A long-shot sweep of the top three spots paid out 13,000,390 yen on a 100 yen wager at a local horse race Friday, the highest return in the history of legal gambling in sports in Japan. The return for the 1-2-3 winning combination in the 14-horse field on the dirt track at Oi Racecourse in Tokyo beat the previous record return of 10,149,930 yen set at Fukushima on April 9.
