Learning a foreign language is hard. Even if you master all the vocabulary and grammar, there’s still no guarantee that you’ll ever achieve a native-like accent. For Japanese learners of English, differentiating between the “l” and “r” sounds and pronouncing the “th” sound correctly can be tricky them no matter how many years they’ve been practicing.
But have you ever wondered what it’s like the other way around? What sounds do we English speakers make that sound strange when we speak Japanese? Well it turns out the sound that we mess up the most is one you might not have expected: “fu”.
