city of Japan
Let an agent explain the city as a category of Japanese municipality, distinguish grades such as core and designated cities, relay criteria and counts from official sources, and distinguish Japanese cities from towns, villages and the special wards of Tokyo.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the city as a category of Japanese municipality, distinguish grades such as core and designated cities, relay criteria and counts from official sources, and distinguish Japanese cities from towns, villages and the special wards of Tokyo.
A municipality in Japan designated as a city, or shi, under the Local Autonomy Law, generally requiring a population of at least 50000 and urban character, and graded by powers into ordinary cities, cities with public health centres, core cities, formerly special cities, and designated cities with the widest powers; cities are second-level divisions under prefectures alongside towns and villages, and there are about 790 cities.
What it is for: Local self-government in Japan.
It can be explain the category and grades; relay criteria and powers; relay counts from official sources; distinguish from towns, villages and special wards.
