Tokyo's Shibuya is famed for its Scramble Crossing, where crowds of people criss-cross the intersection in a scene symbolising urban Japan’s congestion and anonymity. It may have added another boasting right.

Tokyu Railways' trains running through Shibuya and other stations were switched to power generated only by solar and other renewable sources starting April 1.
