J-List pays a lot of attention to what awesome products from Japan our customers are most interested in. For example, we have a report (J-List version here, JBOX.com here) that tells us what keywords people are searching for, so we know to stock lots of Touhou, Tenga, Evangelion and shimapan products for everyone. I also like browsing all J-List products in "wishlist" order, which shows us what products customers are adding to their J-List wishlists and lets us judge relative popularity of all products. You're almost guaranteed to find something you didn't expect!
