Matsuo Breaks High School Half Marathon Record in 1:02:47


At the 48th Kanagawa Half Marathon at Yokohama's Nissin Olio Group's Isogo Plant, Jinya Ozaki (Teikyo Univ.) outran tough competition from National University Ekiden champion Komazawa University and Hakone Ekiden winner Aoyama Gakuin University to take 1st in the men's race in 1:02:04. AGU's Sho Fukutomi was 2nd in 1:02:07, with Komazawa's Rinta Muta 3rd in 1:02:08. High schooler Nichika Maeda (Miura Gakuen H.S.) took the women's race in 1:16:30.

But it was another high schooler who made headlines. 3rd-year Koki Matsuo (Shiritsu Funabashi H.S.) ran 1:02:47, taking 28 seconds off the fastest half marathon time ever run by a Japanese-born high school student. Last summer Matsuo ran the 5000 m at the National High School Track and Field Championships, and in November he went under 14 minutes for 5000 m, his time of 13:55.07 putting him into the top class of high school running.

At last fall's Chiba Prefectural High School Ekiden Matsuo set a new CR of 24:06 to win the 8.0875 km Fourth Stage. At December's National High School Ekiden he was assigned the most competitive stage, the 10.0 km opening leg, where he ran an excellent 28:54 for 4th to demonstrate his abilities on the road.

At the Kanagawa Half Matsuo went out in the lead group of collegiate runners, hitting 10 km in 29:33. He faded in the 2nd half but managed to hang to finish 17th overall in 1:02:47, cracking the 3:00/km barrier to better the 1:03:15 record set by Yuta Minamisaka (Kurashiki H.S.) in 2023.

The high school girls' half marathon record also nearly went down, but at a different race. At Ibaraki's Moriya Half Marathon, Anna Szbrucek (Ushiku H.S.) debuted in 1:13:33, just short of the 1:12:06 record set in 2017 by Yuka Kato (Toki Shogyo H.S.). Born in Japan to Slovakian and Bulgarian parents, Szbrucek holds the 2000 mSC and 3000 mSC high school records.

The men's race in Moriya was a group run by Chuo Gakuin University, Kota Yoneda leading his team in 1:04:15. CGU runners took 9 of the top 10 spots, with only Sota Takeichi (Ryutsu Keizai Univ.) breaking up the party in 1:04:58 for 9th.

Great stuff by Matsuo though we know not to raise too much expectations after we saw how college careers are different and some talents don't fully bloom (see Yoshioka and Ishida). Great potential there though.

What is scary is the depth that once again AGU shows with depth runners running low 62s and with a few those of being first years too.
Encouraging for Komazawa as well since Muta is a debuting first year and Niitani will be there too next year. Chuo having a couple of guys in the mix too though I don't know what year they are.

Oh well, ekiden season won't come fast enough.

Sorry to have been silent for a while. JRN associate editor Mika Tokairin  was in Taiwan for Ironman Penghu, where she won her age group to qualify for Kona for the first time. Right after that we moved for the first time in 14 years, and immediately after that I headed to the U.S. to help Keita Sato  get settled in his new training base in Flagstaff.

Everything You Need to Know About the 2026 Hakone Ekiden

The Hakone Ekiden is the world's biggest road race, 2 days of road relay action with Japan's 20 best university teams racing 10 half marathon-scale legs from central Tokyo to the mountains east of Mount Fuji and back. The level just keeps going higher and higher , hitting the point this year where there are teams with 10-runner averages of 13:33.10 for 5000 m, 27:55.98 for 10000 m, and 1:01:20 for the half marathon. It's never been better, and with great weather in the forecast it's safe to say this could be one of the best races in Hakone's 102-year history, especially on Day One. If you've seen it then you know NTV's live broadcast is the best sports broadcast in the world, with the pre-race show kicking off at 7:00 a.m. Japan time on the 2nd and 3rd and the race starting at 8:00 a.m. sharp. If you've got a VPN you should be able to watch it on TVer starting at 7:50 a.m. on the 2nd , and again at 7:50 a.m. on the 3rd . There's even a 2-hour high...
