Sakura time in Japan and specially in Tokyo is so pretty and most importantly the entire city is bright in pink and white cherry blossoms.
Every step every view be in built up Tokyo or park cherry trees are lined along the side walk or be office towers and where ever you look and go.
With Tokyo Tower visible in the distance, the cherry blossoms blooming on both banks of the water of Chidorigafuchi are illuminated more effectively by dusk hours.
