When we designed the holiday, the view was we would catch the cherry blossom. The season moves from west to east and is fickle time wise. The blossom only hangs on the trees for about a week, so we were to be pretty reliant on luck.
Given the choice, I think Kyoto would have been the prime place to see the cherry blossom, however on landing we found it had already moved to Tokyo. Yesterday it was too wet to take in a viewing and we did fear missing it all, so this morning we decided to risk the imminent rain and hit Shinjuku-goen, one of the top Tokyo day time spots. Fortunately it stayed dry until after we left.
