The King of Stationery Shops!
When we visited Tokyo this was one of those places we went back to a few times. My husband is a fountain pen fan, and as it happens, the Japanese are fountain pen aficionados.
Itoya is a fantastic store full of gift and post cards, specialty papers, stationary and writing tools. One floor is devoted to high quality pens and pen sets. There is a nice range of pen brands in all price points. Perfect for gift shopping or picking up a great keepsake from your Tokyo visit.
You can also find lots of nice post cards for dropping notes to your friends back home. Stop by Itoya and enjoy a lovely bit of something all but disappeared from American life- the art of writing.
