A group of South Korean lawmakers on Tuesday visited Dokdo prompting an immediate protest from Tokyo.

Seventeen members of the parliamentary National Defence Committee flew to the islets on military helicopters for a day-long visit, an aide to committee member Han Ki-ho said.

The trip ― described as a government inspection session ― was aimed at checking security measures around the islands which are guarded by the South’s coastguard, the aide told AFP.

A picture released by the committee showed the lawmakers shouting slogans with a placard reading “Dokdo is our land. We will defend it”.

Japanese Chief Cabinet Secretary Osamu Fujimura, who on Monday had urged the Seoul MPs to cancel their trip, said it was “extremely regrettable” that his call had gone unheeded. “We strongly protest it and we are urging South Korea to prevent future incidents,” Fujimura told a regular media briefing Tuesday in Tokyo.
