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.
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.
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.
[2] In 2002 he suffered a severe knee injury playing sevens rugby at the Pusan Asian tournament.
