Ueno Zoological Gardens, one of Tokyo's major sightseeing spots, reopened Tuesday following nearly four months of shutdown due to the novel coronavirus.

The zoo will implement measures to reduce the risks of infection for the time being, including shortening its opening hours to 10 a.m. to 4 p.m. and limiting the number of visitors to 4,000 a day.

Visitors are also required to reserve in advance for a designated 15-minute time slot to enter the zoo, with it allowing in up to 200 people every 15 minutes.
