You can see where he is located from his Reverb ad. Go on Facebook Market place, and enter his locale, then search "Tokai". If he's on marketplace, you can contact him, through F.B., and exchange direct emails, or phone #s.
You can do the same thing looking on Craislist for his area.
He may have an ad on ebay. Often sellers use the exact same item description, for their other ads for the same guitar, wherever they put it up. If it's on ebay, searching for "Tokai EGF-1800" will surely bring up the ad there. On ebay, they scan emails for folks exchanging contact data, to circumvent eluding ebay's surcharge, but you can let him know your interest, and have him contact you through our forum.
It sounds though, like some of our friends here on the forum, know him, and perhaps one of them, Oh I guess that could be me, could send him a note on Reverb, letting know to look you up here. If no one jumps in, I'll see if I have time tomorrow.
I also wouldn't be surprised if he sees this, thread on here, with his own peepers, and contacts you.
Good Luck,
I was reading one of our thread/s about these, or possibly this exact one recently. They sound like fantastic guitars !
