D-day Wiki

The nation of Japan is still in development and is not available in the current release of D-day (v3.7).
They will be included as a fully playable side in the next release of D-day.

During the 1930's Japan launched a campaign of territorial expansion starting in 1931 with the invasion of the Chinese region of Manchuria and then with the Chinese mainland in 1937, this point is considered by many to be the beginning of World War II. Following the defeat of French forces in 1940 by the Germans the Japanese then also invaded the northern part of French Indochina (now Vietnam and Cambodia).

This aggression did not go unnoticed by the international community and Japan was placed under a oil embargo by America and Britain who demanded that Japanese troops withdrawal. With no indigenous source of oil and all oil imports blocked the Japanese only had enough reserves to last 2 years at most. Faced with this plans where made to invade the Dutch East Indies (now Indonesian) to secure a new source of oil, doing so would provoke a military conflict with America so it was also decided to launch a preemptive strike on American forces too.
This attack came on the 7th of December 1941 when three Japanese aircraft carriers launched strikes against the American naval based as Pearl Harbor bring the USA into World War II. On the same day attacks were launched against several other targets in the South Pacific including the Philippines and Hong Kong, with Dutch East Indies being invaded a few weeks later securing the new source of oil.

In the following months Japan launched attacks across Asia and the Pacific conquering the Philippines, Dutch East Indies, Thailand, Burma, Singapore, Guam, Solomon Islands, Gilbert Islands, Marshall Islands, Wake Islands and taking half of New Guinea. Japanese forces were poised to expand even further towards India, Australia and even America itself.

In June 1942 the Japanese launched an invasion of the American island of Midway in the North Pacific, American forces had cracked the Japanese communication cyphers though and was waiting in ambush for the Japanese naval force. The battle that ensued is regarded as one of the greatest naval battles in history and the destruction of the Japanese fleet marked a turning point in the Pacific War against the Japanese.
Following their defeat at Midway the Japanese were forced onto the defensive, over the next year they suffered multiple defeats resulting in the loss of the Solomon Islands, the Gilbert Islands and the Marshall Islands. Then with the loss of the island of Saipan in July 1944 the Japanese homeland was now within reach of American's new B-29 bomber.

As the war drew closer to the Japanese home islands preparations were made to resist the expected invasion and huge amounts of weapons where stockpiled for what would be expected to be the most bloody battle in all of human history.

That battle would not come thought because on August 6th the American Airforce dropped the first Atomic bomb on the city of Hiroshima completely obliterating it in seconds, then on August 9th a second Atomic bomb was dropped on the city of Nagasaki. Faced with this overwhelming devastation Japan was forced to surrender.
After Japan's defeat the country was occupied by the Americans who disarmed and banned all military forces in the country, only a limited police was allowed to remain.

With the outbreak of the Korean War in 1950 and the threat of the conflict expanding into a possible third World War. It was felt that the small American occupation force in Japan wouldn't be enough to defend against a possible attack, so it was decided to allow the Japanese to rearm.

Article 9 of the Japanese Constitution however disallowed Japan from have any military forces. To get around this law though the newly created armed force was named the Japanese Self Defense Force which was officially established in 1954.



When playing as Japan in the Post-War time frame there are two different sub-factions that you can choose from, Imperial Japan or the Japanese Self Defense Force (aka JSDF).

Choosing Imperial Japan lets you play using prototypes and paper projects designed in the closing stages of the War in a hypothetical continuation of the conflict past 1945.

Choosing the Japanese Self Defense Force lets you play using real life equipment designed during the 1950's and 1960's in a Cold War scenario.

You can choose which sub-faction you wish to play as in-game after your Mobile Construction Vehicle has been deployed into a Construction Yard. There will then be two options available in the sidebar, one for Imperial Japan and one for the JSDF. First click on the one you wish to play as, click on it again once it has finished building and then place it anywhere on the map to activate your choice. Once you have selected a sub-faction it is no longer possible to change it for the rest of the game.

Note: When the AI is playing as Japan it will always default to picking the Imperial Japanese sub-faction.
