France broke out of a 13-13 halftime deadlock, scoring four second-half tries Saturday to beat Japan 42-23 in the first of two rugby tests.
Japan started well and might have been on the way to another giant-killing performance when they matched the Six Nations champions through a tough first half.
But winger Damian Penaud scored two tries, one in each half, to help lift France to their ninth consecutive victory, their best post-war winning streak.
The match was played in hot conditions at the Tokyo Stadium in Nagoya and France, coming off a heavy test program, used their fitness to outlast a Japan team whose recent international play has been limited by the Covid-19 pandemic.
Flyhalf Matthieu Jalibert was instrumental in France's improved second-half showing. He helped to set up at least two tries and put the French team into good field position. Jalibert recently has been sidelined with a leg injury but made an impressive return and France improved consistently as the match went on.
