JAAF Unable to Confirm Results of SRY Testing of Its Female Athletes

On Aug. 26 the JAAF announced that although it has complied with World Athletics' mandate for genetic testing of female athletes competing in next month's Tokyo World Athletics Championships, it is not in a position to know the testing results of individual athletes.

On July 24 World Athletics had announced that in order for athletes to compete in women's events at the Tokyo World Championships they must undergo testing by Sept. 1 to check for the presence of the SRY gene on the Y chromosome, a determining factor in the development of male biological characteristics. Results of the testing are communicated to the athletes themselves and are not sent to the JAAF.

The lineup of the women's national team for the Tokyo World Championships will only be announced after confirmation that athletes have both met the entry requirements and undergone testing, creating concerns that some athletes may later be found to be ineligible after having already been named to the team.

At a press conference on the 26th JAAF executive Hiromichi Tasaki commented, "The diversity of physical sexes has been made clear from a medical point of view, and it is our position that this should be protected." The JAAF's official opinion is that the terms "men's" and "women's" should be understood to refer to "category titles established to facilitate the convenience of competition."

Regarding the merits of genetic testing of athletes Tasaki said, "It is an issue that requires careful discussion and judgment from a range of perspectives. Athletes who wish to participate will be made to understand in advance both that the test is a necessity and that risks may arise as a result of the testing. If athletes wish to be tested, we will provide a system under which they can undergo the testing with the highest degree of consideration for them."

Depending on the results of the test athletes may have the opportunity for a re-test, but if they are found ineligible to compete in the women's category, Tasaki said, "they may suffer social difficulties and psychological distress. This is highly sensitive personal information, and if it were to become known by others it could result in serious issues for the athletes."

Athletes can choose to abstain from testing from a human rights perspective, but in that case they will in principle be ineligible to compete in the Tokyo World Championships. For that reason the JAAF is seeking to work closely with World Athletics to obtain the necessary information and provide support and counseling to any affected athletes.

The two articles I compiled here seem to raise a lot of questions left unaddressed.

Rui Aoki and Shunsuke Kuwata Making U.S. Debut at United Airlines NYC Half

When the National University Half Marathon was canceled in 2011 after the massive earthquake and tsunami struck northeastern Japan 2 days before the race, JRN talked to the New York Road Runners about bringing 2 collegiate runners to the United Airlines NYC Half Marathon the next weekend as a show of support. It wasn't possible to pull it together in the immediate aftermath of the disasters, but a year later we brought 2 young 2nd-years from Hakone Ekiden CR breaker Toyo University , Kento Otsu and Yuta Shitara , who had been the top 2 Japanese collegiate finishers at the Ageo City Half Marathon in November before Hakone. Shitara ran 1:01:48, at the time the fastest-ever by a Japanese man on U.S. soil, with Otsu running a solid 1:03:15. Thanks to that great start the Ageo-NYC partnership became a regular thing, and except for the pandemic it's continued every year since, expanding this year to June's New York Mini 10 km when 2 runners from Mt. Fuji Women's Ekiden runne...

Chepkirui Over Sato Again to Win 2nd-Straight Nagoya Women's Marathon, Chen Breaks Malaysian NR (updated)

This year's Nagoya Women's Marathon felt like a changing of the guard, with some the bigger domestic names over the last few years fading early and a lot of newer faces stepping up with quality debuts or second marathons. The front group was set to be paced for 2:20 flat with the 2nd group at 2:23:30 to hit the auto-qualifying time for the 2027 MGC Race, Japan's L.A. Olympics marathon trials race in Nagoya. Up front things went out OK, but after a 33:10 split at 10 km Ayuko Suzuki , 2:21:22 here 2 years ago, lost touch, ultimately finishing 23rd in 2:33:28. Windy conditions started to play with pacers' ability to keep things steady and the pace slowed majorly over the next 10 km, but even with a 34:05 second 10 km there were big-name casualties. 2024 Nagoya winner Yuka Ando was next to drop, ending up 17th in 2:30:32. NR holder Honami Maeda was next, followed quickly by Bahraini Kenyan Eunice Chumba and debuting Wakana Kabasawa . Maeda faded to 21st in 2:31:21, whil...

How it Happened

Ancient History I went to Wesleyan University, where the legend of four-time Boston Marathon champ and Wes alum Bill Rodgers hung heavy over the cross-country team. Inspired by Koichi Morishita and Young-Cho Hwang’s duel at the 1992 Barcelona Olympics I ran my first marathon in 1993, qualifying for Boston ’94 where Bill was kind enough to sign a star-struck 20-year-old me’s bib number at the expo. Three years later I moved to Japan for grad school, and through a long string of coincidences I came across a teenaged kid named Yuki Kawauchi down at my neighborhood track. I never imagined he’d become what he is, but right from the start there was just something different about him. After his 2:08:37 breakthrough at the 2011 Tokyo Marathon he called me up and asked me to help him get into races abroad. He’d finished 3rd on the brutal downhill Sixth Stage at the Hakone Ekiden, and given how he’d run the hills in the last 6 km at Tokyo ’11 I thought he’d do well at Boston or New York. “I...
