Draw Japan’s Municipalities on a Terrain Map

The hard level for Japan. Choose a prefecture, then outline one of its cities, towns or villages, or draw the line between two neighbours. Designated cities count as one unit; Tokyo’s 23 special wards are separate. Municipality names are shown in Japanese. 日本語版はこちら。

How municipality play works

Each prefecture is its own set. Draw a region asks for one municipality’s outline; draw a shared border asks for the line between two neighbouring municipalities of the same prefecture. Borders with another prefecture are played on the prefecture level.

What to expect

Mountain municipalities follow ridges and watersheds; lowland ones follow rivers and old village lines that the terrain does not show.
Border tolerance scales with the question, down to a few hundred metres for small towns.
Ordinance-designated cities (Sapporo, Osaka, Yokohama and others) are played as whole cities; their wards are merged. Units under 3 km² are not asked.

Data

Boundaries come from Japan’s National Land Numerical Information (MLIT, 2025 edition, CC BY 4.0) as processed by Kyodo News and simplified for play; see map data.
