The land on the map of the game is divided into 1031 grids. These grids are the regions or districts in the game and are also known as kori. You can build one town on each district that you own. Districts vary according to terrain and climate.
The following list shows how many districts there are for each type of terrain:
Some towns can have harbours or ports. Harbours or ports can only be constructed where the terrain of a district is a beach.
There are 35 harbours in Japan.
Some towns can have guilds. Mountains with deposits like iron sand, copper, silver or gold can have guilds.

Climate affects the weather in the game and weather in turn may affect battles.
A wet season means that rains are frequent in that climate zone. Rain and snow negatively affects the strength of missile units.
The following table shows the effects of climate on weather, where to find that climate, and the odds of a typhoon occuring in the area where that climate is to be found.
