The Asahi Shimbun Displays in Room 3 are a series of free temporary displays that showcase single or small groups of objects from the Museum’s collection, ranging from the earliest human artefacts to objects from the present day.
.....These displays are made possible by the support of The Asahi Shimbun Company, longstanding corporate sponsors of the British Museum. With a circulation of approximately 6 million for the morning edition alone, The Asahi Shimbun is the most prestigious newspaper in Japan. The company also publishes magazines and books, and provides a substantial information service via the internet. The Asahi Shimbun Company has a century-long tradition of philanthropic support, notably staging key exhibitions in Japan on art, culture and history from around the world.
