A 39-year-old man has been arrested for hurling a flare at the Chinese Consulate in the city of Fukuoka, police said.
No one was injured in the Tuesday night incident.
Kensaku Nakahara of Omuta, Fukuoka Prefecture, who said he is a company employee, was arrested at the scene for allegedly violating the minor offenses law. According to the police, he threw the flare into the consulate premises at around 11:05 p.m.
The incident is the second of its kind after a 20-year-old man was arrested Sunday for allegedly throwing a flare at the Chinese Consulate in Nagasaki.
Police said they were looking into the possibility Nakahara was motivated by the diplomatic row between Japan and China over the Senkaku Islands.
Nakahara reportedly arrived at the site by taxi and hurled the flare from outside the front gate immediately after getting out of the vehicle.
There were a few staff members working at the time.
On Sunday evening, a piece of burned paper was found at the consulate, and a suspicious man was seen fleeing on a motorbike, they said.
