Chris Packham, Michaela Strachan and James Wong join the lively cherry blossom celebrations taking place across Japan this spring. The blossom, or sakura, is one of the world's most stunning seasonal wonders, with blankets of pink flowers sweeping across the country. Whilst James looks at the history of this famous festival, Chris and Michaela discover the wildlife that live alongside the blossom. And all three find themselves partying with the crowds of Japanese 'blossom watchers'.
