Ran into a Canadian here in Tokyo that managed to find a Switch in stock at Yodobashi. With the 5% Visa discount and tax free it was about $340 CDN here. Used stores are reselling them for a pretty hefty mark up along with PSVR and the Famicom Mini.
I couldn't find at Switch myself - but I did get a Famicom mini though. And maybe some used games or two . . . this place is amazing for gaming gems.
