In the Strike Witches universe, the Empire of Fuso (扶桑皇国 ? fusou koukoku) is an island-country placed at the eastern tip of the Eurasian continent. In a sense, it is analogous to the Empire of Great Japan.
Though there is no direct portrayal of this, one can infer by the term "empire" that the head of state is the Emperor, who seems to be revered by the people. Its national insignia appears to be a slightly altered Rising Sun, and the national emblem is the sakura.
Its history differs from real-life Japan from the point that, after the country's unification in the 16th Century, it did not implement national isolation policies during the Azuchi period. Rather, it assertively advanced into overseas markets, growing early into a maritime trade power.
Also during the Azuchi period, it discovered a new island in the Pacific Ocean. Because it was larger than the Fuso mainland, had abundant underground resources and was mostly an uninhabited region, this island was transformed into an overseas territory under the name of South Seas Island (南洋島 nan'you-shima). Thanks to an influential daimyo immigrating to here in the early 17th Century, it developed into an important supplier of resources for present-day Fuso.
Since it was necessary for foreign trade, it developed the technology to process raw materials into high-grade ones and is currently mass-producing/developing small-sized, great-added value, high-credibility industrial goods. It monopolizes foreign trade from the Pacific to the Indian Ocean and has a reputation as a maritime, industrialized power that rivals with Britannia, and is second only to Liberon. During the 17th Century, it fell into a state of war with Britannia due deploying mercenaries in the Netherlands. As it puts emphasis on maritime defense, it has a strong navy and possesses a great number of witches-use aircraft carriers.
Other than the Fuso Sea Incident, it has remained relatively untouched by the Neuroi incursions. However, Fuso remains a nation at the forefront of Striker development falling just behind Liberon in this area.
Another piece of territory under Fuso's control and ownership is Urajio: located on the Russian mainland and the region consisting of real life Vladivostok. Urajio is a busy port city with merchants, traders, a vast market and serving as a stop along a major supply line and trade route across "The Empty Desert Region" to send supplies to support the Orussian Front-lines and in all possible likelihood to other Eastern allied nations. Being a a very busy, bustling port city region and the importance of it's supply and trade routes; Urajio serves as a hub for trade for a large amount of goods and services for sale; ranging from soft drinks, movie theaters, and even striker parts. Urajio was given to Fuso in history as a likely gift, though the exact details as to the exact circumstances and context for this is not yet outlined.

- Other than an alternative name for Japan, "Fuso" is also the name of something like a world tree that appears in in Chinese mythology. Legend goes that it existed somewhere in the middle of the eastern sea and would produce a new sun every morning. This story seems to be the source of Japan's name as the "Land of the Rising Sun".
- The South Seas Island is based on an old legend about a lost continent that once existed somewhere in the Polynesia.
