Japanese language setting for any of the Katamari games?

[cranguy]

Is there a way to switch to a Japanese language setting for ANY of the Katamari games? (PS2, PSP, or 360)

I may be going crazy in my old age, but I seem to recall playing it in Japanese at one point. Maybe it was just a video and my brain got them confused -_-

Any tips appreciated. I'm hoping to beef up my Japanese vocabulary a bit.
