OH LA LA!!! We just learn that Tsukiji Fish Market is closed on Sunday morning (Obviously we haven't searched travel information in advance LOL). My Brother suggests to visit Shinjuku Gyoen National Garden. Viewing Cherry Blossom there is not in original schedule. A blessing in disguise, the garden is so big with many Cherry Blossom species, so beautiful. It has been crowded with sea of people. It is so warm to view Cherry Blossom with family on this beautiful day. We spend one morning here. I always love this Japanese activity in Spring, so romantic!!!
