Anno... this thread seams a bit dead but anyway, I've found an interview on dailymotion from when he was promoting OMG (just type in his name and you will find the 5 parts, named A-B-C-D-E) but they aren't subbed and I don't speak Japanese... besides the few words I picked up from watching shows.
So if anyone is up for it, please look it up; he laughs a lot, so I'm a bit intrigued :-)
Arigatou!
