if I had such info/links, rest assured I'd share them here.
as I don't, I'm asking here.
Ah well, thanks.
I would have to guess though that a realistic map would have to be based on Japan winning a negotiated end to the war as it was in OTL or Japan doing things differently in 1941 such as taking the chance that their move into the East Indies wouldn't necessarily get the US involved and hence no need to attack American possessions.
In the former scenario, I would conservatively guess we would seem something like this:
Japanese-governed
Empire of Japan
-Japanese Home Islands including the Ryuku Islands, Southern Sakhalin, and the Kuril Islands, as well as Korea.
Kwantung Leased Territory
-Southern part of the Liaodong Peninsula.
Government-General of Formosa
-Formosa (Taiwan), Hong Kong, Macau (to be purchased from Portugal), the Paracel Islands, Hainan Island (to be purchased from the Chinese puppet regime).
South Seas Government Office
-Guam, Nauru, Ocean Island, the Gilbert Islands and Wake. And probably the Mandate territory including the Marianas, Carolines and Marshall Islands.
Melanesian Region Government-General or South Pacific Government-General
-British New Guinea, Australian New Guinea, the Admiralties, New Britain, New Ireland, the Solomon Islands, the Santa Cruz Archipelago, the Ellice Islands, and maybe the Fiji Islands, the New Hebrides, New Caledonia, the Loyalty Islands, and the Chesterfield Islands.
East Indies Government-General?
-Singapore, Dutch East Indies (minus Java), British Borneo, Labuan, Sarawak, Brunei, the Cocos and Christmas Islands, the Andaman and Nicobar Islands, and Portuguese Timor (to be purchased).
Siberia Government-General?
-(former?) USSR up to the dividing line with Germans? Depending on how the war ends. Could be that Germany and the USSR end up negotiating a peace somehow and then Japan gets to kickstart negotiations on ending the war in the Pacific through the USSR as an intermediary? In that case there may not be any involvement in the USSR.
Japanese-puppetized States
Manchukuo
-Chinese Manchuria.
Mengjiang
-Inner Mongolia territories west of Manchuria and maybe Outer Mongolia
Republic of China
-maybe if Japan approaches Chiang suspecting he's more concerned about the communists than the Japanese and say "let's make a deal...".
Republic of the Philippines
-the Philippines
East Indies Kingdom/Kingdom of Java
-Java (the Japanese seemed to foster Indonesian nationalism more on Java and less on the other islands, so maybe they would create a puppet Java state based on the promise that in the future Java would form the basis of an Indonesia state from Japan's East Indies holdings (and maybe through unification with Mahamalaya)?)
Kingdom of Burma
-Burma proper (minus the parts annexed to Thailand).
Kingdom of Thailand
-Pre-war Thailand, also expanded with portions of British Malaya, Burma, and French Indochina during the war.
Kingdom of Mahamalaya
-Remainder of the Malay states plus Sumatra.
Kingdom of Cambodia
-Cambodia.
Empire of Vietnam
-Annam, Cochinchina and Tongking.
Kingdom of Laos
-Laos
I suggest the book Supercontinent for further info.
Thanks. What's the name of the author though?
