Jeev, who began the week with superb rounds of 68 and 70 and was as high as sixth, slipped to 22nd by the end after playing the final two rounds in 74 and 71 at the 7,191-yard Totsuka Country Club in Kanagawa Prefecture.
Meanwhile, Yuta Ikeda ended a 15-month winless run during which he came close many times.
He shot a three-under 69 for a four-day total of 17-under 271 and it gave him a three-stroke win from fellow-Japanese Taichi Teshima and Korean Hwang Jung-gon.
Ryo Ishikawa (73) was in tied fourth, six shots behind the winner.
It was Ikeda's 10th win on Japan Tour but the first since the Sun Chlorella Classic 15 months ago. He also won Canon Open once earlier in 2009.
This season Ikeda has posted nine top-10s this season, including three runner-up finishes in his last five starts.
