As the Warring States period came to an end, a town-building boom saw rapid growth in lumber demand, leading to destructive lumbering throughout the country.
The early Edo period saw a growing crisis concerning forest resources, which had supported the local economy, in Kiso.
The Owari Domain, which had jurisdiction over the Kiso Valley, issued a forest conservation policy that mainly prevented logging.
Kiso people found different ways of making a living in new local industries.
In the late Edo period, improvements were made to the road and a growing number of people visited Mt. Ontake. They made local specialties, such as Kiso lacquerware from the post towns, popular nationwide. The Kisouma (Kiso horses), Kiso-hinoki cypress, and traditional crafts, such as Kiso lacquerware, that made Kiso known throughout the country in the Edo period are still part of the Kiso Valley and synonymous with Kiso.
