how is imperialism shown in the Last Samurai?

Answer 1

I assume you mean the movie?
Well the traditional culture of the land is being replaced by Western values. Samurai, once honored and feared, are seen as outdated, useless, and dangerous. Isn't there a scene where a man if forced to cut off his traditional knot? That would be a Western / imperialist value being forced upon a person. The guns and cannons...doesn't get any more imperialistic than that, the old warriors are destroyed because they refuse to conform with Western ideas of "modern" or "progress."
