I.....I'm....sorry

I'm playing through Tales of Vesperia at the moment.  This is the first JRPG I've spent significant time on for a few years.  I played more than my fair share (every Final Fantasy except 13 for example ) in the past however and just got generally tired of the genre.

So I went into ToV knowing what to expect and I am actually enjoying it a lot.  One thing thats annoying the hell out of me though is the constant apologizing especially from Estelle. A typical conversation goes something like this:

Someone gets whacked.

Estelle: "I'm sorry for letting you get hurt"

Character X: "I'm so pathetic, I'm sorry for making you worry about me, okay".

Estelle: "I'm so sorry for making you feel sorry"

etc etc etc.

Can you imagine if real life was life this.

Waiting in queue for coffee.

Me: "I'm so sorry for being in front of you in the line"

Random Person: "I'm sorry for not being as quick as you in getting to the line.  I feel worthless"

Me: "I'm sorry for causing you such distress, I'm off to skewer myself on a samurai sword, BTW heres my loyalty card"

Anyway my question is this, is Japanese culture really like this? Do people go around apologizing for nothing all day?
