Lord Foster said: "It is a great honour to receive this award and to join such august and illustrious company, which includes so many esteemed colleagues and friends.
"I am particularly delighted to receive this honour because I feel such a great affinity with Japanese art and architecture.
"The time I have spent working in Japan has provided some of the richest experiences of my life. I accept this award with tremendous pride."
Born in Manchester in 1935 and brought up in the run-down Levenshulme district, Lord Foster attended Manchester University School of Architecture and City Planning, before studying for an MA at Yale, in the United States.
