TOKYO - Prime Minister Sanae Takaichi has come under online criticism after a music-backed video of her visit to an area of southwestern Japan hit by a deadly earthquake was labeled a "PR piece" by some social media users.

The video, set to piano music and recapping Takaichi's Monday visit to Kumamoto Prefecture, where a magnitude-7.1 earthquake struck on July 28, shows her flying over disaster-hit areas in a helicopter, meeting residents and inspecting an evacuation center.
