The 2005 World Exposition in Aichi Prefecture had to restrict admissions Sunday for the first time since the event started in March as crowds flocked in on the second day of a three-day weekend.
Monday is Respect for the Aged Day.
The number of visitors topped 280,000 by 7 p.m., the biggest turnout yet. The number exceeded the cutoff point of 170,000 and entrance restrictions were invoked starting at 12:50 p.m., according to the Japan Association for the 2005 World Exposition.
About 37,800 people had lined up by 8:25 a.m. when organizers opened the gates.
To get on the magnetically levitated Linimo train, a main transportation vehicle to the expo site, visitors had to wait as long as 75 minutes, while the 10,600 spots at six official parking lots were full by 9 a.m.
The expo wraps up its six-month run Sept. 25.
