Alright, we all know that the English "R" and "L" sounds pose a problem for Japanese people but how do English-speaking people cope with the equivalent in Japanese - the らりるれろ (ra ri ru re ro) sounds? From my experience in Japanese classes, the answer is that most people learning Japanese just don't seem to grasp the right pronunciation of らりるれろ and end up settling for an English R sound. That's a shame because pronunciation is an important part of any language and correct pronunciation not only makes communication easier but, as a bonus, it also helps to make you sound a bit less... well, foreign, to put it bluntly.
With that in mind, I was pleased to come across a video that claims to teach the correct pronunciation of the Japanese R sound in one short lesson. Here is the video, made by Koichi (who is American, by the way), the founder of the Tofugu web site. I'm quite impressed, but I'd be interested to hear what native Japanese speakers think of this.
