Ep.1:
Dan covers the Japanese period of isolation, the Meiji restoration, and the early imperial era up up to the battle of Shanghai in the second sino-japanese war. Common themes are the unique japanese cultural intensity, extreme nationalism, extreme anti-communism, and the japanese constitution which placed the military not under the elected government, but the emperor.
Ep.2
The Rape of Nanking. Everyone in the world is horrified, from Nazis to Americans. America applies extensive economic sanctions to Japan, and increases them for each major aggressive act Japan takes. Starved of the raw materials needed to finish their war in China, Japan decides to attack Pearl Harbor.
Ep. 3
Japan invades the entire Pacific. Japan destroys a British fleet a few days after Pearl Harbor. The Japanese seize Malaysia from the British, giving them their worst defeat in their entire history. The Japanese invade the Philippines and destroy the American-Filipino army at Bataan, but the Japanese realize the Americans aren't that easy to conquer. The Bataan death march occurs.
Ep. 4
America sets up internment camps for Americans of Japanese descent. The Doolittle raid occurs. Japan begins planning the battle of Midway in response. The battle of the Coral Sea occurs. Midway happens soon after, with the Japanese fleet destroyed. Douglas Macarthur is a prima donna and Ernest King is an asshole. Different strategies for the pacific war are proposed by them. King preempts Macarthur with the invasion of Tulagi and Guadalcanal. The Japanese commit atrocities in the Pacific theater.
Ep. 5
Australia defends New Guinea from the Japanese. Cannibalism becomes a major problem there. The campaign in the islands around Guadalcanal continues. The Americans adopt the island hopping strategy. Yamamoto is killed. Tarawa is invaded by America. Images of the battle are shown to the American public. The invasion of Saipan occurs, along with the battle of the Philippine sea, aka the great marianas turkey shoot. Afterwards, Saipan earns the name of suicide island after the Japanese suicide attack, and the mass suicide of the remaining soldiers and civilians.
It is now July of 1944. The Japanese garrisons in the Pacific are starving. The Japanese fleet is decimated. Japanese air power is both underperforming and out of date. Mass death continues unabated in China. And now American heavy bombers are in range of the home islands.
