Kenyan Benson Kipruto set a new course record in the men's Tokyo Marathon on Sunday, finishing in 2 hours, 2 minutes and 16 seconds.
He broke the previous record held by former world record holder Eliud Kipchoge in perfect racing conditions on the streets of the Japanese capital.
In the women's race, Ethiopia's Sutume Asefa Kebede finished first, clocking 2:15:55. She beat Kenya's defending champion, Rosemary Wanjiru and also set a new women's course record from Shinjuku to the Imperial Palace.
Kipruto outpaced Timothy Kiplagat in the final kilometers to win the Tokyo title, finishing 39 seconds ahead of his compatriot. This victory adds to his wins in Boston in 2021 and Chicago in 2022.
With this performance, the 32-year-old Kipruto improved his personal best by almost two minutes and now ranks as the fifth-fastest marathon runner of all time in events approved by World Athletics.
"I am so happy to get the course record," Kipruto told reporters.
"I think I'm ready for the Paris Olympics, I would be happy to represent my country in Paris, but that relies on my country for selection. I'm still waiting on that, but I'm ready."
Kiplagat had to be convinced not to pull out of the race by his coach after the death of his training partner, marathon world record holder Kelvin Kiptum, in a road accident last month.
Vincent Kipkemoi Ngetich finished third in 2:04:18 to give Kenya a podium sweep, with Ethiopians Hailemaryam Kiros and Tsegaye Getachew in fourth and fifth places.
Kipchoge was struggling at halfway with the pace under the course record time of 2:02:40 he had set in 2022, and the double Olympic champion had slipped two minutes behind the leaders by the 30-kilometer (18.64-mile) mark. He finished 10th.
Kebede and Wanjiru had been in the leading group throughout the women's race, but at the 37km mark, the Ethiopian upped her pace to pull clear of her rivals and claim her first major marathon title by 19 seconds.
Her time bettered Brigid Kosgei's 2022 women's course record of 2:16:02 and took more than two minutes off her previous personal best time of 2:18:12.
"I'm truly happy," the 29-year-old said. "It was a very tactical race. Everything went well, and the result was better than I expected.
"I ran a good time in a major race, and I hope the Ethiopian Athletics Federation will select me for the Paris Olympics. I would like to win (gold) and break the Olympic record."
Kebede's compatriot Amane Beriso was third in 2:16:58, more than a minute clear of Dutch Olympic long-distance track champion Sifan Hassan in fourth place.
Ichitaka Yamashita was the fastest Japanese man in a time of 2:06:31 to finish ninth, while Hitomi Niiya took the local honors in the women's race with a sixth-placed finish in 2:21:50.
