One of the most famous spot for viewing cherry blossom in Okayama is the one kilometer long riverbank of Asahigawa (Asahai River) in the city. More than 200 cherry trees along the river creates a wonderful road for people and drivers. It is conveniently located near Okayama Castle and the famous Kōraku-en, one of the top three Japanese gardens in Japan. So you may visit all three sites at the same time!
By bus: around 10-12 minutes from Okayama Station to Kōraku-en.
On foot: around 25 minutes from Okayama Station.
The river is a C-shape and you may start from Okayama Castle and finish at Kōraku-en Garden. Enjoy!
