Wildlife cinematographer Nobuaki Hirano is on a one-year quest documenting the four seasons in Tokyo's Okutama. In summer, he guides us through the mountains in search of a mysterious tree that "glitters" during the day. On the way, we witness an astonishing scene: the young of an endangered species of bird getting down like a professional dancer, but for reasons that leave us chuckling! From the clear running streams to the hillsides, Hirano's lens captures nature in all its glory.
