Technically, a duchy is the territory ruled by a duke or duchess. I decided on "duchy" because it is essentially the same system that supports Prince Edward:

Since the 14th century the [Duchy of Cornwall's] main purpose has been to provide an income, independent of the Monarch, for the heir apparent. That income covers the cost of the public and private life of the current Duke, The Prince of Wales. Neither he nor his sons receive an allowance from the Civil List. When there is no male heir, the Duchy reverts to the Monarch, and its income to the Exchequer.

The tax system described here follows the same logic as that of the hamlet (chapter 25). In a hamlet, nine allotments are farmed by eight families, with the ninth being assessed as tax. Similarly, there are nine provinces in a kingdom, with one (the capital province), being partitioned (enfoeffed) and taxed to support the imperial civil service. And within each province, the capital district is partitioned and taxed to support the provincial civil service.

During the Tokugawa Era, chief constables were known as Oometsuke (大目付). They remain the favorite subject of period crime dramas such as Dora Heita, in which the inspector infiltrates a corrupt town and ferrets out the wrongdoers, usually resulting in a climactic sword fight at the end and the revelation of the inspector's true identity.
