G.Itoya

If you just can’t get enough of stationery, this store is your happy place. Spread across 12 floors, G.Itoya sells fancy fountain pens, diaries, fine paper and so on. The first eight floors are reserved for shopping and are divided by function ('home', 'desk' and so on), while the tenth floor has space for meetings and the 11th boasts an urban vegetable farm with salad grown in very high-tech bins; the greens are then used in dishes served in the slick café one storey up. Pick up some essentials for your work or studyplace here, or just a well-made postcard to send to someone back home. They also have an annex, K.Itoya, located right behind the main building and stocking even more Japanese-style stationery supplies, calligraphy goods, art tools and globes.
