You owe me a little money still.
It's 13 million yen!
Sorry, clairty isn't important. LOL!

I have literally seen cases like this.
Sorry if culture clash is lost upon you.

EDIT:
Phrasing generally understates anything that may be taken negatively and overstates anything positive (unless it's about yourself, of course).
It does not matter if the *actual* case is extremely negative, unless they are being angry then they will understate it as a matter of being polite.
Even if said case is exorbitant, it is considered a matter of being polite which is a higher priority than clarity. This is just a difference in culture.

That doesn't mean the prices are reasonable, it's just the statement is something you would expect given the context.

No I understand, the language thing is a problem - however - I am sure YoshiP knows the difference between a little of something and a lot of something.

He said a little, difference, when in fact we're paying more than double.

'Slightly' is a much more acceptable PR than 'You will be paying more than double'.

Yes, you're right about PR but I just mean most JP companies speak in a very polite way to their customers.
That may come across as misleading, but it's not exactly PR fluff either.
No doubt that understating something that may make your customers upset is better PR, but I can't really seem him saying "you will have to pay a lot more" as it will sound too confrontational.
The decision is questionable, but there was no other way he would of said it after making said decision.
