The annual three-day event — featuring more than 400 participants dressed as medieval samurai warriors fighting on horseback over flags that are shot overhead by fireworks — attracted more than 120,000 people, reports said. Yoshichika Hirata, a member of the festival's executive committee, told AFP that changing the date of next year's event to a cooler time of year would be discussed at a meeting on Thursday. "We sprinkled water on the track for the first time, as extreme heat was expected. We used three water-sprinkler cars, but it dried up quickly," Hirata said. One horse died during last year's festival, after which a majority of riders supported a plan to change the date, according to a survey conducted in December.
