Asian Junior Record Holder Osako Leads Japanese Contingent at Boston Marathon

by Brett Larner

Through two long-standing race partnerships, a group of sub-elite Japanese runners will again be part of this year's Boston Marathon field.  In the women's race, two-time Katsuta Marathon winner Kana Kurosawa (Team Hitachi) returns to Boston after running a PB 2:43:03 to win this year's Katsuta.  Making her marathon debut alongside Kurosawa is Ome 30 km Road Race winner Ami Utsunomiya (Canon AC Kyushu), with a 1:13:39 half marathon best at Feburary's Marugame Half Marathon.

On the men's side, Katsuta winner Hiroki Kai (Team Raffine) and 3rd-placer Kaito Iwasa (Chuo Univ.) will be running, Kai in his third marathon of the year following his Katsuta title in January and 2:18:07 PB in Tokyo in February. Earning his spot in Boston with a 5th-place finish in Ome and coached by two-time Boston winner Toshihiko Seko, Hiroki Sugawa (DeNA RC), will also line up in his second career marathon after debuting in 2:24:14 at the 2014 Gold Coast Airport Marathon in Australia.

Like Utsunomiya, half marathon Asian junior record holder Suguru Osako (Nike Oregon Project) will be making his marathon debut in Boston.  Osako ran his 1:01:47 Asian Jr. record in winning the 2010 Ageo City Half Marathon, afterward avoiding the distance in favor of the track until this year when he shaved his PB down to 1:01:13 in Marugame in February and won March's Portland Shamrock Run in an easy 1:04:12.  If he clears Futoshi Shinohara's 2:14:10 from 1990 Osako will break into the all-time Japanese top ten on the Boston course.

Women
Kana Kurosawa (Hitachi) - 2:43:03 (Katsuta Marathon 2017)
Ami Utsunomiya (Canon AC Kyushu) - debut - 1:13:39 (Marugame Half 2017)

Men
Hiroki Kai (Raffine) - 2:18:17 (Tokyo Marathon 2017)
Hiroki Sugawa (DeNA RC) - 2:24:14 (Gold Coast Airport Marathon 2014)
Kaito Iwasa (Chuo Univ.) - 2:25:17 (Katsuta Marathon 2017)
Suguru Osako (Nike Oregon Project) - debut - 1:01:13 (Marugame Half 2017)

Ichiyama and Kirui Lead Marugame Half Elite Field

Last year's winners Betsy Saina and Edward Waweru, both of Kenya, return to the Feb. 3 Kagawa Marugame International Half Marathon, but in both cases they have tough competition. Ranked #1 in the women's race is Mao Ichiyama (Wacoal) with a 1:09:14, 3 seconds better than Saina's winning time last year. 3 seconds slower is Sinead Diver (Australia) with a 1:09:20 on home ground last year. Sara Hall (U.S.A.) isn't far behind, and with track star Ayuko Suzuki (Japan Post) making her debut off a brilliant run at last weekend's National Women's Ekiden it should be a solid pack up front.

In the men's race, 2017 marathon world champion Geoffrey Kirui (Kenya) leads the way, his best recent time a 1:00:04 in New Delhi two years ago. Only 2 seconds behind is Shadrack Kiplagat (Kenya), with Evans Cheruiyot (Kenya) and the Japan-based Waweru just over 20 seconds back. Waweru's condition is a question mark after an injury at the New Year Ekiden. Kenta Murayama (Asah…

Mokgobu and Sonoda Return to Beppu-Oita Mainichi Marathon

After an exciting head-to-head last year that saw them race each other to sub-2:10 PBs, Desmond Mokgobu (South Africa) and Hayato Sonoda (Kurosaki Harima) return to the Feb. 3 Beppu-Oita Mainichi Marathon. The pair face not only each other but recent sub-2:10 men Hicham Laqouahi (Morocco), Abdela Godana (Ethiopia), Hiroyuki Yamamoto (Konica Minolta), Daisuke Uekado (Japan/Otsuka Seiyaku), Justus Kiprotich (Kenya), Takuya Fukatsu (Asahi Kasei) Kohei Ogino (Japan/Fujitsu) and Yihunilign Adane (Ethiopia) and sub-62 half marathoners Keijiro Mogi (Asahi Kasei), Charles Ndirangu (JFE Steel) and Shuho Dairokuno (Asahi Kasei), setting up a better-than-average pack by Beppu-Oita standards.

For the Japanese men Beppu-Oita counts toward qualification for the MGC Race, Japan's 2020 Olympic Trials. Sonoda and Uekado have already made it along with fellow entrants Naoki Okamoto (Chugoku Denryoku) and Tomohiro Tanigawa (Konica Minolta), but for Ogino and others it will be just about their last …
