HIROSHIMA - Visitors to the Hiroshima Peace Memorial Museum during Japan's Bon holiday period in August will be required to make reservations online, the facility said Friday, as it seeks to ease congestion.

The museum, which displays materials related to the 1945 U.S. atomic bombing of the western Japan city, will cap admissions at 1,000 people per hour from Aug. 8 to 16. Reservations can be made online from Friday.
