According to our tour guide, there are about 200 sakura varieties! Wow. Here are some of the photos of cherry blossoms I took in Tokyo. They look more varied than the ones I saw in in Osaka and Kyoto during the first week of April.
The last sakura bloom happens in the first half of May in the Sapporo (Hokkaido) area. To view the complete cherry blossom forecast, you can check out www.jnto.go.jp/sakura/eng/index.php.
