Updates to Japan's Home Team at Aichi-Nagoya Asian Games


This week the JAAF announced changes to the lineup for its home team at next week's Aichi-Nagoya Asian Games. The main change announced was the withdrawal of Ririka Hironaka from the women's 10000 m, leaving only Nozomi Tanaka to do it as part of a 1500-5000-10000 triple. In theory it seems like it would be pretty easy and swap in an alternate, but apparently not. No announcement of withdrawals for Tomonori Yamaguchi, who missed June's National Championships 5000 m with injury, or high jumper Ryoichi Akamatsu, who hasn't competed since early last October and made the Asian Games team based his 8th-place finish over a year ago at the Tokyo World Championships.

Yes, it's disappointing that there's no replacement for Ririka, especially in one of Japan's stronger events.

Tomonori Yamaguchi ran 7:47 for 3000 in Germany 2 weeks ago so he seems fine. Towa Uzawa withdrew from the 200 and was replaced by Akira Hayashi (Keio University).

Waseda Leads Top 7 Teams Under Izumo Ekiden CR, Ivy League Best-Ever 3rd

3rd last year, Waseda University  scored its first Izumo Ekiden win since 2010, taking almost 2 minutes off the CR and leading the top 7 teams under the old record of 2:07:51 for the complete 6-stage, 45.1 km course. Waseda was 16 seconds back in 7th after the First Stage, but its 2nd runner Ojiro Honda  made that up easily and put them 6 seconds out front. A massive 22:56 CR for the 8.5 km Third Stage by Shadrack Kipkemei  (Nihon Univ.) dropped Waseda back to 2nd even though its runner Ryuki Suzuki  broke the old CR too, but back-to-back CR on the next 2 stages by 1st-year  Haruki Niizuma  and Shunpei Yamaguchi  put anchor Shinsaku Kudo  out of reach of the rest of the field. Kudo duly won the 10.2 km anchor stage in 29:00, bypassing a 2:06 time entirely for a new 2:05:56 CR, just under 2:48/km average pace for the complete course. Defending champ Koku Gakuin University  struggled a bit in the first half of the race but came on strong in th...

April's Kasumigaura Marathon Canceled

The organizing committee of the 31st Kasumigaura Marathon and International Blind Marathon has been working hard to develop safety and health protocols adequate to mitigate the risk of spreading the coronavirus at the event. But with increased case numbers in recent months and a number of prefectures remaining under an extended state of emergency declaration, the future outlook for the organizers' ability to hold the race safely remains uncertain. As a result, the decision has been made to cancel this year's race, originally scheduled for Apr. 18. The popular Kasumigaura Walking event held in tandem with the marathon has also been canceled due to the pandemic situation. We thank you for your understanding.  Translator's note: The Kasumigaura Marathon had 10,096 finishers in its last running in 2019. Its cancelation follows those of March's Tokushima Marathon and April's Nagano Marathon  earlier this week. The only major spring Japanese marathons still on the calen...

2026 Izumo Ekiden Preview

We're at the Ironman World Championships in Kona, Hawaii where JRN associate editor Mika Tokairin is making her debut here as an athlete after having come to Kona for years as a journalist. Next to Kona the most eyes worldwide will be on the Chicago Marathon , where a solid Japanese contingent is lining up including men's marathon NR holder Suguru Osako and half marathon NR holder Tomoki Ota , Kiyoshi Koga , and the other power couple in Japanese marathoning, last year's Berlin Marathon runner-up Akira Akasaki and Paris Olympics 6th-placer Yuka Akasaki . Osako's manager told JRN that he is going for the Asian Record of 2:04:43 held by Moroccan-born Bahraini El-Hassan El-Abbassi who was served up a 4-year suspension not long after setting the record. Last year's Warsaw Marathon winner Ryoma Takeuchi is at the Perth Running Festival marathon in Australia where he hopes to add a CR win to his PB at July's Gold Coast Marathon. On the home front Keita Satoh i...
