Sunset street lights Seibeun

For years, the illumination display in Seibuen, an amusement park on the cusp of Tokyo, was Saitama’s largest illumination display. Furthermore, it was one of the largest in all of Kanto, aka the Greater Tokyo area. However, after they reopened further to renovations it is no longer the largest in Kanto, not even the largest in Saitama. It is a completely different illumination to before the renovations. But it is still the display that is on for the longest period of time in Saitama: this year it will be on for 124 days. This post also contains information for the cherry blossoms at the amusement park.

Seibuen Illumination Winter 2023 – 2024

For years, the illumination in Seibuen was called “White lantasia”. However, as aforementioned, it was a different type of illumination to display to what it is now. And what it is now is quite basic. In the winter of 2023/24 the light up event is called “Sunset Street Light Illumination”:

Last year, when they had the first illumination since the renovations and pandemic, Seibuen claimed that their illumination was ‘like nothing we’ve ever seen before’! It was an ambitious interactive illumination display, but it was very successful. In 2024, they make no such claim and it is quite a basic display.

They are using old fashioned amber filament light bulbs along the main street to create a romantic, nostalgic atmosphere. However, they will also use lasers, smoke and bubbles. Every 20 minutes (on the hour at 20 past and 20 to) they complement the illumination with a ten minute narration. And the lights dance to the “If you’re happy and you know it” song. Bubbles blow out of strategically placed bubble machines twice during the narration.

Amusement rides

Not all the rides operate at night. In fact its usually just the ‘Viking’ and ‘Octopus’ rides that are open after 6 pm. The rotating observation tower is also open. They light up the water feature in the ‘matsuri’ area and the lanterns there are turned on at night too.

There are approximately 500 cherry blossoms in Seibuen Amusement Park. Cherry blossom varieties at Seibuen include Somei Yoshino, Yoko (Sunlight) and Higanzakura. The view from the 80 meter high rotating observation deck is not to be missed! During the period of bloom, they light the sakura up at night.
