A late Yuya Osako header handed Japan their first ever victory over Colombia in a 2-1 win.
An early penalty from Shinji Kagawa put the Asian side in front after Colombia’s Carlos Sanchez saw red for handball in third minute.
The South-American side then equalised through a Juan-Fernando Quintero free-kick just six minutes from half time.
Osako then won it for Japan in 73rd minute with a header from Keisuke Honda’s corner delivery.
The match opened with a bang when Japan had the first attack with David Ospina punching an effort out to Kagawa, whose effort found Carlos Sanchez’s hand in the box.
Referee, Damir Skomina dished out an instant red card for the former Aston Villa man and penalty for Japan.
Kagawa stepped up and calmly slotted it home past a diving David Ospina to put the Asian side in a shock early lead.
Colombia then struggled to break Japan down before Radamel Falcao was fouled by Mahoto Hasebe shortly before half-time.
Quintero stepped up to curl a shot under the wall’s legs and it squeezed into bottom right past Eiji Kawashima to level things up at the break.
Upon resumption of match, Japan came out as the more hungrier side with Osako going close in 54th minute.
The Werder Bremen striker picked up a cross from Kagawa but Ospina successfully deflected for a corner.
Japan eventually got their reward in 73rd minute from a Keisuke Honda corner when Osako headed home off the post to put his side back in front.
Colombia soon launched waves of attack but struggled to create clear cut chances with most shots either over bar or comfortably cleared.
In end, Japan held out for the win which is their first at a World Cup on European soil to top Group H, ahead of Poland vs Senegal later today.
