Sugamo, on the JR Yamanote line, is popularly known as "Grandma's Harajuku" (obaachan no Harajuku), and indeed most shops in the area do seem targeted towards a geriatric clientele. For the (rare) tourist, however, this means a plentiful supply of tea, pottery, kitchen implements and clothes in styles that went out of fashion 50 years ago. The area is at its liveliest on the 4th, 14th and 24th of each month when a street market is held.
In Sugamo MacDonald, all the menus are used only Japanese instead of using English Japanese. Example: Potato=Oimo S.M.L=syou chu dai)
