Owing to the 2015 Rugby World Cup and Japan's entry into the 2016 Super Rugby tournament, the format of 2015–16 Top League season was altered from the previous year. A pre-season competition with four pools was staged to provide each Top League team with five matches before the regular season started. The "Canon Eagles" in Pool D finished third with 1 draw and 2 losses, gaining 4 points and qualifying for 9th–12th place semifinals. At the end of pre-season the team reached 10th rank beating "Yamaha Jubilo" 27 – 24, but losing 25 – 48 against the "NTT Communications Shining Arcs".
