Kawasaki Frontale hammered Ventforet Kofu 4-0 to remain top of the J. League second stage on Saturday, extending their unbeaten run to 16 matches.
Yoshito Okubo headed home a minute to the break before an own goal and strikes from Yu Kobayashi and Elsinho in the second half saw Kawasaki, which dominated throughout, ease to a comfortable three points at their Todoroki Stadium.
"We knew we'd be attacking for a long period of time and should have scored more," said Okubo, who scored his J. League record-extending 170th goal.
