Kasai Rinkai Park Sunflowers 2026: The Basics
"Flower and Light Movement" at Kasai Rinkai Park (葛西臨海公園) is a Tokyo Metropolitan Government project that builds large flower beds in metropolitan parks and stages seasonal flower-and-light displays. 2026 marks the project's 5th anniversary.
This year's theme at Kasai Rinkai Park is "Magic Hour: the time when life carries on". Just as the sky changes color at sunset, the lighting around the park shifts from orange to pink to purple.
Park entry, the sunflower field and the night light-up are all free. Tokyo Sea Life Park and the Ferris wheel charge separate fees.

25,000 Sunflowers: Varieties and Photo Spots
A sunflower field of about 3,800㎡ is planted on the lawn plaza next to the Ferris wheel, with about 25,000 sunflowers.
Two varieties are on show in 2026: Valentine and Haruka's Sunflower.
Valentine is a single-bloom variety in a soft creamy yellow, a gentle color that also works well in flower arrangements.
Haruka's Sunflower carries on the seeds of a sunflower that bloomed the year after the Great Hanshin-Awaji Earthquake, on the site of the home of Haruka Kato, a sixth-grader who died in the disaster.
By day you can see the yellow sunflower field against the blue sky and the Ferris wheel. In the evening, warm-toned lighting changes it into a different scene from daytime.
Inside the sunflower field there is also a "KASAI" sign photo spot decorated with fresh flowers.
Light-Up Hours and the Six Zones
The light-up runs every day of the event, from 18:00 to 23:00.
It is not just the sunflower field that gets lit: six zones stage different light displays, from the central promenade leading out of the station to the aquarium entrance and the area around Crystal View.
| Zone | Location and display |
|---|---|
| ① Fresh Sun | Central promenade by the fountain Sunset-like orange light and lighting that sparkles like water drops |
| ② Twinkle Light | Promenade in front of the service center A path lined with artificial sunflowers and round ball lights |
| ③ Blooming Garden | Sunflower field on the lawn plaza About 25,000 sunflowers under warm-toned lighting |
| ④ Evening Comes | Near Hotel Seaside Edogawa Tree lighting that shifts from orange to pale pink and purple |
| ⑤ Deep Sea Night | Tokyo Sea Life Park entrance Light evoking the water's surface and fish, plus a tuna-shaped lantern photo spot |
| ⑥ Dawn Glow | Central promenade in front of Crystal View Polyhedral objects whose light changes with your viewing angle |

To mark the project's 5th anniversary, collecting stamps at 3 of the 6 participating parks gets you an original tenugui (a Japanese hand towel), first come, first served.
Stamps are only available during each park's Flower and Light Movement period, and you need to install the stamp rally app "furari" on your smartphone to take part.
⚠️ At Kasai Rinkai Park you can only collect the stamp; the giveaway is not distributed there. You can receive it at the event sites in Koganei Park, Hibiya Park, Sayama Park and Kiba Park during their event periods.
Kasai Rinkai Park Sunflowers: FAQ
Q. Can I get there with the Tokyo Subway Ticket?
A. No. Kasai-Rinkai-Koen Station is on the JR Keiyo Line, so it is outside the coverage of the Tokyo Subway Ticket, which works on Tokyo Metro and Toei lines.
The Tokunai Pass, a one-day pass for JR local and rapid trains within Tokyo's 23 wards, does cover Kasai-Rinkai-Koen Station.

Q. Can I see the sunflowers during the day?
A. Yes. The sunflower field is open to see freely during the day. The night light-up starts at 18:00.
Q. What time should I arrive to see both the sunflowers and the light-up?
A. If you want the daytime sunflower field and the light-up in one visit, arriving between 17:00 and 17:30 works well.
If you only plan to see the night lighting, after 18:30 is better. For the limited menu, visit before the shops close at 16:30.
Q. Does the event still run if it rains?
A. The event or some of its services may be suspended or changed depending on weather emergencies or the power supply situation.
Check the latest notices on the official website and the official X and Instagram on the day of your visit.
At midday the yellow sunflower field spreads out under the Ferris wheel, and as the sun goes down the park's promenades and trees turn orange and purple. The biggest draw of this event is that the same place shows you a completely different summer scene depending on the hour.
From July 31 to August 16, 2026, fit Kasai Rinkai Park's sunflowers and magic hour into your Tokyo itinerary.
