Welcome to the National Museum of Nature and Science, known in Japanese as Kokuritsu Kagaku Hakubutsukan. You are standing in the northeast corner of Ueno Park, in Taito Ward, Tokyo. Locals often shorten the name to Kahaku, and you will hear that nickname in conversations around you. This is the only national museum in Japan devoted to the full sweep of natural history and the history of science and technology. Its founding purpose is to advance natural science and public education by researching, collecting, caring for and displaying specimens and materials. Interestingly, it is staffed by working researchers rather than the usual curators. The museum is made of two main buildings. The Japan Gallery, called Nihonkan, tells the story of the Japanese archipelago and the people living on it. The Global Gallery, called Chikyukan, follows the history of life on Earth and the story of humankind. Over the next few minutes I will take you through the museum's long history, its landmark building, and a few of the treasures that make it remarkable.
