Craig Wing is set to become Japan's oldest ever RWC debutant after head coach Eddie Jones named his team for the match against USA at Kingsholm.
At 35 years and 289 days, Wing beats Shoji Ito, who was 34 years and 295 days when Japan played Scotland on 23 September. Wing was a late injury withdrawal from the matchday 23 in Japan's RWC 2015 opener against South Africa.
Jones has made four changes to the starting side that beat Samoa.
Hiroshi Yamashita replaces Kensuke Hatakeyama, who drops to the bench. Justin Ives takes over from Hitoshi Ono in the second-row. Male Sau is replaced by Wing in the centres, and Harumichi Tatekawa moves to outside centre to accommodate the switch. Yoshikazu Fujita comes in on the wing for Akihito Yamada, who drops out of the matchday 23.
Among the replacements, Shinya Makabe is the only change, as Ives moves into the starting XV.
The starting line-up contains 540 caps, Japan's third most experienced ever, with an average age of 29 years and 20 days.
