That's harakiri, samurais kill themselves by cutting across the stomach.

I got confused in the # and just figured there was more then on way of saying it.

How did he miss?

Seppuku is a samurai suicide honor code thing and they use the sword and they aim for the belly button.

Really? Because I read that they cut from left to right the only problem I saw is that he was going the wrong direction

I've learn that is now hara-kire you can see from shinobideus 's post.

...suppose I should explain the difference.
hara-kiri means about 'cross cut'
In hara-kiri you cut yourself across the stomach and wait to bleed out.
In seppuku, you stab yourself in the stomach and have an associate behead you. The associate often then commits hara-kiri himself.
