Japan is an archipelago of more than 6,800 islands situated off the eastern coast of the Asian landmass. Its diversity of climate types and habitats support a wide variety of wildlife. Japan's culture is a rich blend of Asian traditions and more modern Western influences. It is governed by a democratically elected parliament but also has the world's oldest hereditary monarchy. Japan is one of the most economically powerful nations in the world. Its industries have produced goods that have shaped the lifestyles of people in many countries. However, the rapid pace of industrialization and the pressures of a fast-growing population have resulted in pollution and overcrowding which, together with an ageing population, present Japan with challenges for the future.
