Mondo Duplantis broke the pole vault world record for the 14th time on Monday, clearing 6.30m to secure his third world title.
The American-born Swede had already clinched the gold medal, but pushed on to break the world record of 6.29m he had set in Budapest in August.
He failed in his first two attempts with the bar set at 6.30m, but it was third time lucky for the 25-year-old.
It was a jump which reaffirmed Duplantis’ position as a modern great of the sport, extending his winning run to eight consecutive gold medals at both indoor and outdoor events.
The other events of the day had long since finished, and, despite the time approaching 11pm in Tokyo, the stands at the Japan National Stadium remained packed as Duplantis’ supporters stayed behind to watch him make history again.
Speaking afterwards, Duplantis thanked them for sticking around.
"It’s better than I could have imagined,” the two-time Olympic gold medalist told reporters. “To give you guys this world record is amazing. The crowd were so loud. Thank you so much. I’m just so happy."
The silver medal fell to Emmanouil Karalis of Greece after he cleared 6,00m, while Australia’s Kurtis Marschall completed the podium after matching his personal best of 5.95m.
The women’s pole vault will be decided on Wednesday, but no Britons will compete after Molly Caudery was forced to withdraw through injury.
She hurt her ankle while warming up ahead of qualifying.
Writing later on Instagram, she described herself as “heartbroken,” adding that she was awaiting a formal diagnosis on the extent of the injury.
