|Rugby union career|
Kensuke "Kenny" Iwabuchi (岩渕健輔 いわぶちけんすけ; born December 30, 1975 in Tokyo) is a Japanese rugby player and coach. He plays at stand off, and has 20 caps for the Japan national rugby union team. He also captained the Japan sevens team in the third sevens World Cup and was the first Japanese player to play professional rugby in England.
Very quick and good at initiating backline moves, Iwabuchi's Achilles heel at the top level was his kicking ability, which he himself acknowledged was inferior to that of his excellent contemporary Keiji Hirose, who was a very reliable kicker, both of conversions and in open play. (He was the backup to Hirose in the Rugby World Cup 1999.) Iwabuchi was also very unlucky with persistent serious injuries.
In 1998 he graduated from Aoyama Gakuin University in Tokyo, entered Kobe Steel and joined Kobelco Steelers. In October he proceeded to study overseas at Cambridge University where he won a Blue and much praise for his efforts in The Varsity Match.
In July 2000 he graduated from Cambridge and left Kobe Steel at the same time. In August he became the first Japanese player to join an English Premiership team when he signed up with Saracens in the Aviva Premiership.
In 2002 he suffered a severe knee injury playing sevens rugby at the Pusan Asian tournament.
