Science & Technology

Research of an advance normally costs you 5000 koku. The costs are halved for the scholar personality.

The advances that are colored blue in the techtree are the advances that you receive at start.

Scientific Advances

The following list shows all the advances and their effects.

Regional Advances

Most advances can be studied, but some advances like shurikenjutsu and iajutsu for example can only be received if you own a district that has a famous dojo, or famous temple and so on.

Eras

Not all advances can be researched or received at the same time. Aside from the fact that you have to follow the arrows (i.e. a second advance can only be researched until all the prior advances have been learned), you also have to wait until the start year of that era, before any advances can be researched of that era.
