Itoya Ginza

Heaven for stationary obsessives. Over 7 floors with each floor having a specialization. Off the top of my head, there was a pen floor (just pens!!), crafts, notebooks, home goods - can't remember the rest but this is one of my favorite spots and I go every time I'm in Tokyo. Look for the big red paperclip!

For souvenirs, they sell Itoya products like special-sized Post-Its and giant red paperclips.
