Japan is divided into 47 prefectures, which rank immediately below the national government and form the country's first level of jurisdiction and administrative division. They include 43 prefectures proper, two urban prefectures, one regional prefecture and one metropolis. In 1868, the Meiji Fuhanken sanchisei administration created the first prefectures to replace the urban and rural administrators in the parts of the country previously controlled directly by the shogunate and a few territories of rebels/shogunate loyalists who had not submitted to the new government such as Aizu/Wakamatsu. In 1871, all remaining feudal domains (han) were also transformed into prefectures, so that prefectures subdivided the whole country. In several waves of territorial consolidation, today's 47 prefectures were formed by the turn of the century. In many instances, these are contiguous with the ancient ritsuryō provinces of Japan.
A city is a local administrative unit in Japan. Cities are ranked on the same level as towns and villages, with the difference that they are not a component of districts. Like other contemporary administrative units, they are defined by the Local Autonomy Law of 1947.
In Japan, a district is composed of one or more rural municipalities within a prefecture. Districts have no governing function, and are only used for geographic or statistical purposes such as mailing addresses. Cities are not part of districts.
A city designated by government ordinance, also known as a designated city or government ordinance city, is a Japanese city that has a population greater than 500,000 and has been designated as such by order of the Cabinet of Japan under Article 252, Section 19, of the Local Autonomy Law.
The Japanese addressing system is used to identify a specific location in Japan.
