Citibank JP has chipless CCs but issue a pin. The only place that I have used it in Japan is for buying train tickets from machines. Oh yeah, I was in a remote place in NZ where I needed to buy gasoline. Even though the station was manned they required a pin cc transaction to purchase fuel. So my JP CC came to the rescue. Also used it to buy a train ticket from an automated ticket machine in Denmark. These countries (definitely DK) are primarily chip+pin but clearly mag stripe + pin works fine too.

US CCs also have pins but it is usually meant for using the card for a cash transaction where they hit you with fees. And you usually have to request the pin. In Japan Citi issues two pins automatically. The other is for online account access, I think.
