Suzunaan (鈴奈庵, roughly "bell hermitage") is a traditional Japanese style book renter located somewhere in the human village. Although it is a book lender, they also sell books, and even provide a small book printing service. The Gensokyo Chronicle was also printed and bound here. Most of the books they deal in are the books that drifted into Gensokyo from the outside world, which they call "foreign books" (外来本 gairai bon). Kosuzu has been also secretly using some income of the store to gather a collection of rare demon books, and rents out at high price.
