The Blues opened the scoring in the 8th minute on a clear action concluded by a decisive overflow from Stade Toulousain winger Matthis Lebel.
An advantage quickly canceled by the Japanese reply and a try from Yamanaka at the conclusion of a dazzling recovery (12th).
The Japanese full-back then netted twice, giving Japan a 15-7 lead at halftime.
On an individual feat, the substitute scrum half of the Blues, Baptiste Couilloud, ended up offering victory to the XV of France, 20-15, which ended the season with ten victories in as many matches.
