Meguro River Minna no Illumi
Osaki's annual Meguro River Minna no Illumi event has found a novel solution to the issue of massive energy consumption during Japan’s winter illuminations season. Resembling winter cherry blossoms, the pink LED used in the light-up are all powered by biodiesel electricity generated using waste oil collected from local homes and restaurants.
The eco-friendly lights illuminate a stretch of the 2.2km-long Meguro River near Osaki and Gotanda stations. You can catch this beautiful sight from 5pm to 10.30pm every day from December 5 2025 until January 31 2026.Check the event website for the event map and more details.
