ELI5: why is the "L" sound often mispronounced as "R" by certain Asian people?

It's always an explanation that ive wanted to hear from a linguist or other expert.

In Japanese, there is no "L".  Hiragana and Katakana (basic writing systems, analogous to the English alphabet) have 40-something characters, most of which are one syllable consanant-vowel, like "ka" or "re".  

In transliterating foreign language words, the letter "L" is most often written as "R", although it should be noted that the Japanese "R" sound is a soft one, not a hard one like in "right".  

So, a word like "Lana" might get changed to ラナ, or "RANA".
