Ajinomoto Stadium

Ajinomoto Stadium, formerly known as Tokyo Stadium in the AFC Champions League and rugby competitions, 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 sold its naming rights, which went to Ajinomoto Co., Inc. on a five-year, 1.2 billion yen contract from March 2003 to February 2008 to name it Ajinomoto Stadium. This contract was renewed in November 2007 and extended by six years for 1.4 billion yen to February 2014; in October 2013, the second renewal extended the term to February 2019.
