Great Britain's eventing team won gold after producing a dominant display in the showjumping finale at Tokyo Equestrian Park.
The trio of Oliver Townend, Laura Collett and Tom McEwen led by 17.9 penalties following their outstanding cross-country rounds on Sunday.
And they comfortably retained top spot, with McEwen going clear on Toledo De Kerser, Collett having four faults aboard London 52 and Townend also collecting four with Ballaghmor Class.
It is Great Britain's first Olympic team gold in eventing since Munich 1972, while Australia took silver and France bronze.
It is only Britain's third Olympic team crown in eventing after Stockholm in 1956 and Munich 16 years later.
Attention now switches to the individual final, which follows the team competition later on Monday, with Townend starting the showjumping phase in the silver medal position behind Germany's Julia Krajewski.
Reflecting on his round, McEwen said: "He is a class horse and a great jumper, so it was just up to me on top.
"My nerves were fine. They (Townend and Collett) are both brilliant riders, and I had no doubt they would pull it straight out of the bag quite easily and comfortably."
And Collett, who dropped places individually after having one fence down, added: "He (London 52) was his normal self at the start, then I think there was a reflection off the water and he just spooked, basically.
"He got it back together. It's a shame, but it could have been a whole lot worse in that situation. It was a very clever course."
