Event Detail
The 55th All Japan Corporate Half Marathon Championships (第55回全日本実業団ハーフマラソン大会) is scheduled for Sunday, 14 February 2027, in Yamaguchi City, Japan. This is a national-level road-running competition for athletes representing Japan's corporate athletics teams, rather than a conventional mass-participation half marathon. The Japan Association of Athletics Federations (JAAF) lists the 2027 edition in its official competition calendar and identifies Ishin Me-Life Stadium, within Ishin Centennial Memorial Park, as the start and finish venue.
Race character and background
The event has more than half a century of history and is a fixture of Japan's highly competitive corporate-distance-running circuit. In the preceding 2026 edition, men and women raced a 21.0975 km half marathon from the stadium, alongside separate 10 km competitions. Only the half-marathon event and the 2027 venue/date have been confirmed from the 2027 calendar reviewed; the previous year's 10 km programme should not be assumed to recur without an updated race guide.
The stadium is a substantial athletics venue in the park west of central Yamaguchi. Previous editions used a road circuit returning to the stadium. The detailed 2027 route, elevation profile, checkpoint arrangements and start times have not yet been verified. Runners and spectators should consult the organisers' final course and traffic-management notices rather than relying on the previous year's map.
Eligibility and entry
This is principally an elite corporate-team championship. The 2026 competition featured invited athletes from established Japanese company teams, and entries were not structured like an ordinary recreational road race. 2027 qualification rules, eligible teams, individual entry arrangements, entry fees and registration deadlines remain to be confirmed. Prospective competitors should obtain instructions from their team or the championship organisers before making plans; recreational runners should not assume open public registration is available.
Getting to the venue
Ishin Me-Life Stadium is at 4-1-1 Ishin Koen, Yamaguchi City, in a large sports park. Yabara Station on the JR Yamaguchi Line is roughly a kilometre away on foot. Travellers using the Shinkansen can connect through Shin-Yamaguchi and onward by local rail or bus. Allow extra time for race-day access and any road closures.
The published 14 February 2027 date is confirmed, but the precise 2027 flag-off, bib distribution, athlete check-in, baggage arrangements, aid stations, prize schedule and finisher entitlements have not been verified. The date stored in ARC is a date-only midnight placeholder, not a published start time.
