Winter illuminations around Christmas and New Year have become a popular attraction in cities across Japan. Illuminations are typically displayed between November and December, but some run longer, starting as early as October and running until Valentine's Day or even into spring.

Illumination Structure: Light from the LEDs around the periphery of the flat light diffusion plate is scattered and reflected within the plate to create diffused light that illuminates from directly overhead. This light is equipped with diffuser by default.
