India was not occupied by Japan during World War II.

During World War II, Japan occupied numerous countries and regions across East Asia and the Pacific. However, among the options you provided, India was not occupied by Japan during the war.

To understand this, we can look at historical records and the course of events during World War II. India was under British colonial rule at the time, and Japan's primary objective in Asia was to establish its "Greater East Asia Co-Prosperity Sphere." While Japan conducted military campaigns in Southeast Asia and the Pacific, India was not directly invaded or occupied.

It is important to note that there were some Japanese military advances towards India's northeastern region, such as the Battle of Imphal and Battle of Kohima in 1944, as part of the Burma Campaign. However, these attempts were ultimately thwarted by Allied forces, and Japan did not gain control over any significant part of the Indian territory.

Thus, India remained outside of Japan's occupation during World War II.
