2. The conventional reading of the personal name on "Sawada" is Kenji.
But we are talking about two separate people, right? Despite conventional readings, KenYA has been billed as such in English in most of his Hong Kong movie appearances. KenJI hasn't had any connection to the HK film industry that I know of.
I just have difficulty believing that the "other" Kenji (well, to me the only one, really), a
nearly 60-year old Japanese pop musician (and sometime actor) would suddenly start
writing Hong Kong movies. And yes, I'm aware that anything's possible, but I'll see what I can find.
My suspicions, for the record, are that this Sawada chap is a newcomer, like this fellow, perchance...
