I used to root for Team Japan way back 2012 but after Saori's departure the team seems deteriorating. I still have no faith in the present line up of Japan's NT. Unless they will have 6 footers they will probably make a podium. But with their present rosters, 5th to 6th place would be the best spot for them. Only Ishii has the potential to go against the Big 4 (China, Brazil, USA, Serbia). They should develop taller players. Only Italy and Russia could steal the spot from the Big 4 right now.
The Men's has huge hope with Nishida and Ishikawa uprising. But still their opponents are also upgrading USA, Russia, Poland and Brazil. But I am seeing a potential podium finish in the Olympics for Japan Men's with the homecourt advantage.
