Local hope Kenichi Kuboya took out the Japan Open as the Australian contingent failed to make an impact on Sunday. Kuboya secured his sixth Japan Golf Tour title with a one-under 70 for a four-round total of eight-over 292 at the challenging Naha Golf Club in Okinawa. Filipino Juvic Pagunsan (75) grabbed second place, one stroke behind the winner, while overnight leader Tetsuji Hiratsuka of Japan could only manage a frustrating 78 and slipped to third at 10 over. China&aposs Ashun Wu (70), South Korean Kim Do-Hoon (73) and Japan&aposs Yusaku Miyazato (77) finished in a tie for fourth at 12 over. Brad Kennedy (76), who had a share of the lead after an opening-round 72, was the best-placed Australian in equal 38th at 21 over. Steven Conran (76) was a further shot adrift in a tie for 43rd, while fellow Aussie and former winner Paul Sheehan (78) was equal 54th at 27 over.
