Michael, TT poster Goldenyama was familiar with the line, owned a few, and was living in Japan a few years ago when these (fascinating) frames came up for discussion. I'm not sure he's still around, though. As you've probably seen, there are a few of them on the auction site that (you can tell by the photography) were previously being sold in-country on the Rakuten.
I'd especially love to own an EX-110G or two. That's the lowest-powered and (If my understanding is correct) thinnest-beamed of the three Gabby post-Prince Yamahas, the white one with black and silver stripes reminiscent of the Head Microgels. The earlier white EX-110 and yellow EX-110 Tour do look a little cooler to me than the 110G.
Foe those concerned with weight, there was a Japan-only FX series that was lighter. Probably some others, too.
