Cherry Blossoms

At this time, only the northern part of Japan such as Aomori, Hokkaido, etc will have cherry blossoms. Places like Hakodate, Hirosaki, Kakunodate, Kitakami, Sapporo and such you'll still be able to see well.

But in Tokyo, and Kyoto the season is already over. Maybe some late bloomers here and there like In Shinjuku Gyoen and Hamarikyu Garden:

But mostly all became leaves already.
