Tokyo / Shibuya

Ao no Dokutsu SHIBUYA (Blue Cave Illumination)

About 500,000 blue lights turn the zelkova trees from Koen-dori to Yoyogi Park into a glowing blue tunnel, with a new tree-shaped screen showing Christmas visuals. It is a 10-minute walk from Harajuku Station; entry may be paused when crowds get heavy, so weekday evenings are calmer.
