Highlights: Wales 28-21 Japan

ByGareth GriffithsBBC Sport Wales

Captain Dewi Lake says Wales let themselves down during the lacklustre 28-21 Nations Championship victory against Japan in Cardiff.

Josh Adams added two tries to scores from prop Archie Griffin and wing Louis Rees-Zammit as Wales claimed a bonus-point win.

This was their second victory from four games in the competition but Lake was left frustrated with aspects of the performance.

"There were massive parts of that game where we let ourselves down," he said.
