South Africa head coach Paul Treu heaped praise on his side after they beat New Zealand for the second time this season in a Cup final.
Having beaten Gordon Tietjens' side in the USA final in Las Vegas, this encounter was closer in a cold Tokyo as South Africa came from 12-0 behind to win 24-19 thanks to three tries and a penalty, a result which lifts them into second in the Series.
"It is unbelievable," said Treu.
"For us we have been so unlucky throughout the year, and to come back again after a disappointing tournament in Hong Kong, to bounce back and give a performance like that is great.
"It is not everyday you beat New Zealand twice in the final. It is good momentum going into the RWC Sevens in Moscow.
"Every win you have to take, and we can go back to South Africa as a happy team. For us we are going to enjoy this win tonight."
MORE REACTION ON DAY TWO
Alex Magleby, USA coach, Plate winners: "We had some close games, the guys were exhausted, our captain and our fast men are injured. But the guys kept working, they kept grinding and for us it important for us to learn how to do that. It is nice to get a trophy and get some points, and it will be a battle when we get to Glasgow."
Ben Ryan, England coach, Bowl winners: "It is good they learn from their errors. We controlled our first two games and I honesty think we should have beaten Australia on day one. We want to get onto our home patch, a few guys coming back from injury so we will finish hard. Dan Norton has been in electric form, top of the try charts, but he works the hardest too. That Rugby World Cup Sevens becomes even more important now."
Geraint John, Canada coach, Shield winners: "I think that is the big thing we spoke about when we unfortunately lost to Kenya this morning . Now we are in a battle and we have to fight and show some character which I think we showed in those last two matches. It is a bit of a battler going to Glasgow but I think we would prefer to be in our position than the other teams."
Jamie Henry, Japan Sevens: "For me it has been a roller coaster, going home for Dad's funeral, then flying back to be with the team. To play with them in front of a home crowd is something special and something I will cherish. The support has been tremendous but for me it is just for my Dad."
Stephen Gemmell, Scotland coach, on defeating Samoa: "That is as good as we have been. USA did their job against Fiji, we have to deal with ourselves. Massive disappointed against France with a golden opportunity but the boys have bounced back well."
Frankie Horne, SA captain after victory against Samoa: "That was a tough match, credit to Samoa they made us work very hard for it. Something special for us to come back from last weekend to this weekend. It is just amazing."
England's hat-trick hero Dan Norton: "The way we train, we want to be higher up, we want to be winning our games. It is always hard coming out in the second day knowing you have to play in the Bowl, but you have to do as well as you can, and we want to build some momentum ahead of the last two tournaments."
