Koshigaya Sun City Illumination

Koshigaya Sun City is a shopping center with a music hall in south Koshigaya. The main store is an Aeon and there are also several smaller shops. Each year Koshigaya Sun City have an illumination event in winter. It is actually one of the longest running winter illumination events in Saitama Prefecture.
They will switch on the lights and reveal the Christmas tree on Saturday November 11th 2023. The year before the pandemic began, the switch on event had become quite a large event. It was celebrated for the whole weekend with several different concurrent events including a food market. But since the pandemic its back to being a smaller event. In fact, in 2020, they didn’t even have a switch on event, but the illumination was up. This year, they will have a gospel choir and some live performances. They will also give up to 200 children, under the age of six, free candy. The event will start at 4 pm and the lights will be turned on at 5 pm.
The illumination will run until March 3rd 2024. The trees and the and bushes around the court yard, as well as the roofs of some stores have fairy lights on them. There is also a tunnel of light. In addition, the two meta sequoia trees, a symbol of Sun City, that are in front of Citizen’s Hall are lit up with fairy lights. They have a beautiful Christmas tree too, but that only stays up until Christmas night, December 25th 2023.
The illumination is turned on at 5 pm this year (it used to be 4.30) and is on until 10 pm. They haven’t specified the number of the lights they used this year, but in previous years it was about 70,000.
