Went to the sand dunes of Tottori yesterday, only saw a handful for foreigners.
But today I arrived in Kinosaki Onsen, and there is a lot of westerners walking around in the streets here.
Not sure what draws people this this location exactly, but maybe it is the easy access with limited express trains from Osaka, Kyoto and Himeji?
I arrived on a local train from Tottori, with transfer in Hamasaka which was quite "local" as expected. ;-)
