Some Mid-Season Women's Corporate Team Roster Changes


The Daiichi Life women's corporate team announced last week on its official site that Paris Olympics 10000 m runner Haruka Kokai and teammate Yuka Masubuchi left the organization as of July 31. Kokai was born in 2003. Kokai rose to the national level while at Sendai Ikuei H.S., winning the first leg at the National High School Ekiden her 2nd year to lead them to the overall national title. After graduating she joined Daiichi Life, then called Daiichi Seimei, in 2021. In March, 2023 she was the gold medalist in the women's 10000 m at the Asian Championships, and in December the same year she took 3rd in the National Championships 10000 m in an all-time Japanese #7 30:57.67 to score a place on the Paris Olympics team. In Paris she placed 19th.

In a statement released by Daiichi Life Kokai said, "I want to thank the team, who always put the athletes first as they shared this journey, and all my teammates for so many good times together. There were times I got really discouraged and almost forgot why I was doing this sport, but the people who stood by me and supported me gave me the courage to face my problems head-on without running away, and that helped me to take a new step forward."

Born in 2001, Masubuchi made the National High School Championships 2 years in a row while at Kinjo Gakuen H.S., taking 8th in the 3000 m her senior year, and ran the 1st leg at the National High School Ekiden 2 years straight. At Meijo University she made her debut at the National University Women's Ekiden as a 1st-year, winning her stage 3 years in a row and helping Meijo score back-to-back titles. She was named captain her senior year.

In a statement Masubuchi said, "2 years was too short a time with the team, but I'll always be grateful for the support of my teammates, the staff and others. I'll never forget that feeling, and I look forward to taking on the next stage of my career."

The Edion corporate team also announced that Kana Mizogami was parting ways with the team and leaving the company. Born in Kumamoto in 2004, Mizogami has focused on middle distance events since junior high school. Her 1st year of junior high she competed in the 800 m at the Junior Olympics, and she was 4th in the 1500 m there her 2nd year. At Luther Gakuin H.S. she excelled both on the track and in ekidens. Her senior year she was 5th in the 1500 m at the National High School Championships and 9th in the 3000 m.

The following February she represented Japan in the World Cross Country Championships U20 women's 6 km, where she was the top Japanese placer at 17th overall. After joining Edion she ran the 1500 m at the National Championships and won the Chugoku Corporate Championships 3000 m, but she has not raced since July, 2025.

At the same time, the Senko corporate team announced that Chika Kosakai and Azusa Koga have joined its roster. Senko was founded in 2021, first qualifying for the Queens Ekiden national corporate championships in 2023. Last year it finished only 24th in the Princess Ekiden qualifying race.

The 23-year-old Kosakai joined Japan Post after graduating from Narita H.S. in 2021, competing in the U20 National Championships and the Queens Ekiden. In 2023 she ran the 4th leg at the Queens Ekiden, helping Japan Post finish 2nd overall. But at the end of July this year, Japan Post announced that she had left the team.

Koga, formerly Mihara, was the same class year as Kosakai. At Ritsumeikan Uji H.S. she won her stage twice at the National High School Ekiden, and in 2020 she won both the 1500 m and 3000 m at the National High School Ekiden. In 2021 she joined Japan Post alongside Kosakai, but in August, 2023 she transferred to Route Inn Hotels. There she ran in both the Queens Ekiden and the National Cross Country Championships.

When I first read the news about Haruka Kokai I was surprised but perhaps the signs were there as she rarely appeared in the Daiichi Life social media accounts and photos. It would be a shame to see such a talent leave the sport entirely but I understand she had a lot of injuries in recent years. As a supporter, I'd love to see her re-start her career in another team or even go it solo (if at all possible).

Hokkaido Marathon Elite Field

The Hokkaido Marathon happens Aug. 30 in Sapporo. Although it's not a top-tier race on the global schedule, the JAAF gives it special status in qualification for the MGC Race Los Angeles Olympics marathon trials, with 3 spots available to men who run under 2:12:00 and women under 2:32:00. Compare that to the criteria for making the trials by running the WA platinum label Sydney Marathon the same day, where men have to run under 2:06:30 and women 2:23:30 regardless of how they place. It's hard to see that as anything other than disincentivizing Japanese runners from racing abroad, with protecting the JAAF's financial interest in domestic races being the priority over getting the best athletes into the Olympic trials. But anyway, there are pretty good fields of people willing to not step out of line. All 6 women with marathon finishes to their name have run under 2:30 in the last 3 years led by veteran Hitomi Niiya with a 2:21:50 in Tokyo 2 years ago. Most are in the 2:26-2...

Olympic Marathoner Nakamoto Scores 10000 m PB

http://www.sponichi.co.jp/sports/news/2012/05/19/kiji/K20120519003286760.html translated by Brett Larner London Olympics men's marathon team member Kentaro Nakamoto  (Team Yasukawa Denki) set a 10000 m PB May 19 at Sayagatani Field in Kita-Kyushu, finishing 9th at the Kyushu Corporate Track & Field Championships in 28:54.59.  "A PB makes me feel pretty good inside about things," Nakamoto commented with a smile.  "I'll be going into marathon training in good shape." Nakamoto's previous best time was 29:04.24.  In today's race he stuck to the back of the lead pack, saving his energy for a intended surge over the final stage but unable to execute as planned.  "My closing speed is still a problem," he said without seeming too concerned.  His coach Naoki Yamagashira  said, "We achieved our goal of improving his track speed.  He scored 100% today." Next up Nakamoto will run the Bupa London 10000 road race on April 27 as par...

Japan's Team for Nagoya Asian Games

The JOC announced the full lineups for the men's and women's teams for September's Nagoya Asian Games . Being hosted in Japan the Asian Games are a pretty big deal, and it's pretty close to the maximum of 2 athletes per event. The men's and women's triple jump, the women's 400 m and the women's discus throw only have 1 athlete on the Japanese team, and it's a big FU to the shot putters apparently as nobody was named to either the men's or women's teams even though people ranked lower in the World Athletics Asian rankings than top JPN shot putters Daichi Morishita and Chiharu Saka did make the team in other events. But, let's focus on what it is, not what it isn't. Going off this week's Asian rankings 8 men and 5 women are ranked #1 in their event, with a total of 19 men and 14 women ranked in the top 3. Factor in a limit of 2 per nationality and the relays and Japan's chances of scoring a great medal haul are looking good. M...
