I visited Kyoto three days ago and found a cherry tree in full bloom but other cherry threes are just in bud. We must wait one week at least for cherry blossom viewing and it is the best time for foreign tourists to come to Japan.
Many people all over japan go out to admire the cherry blossoms in full bloom. They spread mats on the ground under the blossoms and have parties with their family,friends or co-workers. Foreing tourists are welcome to join them.
