From 1942 to 1945, the island was occupied by the Japanese. The Government House became the residence of the Japanese admiral also for three years (from March 1942 to October 1945). It was during this period that Subhash Chandra Bose, who took the help of Japanese in his fight against the British, stayed at the Island for a day in December 1943. Netaji also hoisted the national tricolor at the top of the Government House. The Japanese too left their imprint on the island which stand in the form of bunkers used as watch points to safeguard the Island from any foreign invasion.
