Hoshikawa Illumination 2026
Last Updated on March 10, 2026

The city of Kumagaya in Saitama Prefecture is preparing to illuminate the Hoshikawa River area with a vibrant display of lights known as the Hoshikawa Illumination.
This annual event will see the central promenade transformed by thousands of LED bulbs, casting a seasonal glow over the water and surrounding walkways.
Local organizers aim to create a warm atmosphere for residents and visitors to enjoy during the colder months, highlighting the scenic beauty of the river that runs through the heart of the city.
The light installations are expected to include various themed displays and decorated trees along the banks, providing numerous opportunities for evening strolls and photography.
As a key part of the local winter calendar, the project involves community collaboration to enhance the visual appeal of the downtown district after sunset.
Spectators will be able to view the reflections of the sparkling lights on the surface of the Hoshikawa River, which serves as a central gathering point for the festivities.
The event is easily accessible for those traveling to the area, located within a short walking distance from the North Exit of Kumagaya Station.
Visitors are encouraged to explore the nearby shops and restaurants which remain active during the illumination period, adding to the lively spirit of the neighborhood.
