Ajinomoto Stadium (味の素スタジアム, Ajinomoto Sutajiamu), also known as Tokyo Stadium in AFC Champions League, is a multi-purpose stadium in Chōfu, Tokyo, Japan. The stadium was founded at Kantō Mura, the redevelopment area formerly used by United States Forces Japan, in March 2001. It was the first stadium in Japan that offered its naming rights, which were sold to Ajinomoto Co., Inc. with a 5-year 1.2 billion yen (about 10 million U.S. dollars) contract, from March 2003 to February 2008. As a result, it was named Ajinomoto Stadium (味の素スタジアム, Ajinomoto Sutajiamu). This contract was renewed in November 2007 and extended by 6 years for 1.4 billion yen to February 2014, and in October 2013, the second renewal of the contract extended the term to February 2019.
