Fiji Men’s 7s team coach Gareth Baber says playing Japan in their home ground is always tough but the inclusion of the three Fijian players in the Japanese side will be an added challenge.
The Japan 7s team includes Jose Seru, Kameli Soejima and Lote Tuqiri.
Baber says they understand the first game is always a challenge but it will also be a good opportunity for them to put their game in place.
He adds they will not be complacent against Japan.
Fiji has two matches on the opening day of the Olympics 7s competition.
They will face Japan at 12pm next Monday before taking on Canada at 8pm.
Fiji will then play Great Britain at 12.30pm on the next day.
