The South Korean carrier said the suspension would last until the end of April while it checks "safety measures related to the Hiroshima route, airport facilities, planes and training," Agence France-Presse reported.
The flight from Incheon, near Seoul, was carrying 73 passengers and eight crew when it smashed into the localizer — a large gate-like structure, six meters high, that sits around 300 meters from the start of the runway.
Nobody was killed, but 27 people were injured.
Transport officials from Japan and South Korea were investigating the accident, amid suggestions that a sudden down draft may have played a part in the crash, the AFP report said.
The accident brought memories of an Asiana flight that crashed in San Francisco in July 2013, killing three people and leaving 182 injured.
