The lively East Asians were up 3-0 inside 12 minutes thanks to goals from Yuki Kanayama, Kenichiro Kogure and Yusuke Komiyama, setting the stage for the eventual rout to follow. An own goal from Yoshifumi Maeda in the 18th minute saw a glimmer of hope for the Oceania men, compounded by Ron Ginio's goal just a minute later which made it a tight 3-2.
It was a false dawn for the Solomons though, as Kenta Fujii made in it 4-3 in the 23rd minute and a pair of strikes from Nobuya Osodo and one more from Yusuke Inada ended the affair and brought yet another heavy defeat down on the deflated islanders in Brazil.
Japan now move into second place in Group A, tied on three points with Russia and Cuba. The Solomons, despite putting up some brave resistance in their games, are out of contention for a place in the next round.
