I added a couple of reviews a few weeks ago, though only for my purchases within the past one year. Some of them were for Japanese merchants:
Classe - http://www.cosplay.com/showpost.php?...postcount=2394
Lovepop (Classe dealer) - http://www.cosplay.com/showpost.php?...postcount=2395
Neither review is groundbreaking, since Classe had a great reputation already, and you wouldn't imagine their authorised dealers to be horrible either. That said, as I ordered through a shopping service, I didn't actually deal with them; I could only comment on the state of the products and the time it took to reach the shopping service's warehouse.
The shopping service I used was pricey... But I don't feel it's fair to make a relative or friend act as the middleman. I wish my mother's job takes her to Japan more often again :s
