Are フィ、ファ、フェ and フォ still pronounced with a bilabial fricative or just a normal English "f"? I know that is pronounced with a bilabial fricative, which is different from an English "f" or "h". However, in there are some words containing things like and . e.g. . Seeing there is a in there, I am wondering whether I should do a bilabial fricative or the English "f". Can Japanese people pronounce English "f"s?

Both sounds are allophone and recognized as the same sound but English "f" sounds a foreign accent. Even if the speaker is familiar to English sound, s/he won't pronounce it with English "f" because is Japanese.
