Hanami - Cherry Blossom Viewing

Hanami literally means "flower viewing", however, it commonly refers only to cherry blossom viewing.

As you can see, late March is the predicted opening (ie.  "kaika (開花)" when a cherry tree has its first open buds)  and during the first ten days of April, the cherry blossoms should be in full bloom ("mankai (満開)" is the Japanese term for "full bloom")  in Osaka and Kyoto.
