Genki Omae scored twice and had a hand in the other two as Ryutsu Keizai University Kashiwa thrashed Fujieda Higashi of Shizuoka 4-0 to win their first national high school championship title on Monday.
A clever piece of skill from Omae set up Yuta Murase to lash home the opener after just six minutes at National Stadium and Omae nearly doubled the lead for the Chiba Prefecture school when he forced an acrobatic save from the Fujieda keeper Masashi Kimura on the stroke of halftime.
Omae made it 2-0 early in the second period when he beat Kimura at his near post with a superb volley and he put the game out of reach by smashing his second of the match and a tournament-leading seventh on 62 minutes.
Omae's goalscoring feat sealed an unprecedented treble crown of scoring titles at the inter-high school meet, the national youth championship and the national championship.
Taishi Taguchi completed the rout 19 minutes from time, lashing home following a flick on from a left-wing corner.
"We have played well today, maybe even too well," said RKU Kashiwa manager Yuichiro Honda. "It hasn't sunk in yet but I am looking forward to savoring this victory later on," he said.
