Akuma invasion of Japan (2026)

The 2026 Akuma invasion of Japan was a major invasion of the western Japanese archipelago by Akuma forces. It resulted in the deaths of presumably millions of Japanese, as well as any refugees located in the invaded regions.

Initial invasion
In the previous years, the Akuma had been spreading quickly through Asia after the loss of India, Pakistan, Nepal, the Tibetan region all the way down to Laos and Cambodia. Sometime in early 2026, around February, the first Akuma presence in Japan quickly became a full-scale invasion after the creatures managed to cross the East China Sea.

Defence of Japan
As the Akuma are ruthless predators, countless lives were lost in the first weeks of battle. The JDEU is said to have defended their home with a ferocity so great, it had not been seen since the Battle of Moscow several years prior, which had previously taken the title of the bloodiest battle in the war. Although the Akuma had taken nearly all of Japan below Nagoya, the JDEU's constant fighting held the creatures off until May that year, which allowed the rest of the country to heavily fortify the border. Most notably, one of the last major cities to hold out, Ōsaka, was primarily defended by residents and civilian volunteers not properly enlisted by the JDEU; the battle of Ōsaka lasted a month and held back the Akuma insurgence surprisingly well.

Outcome
Practically all of Japan south of Nagoya was lost to the Akuma, but that allowed the military strongholds (especially Tokyo; see Tokyo nuclear deposit) to increase their defences tenfold. Millions of lives were lost, and it is currently estimated to be around 15 million, 3 million of which is believed to be foreign refugees. The invasion paved way for the Akuma to repeatedly attempt invading the coastlines, but most of these attempts failed as Akuma had not evolved to be marine creatures.
