AGAIN, I LIKE THE ROLLED R. A LOT-- *shot*
Hayao half has them XD
Anyway, no, these are still English Rs.
It's more of a l than an r, remember that. ^^'' I wouldn't go as far as to say that an is an l, because it's REALLY not... But a good start to saying the Japanese R is to start with more of an l position...
But then, instead of sliding to tongue over the roof of your mouth, too get that slurry "lll" sound, change to a quick d-type movement.
Basically, explaining it like that makes no sense XD /half asleep.
But yeah, if I really had to choose out of L and R, an L is closer to a Japanese "r" sound ^^''
