Owned by Kinokuniya but usually in a separate location, these stationery stores carry the kinds of supplies found in Japanese stores. Japan is serious about stationery. In here you will find everything from Gelly Roll pens and Sanrio stamps to sumi brushes and fabulously expensive traditional washi paper. Their actual stationery is quite beautiful, with lots of nature and floral themes. A little expensive, but you do get coupons toward future visits. Addictive if (like me) you can't get enough of this kind of thing.

Now if only I had people to write.
