''For a Japanese house, I'm surprised that I can't seem to locate this, ummmmm..... ANYWHERE around where I live (and I live in Kobe, not a small or out of the way city by any stretch of the imagination), including the local Barney's New York that only stocks like 4 houses (seriously). Their official website isn't that helpful either.''
(Sorry! I didn't use the 'reply with quote' button!!) They usually have it at CdG boutiques (clothing/fashion) rather than fragrance shops/counters. I often drop by the one in Shibuya for a test shot. Even the boutiques inside department stores have it, I think, at least that is the case at Isetan Shinjuku. They seem to circulate their stock around, so you might not find everything at once. But the staff at the shop might be helpful in locating a particular name.
(Barney's in Shinjuku is not such great shakes either)
