If you're making a samurai character, another thing you may want to include is the "Bushido" code of conduct. If i remember correctly, it's a 5 bp positive quality that gives some slight bonuses. I think it also requires your character to increase a knowledge skill before you can increase any active skill, or some kind of mental+physical tie in. Personally, it seems to me like too much of a hinderance, but if you want to really make a character who follows a samurai lifestyle, it's an option.
