Even crappy chinese singer like Leo Koo get a poster in pacific mall and appears in chinese newspaper but X japan gets nothing in the chinese community in Toronto which is really sad considering they have had concerts in Hong Kong before.
There was a lot of marketing for the HK show if I recall correctly. Posters everywhere, newspaper reports, TV commercials! However, tickets were very expensive so I guess they had to draw in a huge crowd, so the excess advertisement was justified.
Maybe you guys should have a word with the Chinese newspaper or your tourism board 
But then again, X Japan are well known throughout China, Korea, and of course Japan, so the promotion would have been successful, but in the west, X Japan are almost completely unknown, so getting a professional advertising firm to handle promotion for the concerts would prove difficult, because they would see X Japan as not being worth the trouble if no one has any prior knowledge of the group. For example, if a well known group like Metallica or Green Day or whatever had some promotion, a "normal" person would observe the poster and say "Oh cool, I know them, I listen to them, I think i'll get some tickets." But a "normal" person would see an X Japan poster and would say "X...who? Japan? Is this a band? Never heard of them...they must not be good then, Heath? Pa...ta? Yoshi-who?". Therefore, if nobody is aware of X Japan, nobody is going to care, and nobody will buy tickets other than the die-hard fans like us who would already know about the concert without any kind of promotion other than one post on their website.
...well, that might not be why there hasn't been any promotion, but I think its a good argument about why they would not promote in the west until they achieve a larger fan base, and especially until after they release their North American debut album later this year.
