This edition: Japan: Islands of Extremes
First aired: December 27, 2016.
Japan’s 7,000 islands stretch for over 2,400km, and cover an incredible range of climates. Winter in the central and northern islands can be savage, but summer in the sweltering southern islands couldn’t be more different. Armies of crabs patrol steamy mangroves, while on sub-tropical beaches, macaques prove the depth of their intelligence and adaptability by washing sandy food before they eat it.
