During World War II, Dimapur was the centre of action between British India and Imperial Japan. It was the staging post for the Allied offensive. The Japanese could reach Kohima where a siege was laid. Allied reinforcement came through Dimapur by rail and road for the push against the Japanese. An airport at Dimapur was also in use for supplies to the allied forces in Burma.The battle for Kohima about 77 km from Dimapur is considered the turning point for the Japanese retreat from South East Asia.
