This is also why the Jedi (at least in the earlier films) use two hands to hold their lightsabers. It's the Japanese style. Of course, Samurai swords were two-handed because they were heavy, due to the poor quality of steel available. A light saber "blade" would presumably weigh nothing, so it would make more sense to hold it one handed like a, well, saber.
A master of the more technologically advanced European saber would probably cut a Katana-wielding Samurai to ribbons. Good thing the Samurai would probably just shoot him from horseback anyway.
