Ground Province

The Ground Province is the largest, most populous, and most economically powerful province in The Book of Five Rings. Military presence here is more diluted compared to the Water, Wind, and maybe Fire Province. Government officials from this province or its subordinate prefectures often use the economic clout of this province when negotiating with government officials from other jurisdictions.

The Premier Shogun for the Ground Province tends to be either army officers or business moguls.

The Ground Province consists of six prefectures:

Highlands Prefecture

The Highlands Prefecture is, predictably, mostly highland. It was home to the earliest known settlers of the Book of Five Rings. Now, it has become a mostly rural place populated by several prominent monasteries, making this a more religious part of the country. There is a mix of Buddhist, Taoist, and Shinto temples, although there are also historic sites of the old religions, i.e. nameless animistic religions that the earliest Five Rings settlers practiced before Buddhism, Taoism, or Shintoism was introduced to the country.

Brick Prefecture

Although the major industries of The Book of Five Rings are currently information technology, retail, and book publishing industries, it does have its fair share of heavier industries, which are mostly focused in this prefecture. The Mortar Academy, where most of the shoguns and high-ranking military officers often graduated from, is located here. This prefecture and the Mortar Academy are frequently referred to collectively as "Brick and Mortar".

Roof Prefecture

The largest city in the Book of Five Rings, Shinshyuu, is located in this prefecture. Understandably, it is also home to the largest university, financial district, and many others of the most metropolitan or cosmopolitan elements of the country.

Desert Prefecture

This prefecture has some small oil reserves, the operation of which have been quite profitable, relative to their scope of operation. Otherwise, it is mostly desert.

Tundra Prefecture

Frontier Prefecture
