I am confused as to why your potted history indicates that Meiji Japan is a bad example of successful westernisation.

• On first contact, Japan unwisely attempts to shut out the Westerners, and stagnates for centuries, leading to the humiliation of Bakumatsu. This could easily have ended in the destruction of the Japanese nation; not copying the West was a disaster.
• Seeing the need to avoid that fate, the Japanese showed the flexibility and wisdom to reform their nation. They quickly copied the ways of the West, which was a roaring success for Japan; they not only avoided destruction, but managed to defeat Western powers (e.g. Russo-Japanese war). Yes, they became an "imperialistic oppressor" (your words) to their neighbours. So what? The question is how should a people facing colonization act, not how should their neighbours hope they act.
• Despite the destruction of WW2, Japan quickly rebounded, becoming even more Western, and even more successful. Yes, things aren't perfect, no, they aren't doomed, they are one of the richest and most successful countries in the world. The Cree Nation would kill to have their problems.
