Throughout the first millenium of Japanese history (and before that even) the Japanese rather steadily expanded up Honshu. Once they had taken the whole of Honshu however they seemed largely to stop. Throughout the Edo period their dealings with Hokkaido were very limited to just small scale trading posts, there was never any serious attempt to actually expand there until the 19th century.

Why was this? I don't think the Edo period and the need to keep the clans within reach of Tokyo was the whole story as this behaviour predates that too. I've also heard the story that it was down to Japanese rice-based agriculture not working in Hokkaido...but the weather of south Hokkaido isn't all that different to north Honshu. Any ideas?


The people already living in the Ezo, the Ainu, were no joke militarily, and tangled regularly with the Mongolian Empire on Sakhalin, and later, the Ming in the Amur Valley. It's not clear the Japanese could have taken the island completely if they wanted to, not before they modernized in the 19th century.

This also highlights another point - the islands further north were more in reach of the mainland powers. Hokkaido, until the Meiji Restoration, was more useful as a frontier than a destination for colonization.

    The Emishi didn't just roll over and be conquered either. It's curious Japan didn't even try with Hokkaido. The frontier issue however could be a point....I have read that the Sakhalin natives were at least nominally Chinese vassals, could it be Japan was afraid to go after them for this reason? – Lee Jackson May 16 '13 at 5:16
  • historum.com/asian-history/… -- In 1669 the Japanese defeated an Ainu rebellion. After that Ainu had no option but to sell their goods to Japanese (and Japanese only) at prices decided by the Shogunate. They had to sell to trading posts set up by Japanese merchants. – Craig Hicks Sep 17 '17 at 17:28

I think your presumption that Japanese power through military force was not employed in Ezo during Edo is wrong. You may read about Sakushin's revolt and it's suppression in 1669.

UPDATE: 9-18-2017 Here's a much better source Shakushain's War describing the rebellion and going into great depth about the background leading up to and following the rebellion.

Early in the Edo era (~1620) the Shogunate gave the Matsumae clan the right to build a castle on Ezo and the most importantly the right to monopolize all trade there - The Ainu could only trade with Matsumae representatives and it was the Matsumae representatives who decided the prices. This had a great economic impact on the Ainu right from the beginning of the Edo Era.

Interestingly however, the second reference persuasively describes a much more complicated set of circumstances leading to the rebellion: it started out as a feud between rival Ainu clans, which eventually spun out into a rebellion when the Japanese appeared to be favoring one side.

The revolt failed militarily as arrows and spears were no match for the muskets the Japanese were armed with. However, it was a blockade on any trade with the Ainu which really forced the remaining communities to abandon any attempts at resistance. They had long depended on rice obtained through trade with Japan ( since early Edo via Matsumae-clan monopoly only), and without the rice they were starving.

My own conjecture: Originally the Ainu never or rarely ate rice at all. Their population remained bound by the quantity of wildlife they could hunt and the wild nuts and vegetables they could gather. They lived in equilibrium with their environment. Once they started trading captured wildlife with the Japanese for rice, they began to voraciously deplete their natural resources while at the same time thriving on the rice they received in return. This in turn led to feuds between rival Ainu clans as increasing population vied for diminishing natural resources to sell for rice. (The second resource does describe both the competition for resources and the vanishing resources, e.g., bears being unavailable for traditional ritual).

Once this effective domination of the Ainu is put in perspective, one part of the OP's question still remains: Why didn't mass colonization of Hokkaido occur until the Meiji era?

A possible answer to that: Look what happened to Great Britain with their colonists in the thirteen colonies.

    Good information which would benefit from more sources. – Aaron Brick Sep 18 '17 at 2:16
  • @AaronBrick - good point. I found a better reference and added it. – Craig Hicks Sep 20 '17 at 6:21
