What were the differences between European model of feudalism & the Daimyo system in Japan? I’m no expert, but from what I have seen it seems that the Tokugawa Bakufu exerted a lot more absolute power over the Daimyos than any European overlord, being able to sentence Daimyos to commit seppuku or confiscating their domains at will. Would really like your views on this.

Those are quite distinct models, but the important thing to keep in mind is that the Tokugawa shogunate was very much a reaction – building upon the legacies of Odo Nobunaga and Toyotomi Hideyoshi, to be sure – 

to the complete lack of central authority during the Sengoku Jidai. 

So it wouldn’t be an apples-to-apples comparison. If you wanted something more similar to the Tokugawa Shogunate, maybe something more like the regimes of Henry VII or Cardinals Richelieu and Mazarin. On the other hand, if you wanted to look to the weaker feudal monarchies of Medieval Europe, a good comparison might be the Taira-Minamoto wars or the Sengoku Jidai itself.
