Jimbocho
Jimbocho is the area in Tokyo famous for its bookshops. My personal favourite was the cat speciality bookshop where the owner was very keen to see pictures of my cat (thinking about this actually, this wasn’t even the only time this happened on the trip). As well as books (obviously) it had stickers, magazines, bookmarks, calendars… a great place for gifts. As well as this gem there were a good few others, some of which had small English sections to browse through.
