They only have a couple extra keys when they need maybe an extra row. (IMO unnecessary) Trade offs have been made, like in most non US latin languages, for compatibility with the US keyboard layout. It is similar to the European keyboard layout where it is painfully obvious that they would have a much more efficient layout if they just added more keys, but they chose not too because then it would differ too much from the US standard.
