ao no dokutsu

From Shibuya's Hachi-ko (Park with statue of Hachi the dog), just follow the blue lights to Yoyogi Park.

There you will find the Ao no Dokutsu (Blue Cave).

If only smartphones had a way to control long shutterspeed...

Still it was nice to see.

This event runs from November 30 to December 31.
