Tokyo joy for Blitzbokke
South Africa have secured the Tokyo Sevens title after beating New Zealand 24-19 in a thrilling final at the Prince Chichibu Memorial Ground on Sunday.
In a repeat of the USA Sevens Cup final, which South Africa also won, the result now moves Paul Treu's side onto 100 Series points, 32 behind New Zealand but two ahead of Fiji in second.
At the other end of the table, Scotland and USA are now joint twelfth with 46 points apiece ahead of the eighth round in Glasgow, after the USA beat Scotland in the Plate final.
In the Cup semi-finals, New Zealand beat last year's champions Australia 35-17 while Treu's side held on to beat France 14-12 with Australia finishing third. England won the Bowl and Canada the Shield in the other finals on day two.
Earlier, USA's Luke Hume brought an enthralling Plate semi-final to a close with a dramatic last-minute try, with the decisive conversion being kicked by Shalom Suniula to win 21-19.
Scotland beat Samoa, 21-17 with Colin Gregor, the man to have played in every minute of every match this season with the decisive try.
England recorded a second victory over Argentina at the 2013 Tokyo Sevens to lift a second successive Bowl title and eight points to their Series tally. Dan Norton scored twice to take his tournament tally to 10 as Ben Ryan's side won 38-0.
Norton earlier scored a second successive hat-trick and Christian Lewis-Pratt kicked a decisive conversion as England dramatically beat Wales 21-19 while Argentina booked their place after Valentin Cruz made a last-minute try-saving tackle to prevent Kenya overturning a 12-10 deficit.
Earlier, Agustin Migliore scored the opening try of day two as Los Pumas beat Canada 7-5. Norton scored his first hat-trick against Portugal to book England's place in the semi. Last week's finalists Wales narrowly beat the hosts 22-14.
Canada came from 7-0 behind to beat hosts Japan to lift the Shield and claim three vital Series points. Having lost to the hosts 14-10 on day one, Geraint John's side were able to reverse the result on day two with Sean Duke crossing for four tries.
Six different players scored for Canada as they beat Spain 38-0 to reach the Shield final. Katsuyuki scored a dramatic try for the hosts Japan to book their place in the final after beating Portugal 19-15.
