In the pool A match against England, he played as centre due to Seiji Hirao playing as fly-half in the lineup. Three years later, Shinobu Aoki, who, like Matsuo, was part of the squad that won against Scotland in 1989, was his direct rival for the position as regular fly-half in the Japan national team after the Asia-Pacific qualifiers, but during the 1991 Rugby World Cup, Matsuo took Aoki's place as the regular fly-half for Japan. He took part at all the three pool matches of the World Cup first round, and contributed to the victory in the final pool match against Zimbabwe.
