Thanks for your replies, all.
I'm surprised, given the inroads luxury items have made into the culture (I'm talking about the US), not to mention the broadening of available cuisines (noting esp. the popularity of Japanese food), that there isn't an obvious market here for Japanese distillers to tap. I can apparently order Yoichi on-line from the UK (from royalmilewhiskies.com, for example) if I wanted to swallow the shipping, or I could drive to Canada (not an option; is there no where I can order from Canada? I gather from a cursory google search that their liquor sales are pretty well state-controlled), but why go through all that on a gamble? I haven't even tried it. But I'm intrigued. I've tried the Yamazaki 10 and found it too sweet for my taste; I have yet to try, but suspect the same from, the 18. But then I read the glowing reviews of some of the peaty Yoichi expressions at this site and ... not an option. Frustrating.
