WI: Sengoku doesn't end

[some kind of chimp]

What if the Sengoku (warring states period) never ended in Japan? Say that coalitions of the smaller warlords would take down any strong challengers (Oda Nabunga, Toyotomi, Tokugawa, etc) and then promptly collapse.

So Japan is still divided into a bunch of warring statelets. How long could it have lasted for, and what would the effects be on 19th-century colonialism?

If it lasts until colonization, Japan may be easy picking. Say, a Dutch Kyushu; Russian Kuriles, Sakhalin, and Ezo; and maybe (setting up a butterfly net) a British Honshu. Possibly British Kyushu as well.
