Yeah but their R sound sits between an R and an L sounds. They don’t have a separate L and R sound. Hence when they transliterate foreign words they use ラリルレロ both for L and R sounds. It’s why Japanese mix up their Rs and Ls when they talk or write a foreign language like English or Spanish. It’s much harder for them to hear the difference since they didn’t grow up hearing L and R as separate sounds. But also the way they learn foreign languages doesn’t help either. Since they use their kana system to learn pronunciations.

But non native Japanese speakers also have a hard time pronouncing the R the Japanese way. It’s like a rolling R but only a single tap to the palate.
