2024.

I know its quite confusing, but this is not the main site of the “famous poppies” of Konosu. This is the smaller site and it is relatively far from the main site. It would take about an hour, maybe more, to walk between them. But despite being the “smaller” or “sub” site, the poppy fields at Cosmos Arena are very impressive. Furthermore, at this site you can see the flowers backdropped by the picturesque Arakawa Suikan bridge (water pipe bridge). Moreover, the vibrant stunning nadeshiko flowers are generally only grown at this site and not the main site.

Fukiage Poppy Festival

Fukiage Poppy Festival is just one part of the annual Konosu Flower Festival. As aforementioned, they are just one of two poppy fields in Konosu city. It is the smaller of two poppy fields. The other field, ‘Poppy Happy Square’ is the largest in all of Japan and has an eight day festival. At Fukiage, the festival is just on for two days. In 2024, that is Saturday May 18th and Sunday May 19th. After the festival is over, usually the week after, they allow you to pick the poppies for free.
