These were the countries Japan invaded. You will need to count it. The information comes from Wikipedia under the heading of World War 2.

British, Australian and Dutch forces, already drained of personnel and matériel by two years of war with Germany, and heavily committed in the Middle East, North Africa and elsewhere, were unable to provide much more than token resistance to the battle-hardened Japanese. The Allies suffered many disastrous defeats in the first six months of the war. Two major British warships, HMS Repulse and HMS Prince of Wales were sunk by a Japanese air attack off Malaya on December 10, 1941.

Thailand, with its territory already serving as a springboard for the Malayan campaign, surrendered within 24 hours of the Japanese invasion. The government of Thailand formally allied itself with Japan on December 21.

Hong Kong was attacked on December 8[25] and fell on December 25, 1941, with Canadian forces and the Royal Hong Kong Volunteers playing an important part in the defense. U.S. bases on Guam and Wake Island were lost at around the same time.

Following the January 1, 1942 Declaration by United Nations (the first official use of the term United Nations), the Allied governments appointed the British General Sir Archibald Wavell to the American-British-Dutch-Australian Command (ABDACOM), a supreme command for Allied forces in South East Asia. This gave Wavell nominal control of a huge force, albeit thinly-spread over an area from Burma to the Philippines to northern Australia. Other areas, including India, Hawaii and the rest of Australia remained under separate local commands. On January 15, Wavell moved to Bandung in Java to assume control of ABDA Command (ABDACOM). Japanese battleships Yamashiro, Fuso and Haruna (more distant).

In January, Japan invaded Burma, the Dutch East Indies, New Guinea, the Solomon Islands and captured Manila, Kuala Lumpur and Rabaul. After being driven out of Malaya, Allied forces in Singapore attempted to resist the Japanese during the Battle of Singapore but surrendered to the Japanese on February 15, 1942; about 130,000 Indian, British, Australian and Dutch personnel became prisoners of war.[26] The pace of conquest was rapid: Bali and Timor also fell in February. The rapid collapse of Allied resistance had left the "ABDA area" split in two. Wavell resigned from ABDACOM on February 25, handing control of the ABDA Area to local commanders and returning to the post of Commander-in-Chief, India.

Meanwhile, Japanese aircraft had all but eliminated Allied air power in South-East Asia and were making attacks on northern Australia, beginning with a psychologically devastating (but militarily insignificant) attack on the city of Darwin on February 19, which killed at least 243 people.

At the Battle of the Java Sea in late February and early March, the Japanese Navy inflicted a resounding defeat on the main ABDA naval force, under Admiral Karel Doorman. The Netherlands East Indies campaign subsequently ended with the surrender of Allied forces on Java.

In March and April, a raid into the Indian Ocean by a powerful Imperial Japanese Navy aircraft carrier force resulted in a wave of major air raids against Ceylon and the sinking of a British aircraft carrier, HMS Hermes as well as other Allied ships and driving the British fleet out of the Indian Ocean. This paved the way for a Japanese assault on Burma and India.

The British, under intense pressure, made a fighting retreat from Rangoon to the Indo-Burmese border. This cut the Burma Road which was the western Allies' supply line to the Chinese Nationalists. Cooperation between the Chinese Nationalists and the Communists had waned from its zenith at the Battle of Wuhan, and the relationship between the two had gone sour as both attempted to expand their area of operations in occupied territories. Most of the Nationalist guerrilla areas were eventually overtaken by the Communists. On the other hand, some Nationalist units were deployed to blockade the Communists and not the Japanese. Furthermore, many of the forces of the Chinese Nationalists were warlords allied to Chiang Kai-Shek, but not directly under his command. "Of the 1,200,000 troops under Chiang's control, only 650,000 were directly controlled by his generals, and another 550,000 controlled by warlords who claimed loyalty to his government; the strongest force was the Szechuan army of 320,000 men. The defeat of this army would do much to end Chiang's power."[27] The Japanese exploited this lack of unity to press ahead in their offenses.

Filipino and U.S. forces resisted in the Philippines until May 8, 1942, when more than 80,000 soldiers were ordered to surrender. By this time, General Douglas MacArthur, who had been appointed Supreme Allied Commander South West Pacific, had retreated to the safer confines of Australia. The U.S. Navy, under Admiral Chester Nimitz, had responsibility for the rest of the Pacific Ocean. This divided command had unfortunate consequences for the commerce war,[28] and consequently, the war itself.

Answer 2
