"On July 31, 1999 GLAY held a concert called "GLAY EXPO 1999 SURVIVAL" at Makuhari Messe, gathering a total audience of 200 000 people making it the largest single concert to ever be held in Japan (this concert broke many records at its time, its numbers not including the many who were standing out of the Makuhari Messe observing the concert in the extreme summer heat). There was an incredible amount of publicity leading up to this concert, including having their faces printed on the sides of Japan Airlines jumbo jets. In 2001 and 2004 two more GLAY EXPOs were held. GLAY EXPO 2001 was divided into four separate performances at three different venues (Tokyo Stadium, Hokkaido, and Kitakyushu), and accumulated a total audience of over 280 000. GLAY EXPO 2004 celebrated their 10th anniversary, and was held in the parking lot of Universal Studios Japan selling out with 100 000 audience members in under 15 minutes."
