Hakone Champ AGU's 4th Runner Kyosuke Hiramatsu Reveals He Suffers from Rare Disorder

 

On Jan. 8 Aoyama Gakuin University held a victory celebration at the school's Aoyama Campus in Shibuya, Tokyo for its win at the 102nd Hakone Ekiden, the 9th win for AGU in the last 12 years and its second threepeat. AGU's 4th runner at Hakone, Kyosuke Hiramatsu (3rd yr.) took 3rd on his leg and set up Day One anchor Asahi Kuroda (4th yr.) to run down the leader on the uphill Fifth Stage and take the Day One win. At the celebration he revealed that he had been suffering from a rare disorder, acquired idiopathic generalized anhidrosis.

This disorder, which the Ministry of Health, Labor and Welfare estimates to afflict only 100 to 200 people nationwide, primarily men aged 10 to 30, impairs the function of sweat glands throughout the body. As a result those affected have difficulty regulating body temperature and are highly susceptible to heatstroke. The cause is unknown and no established treatment exists, but according to the National Intractable Disease Information Center in about half of the known cases patients show improvement through steroid pulse therapy, which involves IV injection of corticosteroids.

Hiramatsu ran the half marathon for AGU at the important Kanto Region University Track and Field Championships his 1st and 2nd years but was a DNF his 2nd year. His 3rd year he was among the leaders until near the end of the race, when he suddenly slowed and finished 27th. He had other races where he dropped out as well. Head coach Susumu Hara suspected that Hiramatsu was suffering some kind of illness and had him undergo detailed testing, which revealed the anhidrosis problem.

In July Hiramatsu was admitted to a hospital to start undergoing treatment. "It was hot the day I got out of the hospital," he said. "The minute I stepped outside I started sweating and my shirt got soaked." He continues to undergo regular blood testing and check-ups to monitor his condition. "I owe it all to Coach Hara for suspecting I was sick," he said.

On Feb. 1 Hiramatsu will run the Beppu-Oita Mainichi Marathon along with Kuroda. "I'm targeting sub-2:10," he said. He and the other 3rd-years have never lost at Hakone since entering Aoyama Gakuin. In his 4th season Hiramatsu is expected to be one of the team leaders in its quest for a 4th-straight title. "I have no intention of letting someone else take the Fourth Stage," he said.

Multiple National Records This Weekend

Olympic and World champion Haruka Kitaguchi got the biggest headlines among Japanese athletes this weekend, overcoming a rough last year and a half that included injury and a coaching change to break her own javelin throw NR by over a meter and a half to win the inaugural WA Ultimate Championship in Budapest. U20 WR and Asian AR holder Ziyi Yan opened with a big 68.05, 0.67 m further than Kitaguchi's best-ever from back in 2023. That could have been the end, but Kitaguchi came back from a 61.15 m first attempt to throw a massive 68.92 m NR on her next one, ultimately enough for the win. She still has a long way to go to match the 18-year-old Yan's 71.74 m from May, but it was a clear statement that Kitaguchi is back. Back home at the National Corporate Track and Field Championships in Kyoto, women's pole vault NR holder Misaki Morota continued a solid comeback season of her own, bettering her NR from May by 1 cm with a 4.51 m on her first attempt. Morota took another 3...

On the Loss of the ARRS Database

At some point in the last few months I discovered that both versions of the ARRS database, the static one and the searchable version , are gone. Last week David Monti posted a link to the ARRS history of an event he covered in Race Results Weekly, I guess copying and pasting a link from last year without looking at it, and that reminded me to write something about the loss of the database. The Association of Road Racing Statisticians was basically a one-man show operated from the remote Northern California shores by Ken Young . When the site existed its intro read: The Association of Road Racing Statisticians (ARRS) is an independent, non-profit organization that collects, analyses and publishes results and statistics regarding elite distance running at distances 3000m and longer...The data of ARRS is stored in the ARRS database, which has more than 1.3 million performances from more than 240,000 races by more than 95,000 elite and sub-elite distance runners worldwide...This website ...

Keita Satoh Running New Balance Fifth Avenue Mile

1500 m U20 NR holder Keita Satoh (Nike Swoosh TC) is running this weekend's New Balance Fifth Avenue Mile , the first time that a Japanese man has been invited in the race's 45-year history. In university Sato had to change focus away from middle distance to the half marathon-scale lengths of the Hakone Ekiden stages, but since graduating in March and relocating to Flagstaff he has refocused on the 1500 m, going from 3:43.19 in April in his first 1500 m in almost 4 years to 3:38.30 over the course of 5 races. Fifth Avenue will be his last race before heading back to Japan for one more track 1500 m and some down time. Men's entries with best 1500 m times in last 3 years: Stefan Nillessen (NED) - 3:29.23 (2025) Flavien Szot (FRA) - 3:30.74 (2025) Oliver Hoare (AUS) - 3:31.07 (2024) Jake Heyward (GBR) - 3:31.18 (2026) Titouan Le Grix (FRA) - 3:31.46 (2026) Romain Mornet (FRA) - 3:31.62 (2025) Adam Spencer (AUS) - 3:31.83 (2026) Pieter Sisk (BEL) - 3:31.85 (2025) Gary Martin (...
