I've seen on twitter a photo of a cat carrying a shamisen, with the text ねこや ("nekoya", literally "cat shop"). There's a phone number underneath of (351) 1647. The store's address is 3-6-4, yotsuya, shinjuku-ku, Tokyo (source)
What is the shop selling? Is it selling shamisens (as apparently claimed here) which are traditionally made using cats, a cat cafe, or something else?
