Quite true but then the inflection is different too... we say "Ah KEY rah" Kurosawa while they seem to say it "AH key rah". Then there is the "F" which can often sound like an "H" and "D" and then there are the long vowels which are simply said longer (we don't use durration so often don't notice it, but it makes a big difference... for example, the long O is often written as OU, OO or just an O with a ¯ over it, but we often drop this distinction when we write or say "Tokyo" and "gyuto", which both have long "O"s and should be written Toukyou or gyutou. But, then there is "Koumon", with a long "O" it means "advisor", but if you don't pronounce that "o" long enough, it means "anus")
