Tokyo in recent years has seen a plethora of specialty coffee roasters (and also coffee specialty cafes.) This is one. It is basically a warehouse facility with a few folding chairs to sit (if lucky) and sip but quite hard to find on a side street off Kiyosumi main street. It's a good hike (15 minutes) from the Kiyosumi-Shirakawa subway station on the Oedo line. If in the neighbourhood, it's worth a stop. The main attraction is to stock up less frequently available types of beans and roast. There are quite a few other attractions nearby (kiyosumi Gardens, Fukukawa museum, Tokyo Contemporary Art Museum, a winery and innumerable small Japanese style restaurants and coffee shops.
