Germany have been World Champions four times no less, but they've come to Qatar with a point to prove after finishing bottom of their group in Russia four years ago.
Japan are no pushover, eight of their squad play in the German Bundesliga, and two in the Premier League.
But the first half went the way of the European powerhouse.
Just after the half hour mark, Germany were awarded a penalty when David Raum was brought down by the Japanese keeper.
Man City's Ilkay Gundogan put the spot-kick down the middle to give his side the lead.
And in the second half, Japan came back.
With 75 minutes gone, Manuel Neuer spilled it and Ritsu Doan, just on as a substitute, had an easy finish.
Then with seven minutes of normal time to go, a long ball over the top beat the German defense.
It was controlled inside the box by Takuma Asano and buried into the roof of the net to give Japan a shock lead.
Japan held on to a deserved and first win ever over Germany.
Germany are now under real pressure to qualify for the next round. Next up, they face Spain on Sunday.
