Yamazakiya

Descend the stairs to this cramped basement liquor shop specialising in sake and wine, and you just might get your hands on some real rarities. Their hand-picked selection includes plenty of hard-to-get nihonshu, with offerings from western Japan and Kyushu especially well-represented. They also sell local and/or organic foodstuffs, with everything from olives to eggs found in one corner, and natural cosmetics taking up another.
