"R" spunds like "D"?

To be honest, in Japanese. Does "R" sounds like "D" sometimes? Like for example English Car Japanese Kuruma Could it be sounds like "Ku-du-ma"?

Ooops, I misspelled "sounds" from the subject.

Kingdom-san, :P YES !! Actually, the Japanese "r" is a cross between the English "r" and "l", and quite interestingly, it winds up sounding close to a "d"!! The sound "r" is made by lightly flicking the tip of your tongue against the ridge behind your upper teeth, a bit farther back that when saying "d".

If any of you also speak Spanish, I noticed it is very similar to the Spanish "R" which is what I use to impress my Japanese tutor.
