afraid it ain't as straight forward as it seems. unless you are of japanese origin
yourself, it will be extremely difficult to detect through a few simple phrases whether
or not the girl is a true blue JG.

of course, unless the girl is completely unable to speak a word of japanese, you will
probably still be disadvantaged. most of the 'JGs' on the DB are either from korea or
the mainland but many have done stints in japan before or have one way or other,
acquired the linguistic ability to speak japanese.

but i guess my perception on this whole JG authenticity issue has shifted alittle. if
you think she is hot when you see her at the door and is worth your 1400HKD+, then
go for it. but i wouldn't really be hung up about her not being a real JG. if the corelation
is purely based on the price tag to whether the WG is a real JG, then i would
suggest just to hit the 700-800HKD range, cheaper and likely, hotter as well.
