Cherry blossoms viewing at Shinjuko Gyoen

Hi Cherry, it's so wonderful you'll see the Cherry blossoms, its a wonderful time to visit Japan.
In Tokyo, its more optimal to see the Sakura from March 29 to April 4. Since we are having a little bit of a warmer winter, the Sakura will blossom on time.

But since Shinjuko Gyoen is such an amazing place to see cherry blossoms, I am sure that you'll be able to see the alte bloomers and the othersakura, although not in full bloom.

The earlier you go, the better.

I hope you enjoy your stay!
