The left is called Oyaki. I think it is originally from Nagano prefecture... The reason ? Because I have seen them on the highway service areas and it was usually within Nagano area.
Also, there were three flavours. The middle was Nozawana zuke ( pickled nozawana -- green veggie ). It is also originally from Nagano prefecture. The taste is like mini pancake. I bought the one with Nozawana.... good snack !
Others were purple sweet potato and eggplant & miso paste. ( That sounds good also).
This lady is selling Yakitori --- grilled chicken. There were varieties.... bones, skins, thigh, wing.....I had thigh stick... 100 yen each.
