Cocoon City Night Illumination

Cocoon City Illumination 2023 ~ 2024 – This year the theme of the annual night illumination at Cocoon City is “Brilliant Promise”. Once again, they are increasing the number of lights used to make it the biggest illumination to date at the excellent mall in the heart of Saitama City.

Cocoon City Illumination

The Cocoon City illumination display just keeps on growing. From about 310,000 lights in 2020/21 to 370,000 lights in 2022/23 to 400,000 in 2022 / 23 to 450,0000 in 2023 / 2024. Their largest yet. There are a few other surprises too, outlined below. This year the lights are a champagne gold color. The illumination starts on Saturday November 11th and runs until Wednesday February 14th 2024. Their light up display always ends on Valentine’s Day annually. However, the Christmas elements, such as the ten meter tree, are always only available until Christmas day.

Cocoon City Night Illumination

Last year they added an eight light up display for the first time, but this year one of the ‘surprises’ is that they are adding two more. For a total of ten light display areas. This year the displays are at Cocoon Hiroba, Keyaki Walk, Hanamizuki Walk, Sakura Walk, Cocoon plaza, Kotsu Hiroba, Market Mall, Cocoon 1 Plaza entrance, Saitama Shintoshin east pedestrian deck and the east exit hiroba. Furthermore, there is even more illumination just a short walk away at Saitama Shintoshin aka Tamaari Town.

Christmas Tree

In addition, the Cocoon City illumination has a ten meter Christmas tree completely adorned with lights. It changes color to the music at intervals during the day. And they use projection mapping to light stars on the courtyard around the tree. However, the Christmas tree is taken down at the end of Christmas day.

Christmas Events

During the Christmas period they also have other events on, such as the very popular candle night. There is also a Christmas market. The Christmas events and illumination are seperate really, as the main illumination (excluding the Christmas tree) runs right until Valentine’s day. While the Christmas tree and Cocoon City Christmas events, such as the candle nights and workshops end on Christmas day. In addition, there are Christmas events at the neighboring Keyaki Hiroba (more information here). You can see specifics for Cocoon City Christmas (and New Year) here:
