Japan held drill in November assuming foreign occupation of Senkakus islands

Tokyo [Japan], December 28 : Japanese forces conducted a drill at a remote southwestern island in November under the assumption that foreign forces had occupied the Senkaku islands--the Japanese-controlled group of islands claimed by China, according to several government sources.
The drill involving the Self-Defense Forces, Japan Coast Guard and police took place at an uninhabited island in Nagasaki Prefecture with land features resembling Uotsuri island. The island is one of the islets that make up the Senkakus in the East China Sea, Kyodo News reported.
Following the two-day drill from November 20 on Tsutara Island in Goto, Nagasaki Prefecture, the government had said the exercise was aimed at improving Japan's response to emergency situations in the country's island areas, and was "not intended for a specific island or a country."
China refers to these uninhabited islets as Diaoyu.
Tensions have escalated in the recent past between Japan and China over Senkaku island amid rising Chinese activities in waters surrounding the islands.
According to the sources, the exercise was aimed at improving the cooperation between organizations including the SDF and the coast guard to prepare for "grey zone" situations that stop short of full-fledged military attacks on Japan.
The government selected Tsutara to hold the drill because its coastal shape and its steep cliffs are similar to the characteristics of Uotsuri, the sources said.
Using helicopters and boats, the participants held landing drills and went over the roles and coordination of different entities, including a remote-island defense unit of the Ground Self-Defense Force, they said.
The 11th Regional Coast Guard Headquarters based in Naha, Okinawa Prefecture and the prefectural police's team tasked with guarding remote islands also joined the exercise.
