Japanese people in Shanghai have been warned their safety is at risk after four Japanese were attacked by several Chinese last week.
The warning comes in a newly issued notice from the Japanese consulate in Shanghai.
"They (the four Japanese) were first asked if they were Japanese by the five Chinese, and after confirming this were given a violent beating," said Isamu Ishikawa, chief of general affairs at the consulate.
"Since they didn't know the five Chinese, there is little possibility the attack was related to personal affairs," Ishikawa said.
The Japanese sustained minor injuries, and police are investigating the incident, Ishikawa told China Daily on Tuesday.
