Here is a different kind of backpack from Thanko Rare Mono Shop.
This backpack can carry a pet inside and has a transparent astronaut-like helmet cover from which your pet can peek out. The backpack has holes on the side and uses material that keeps the inside well ventilated. There is also a small chain that can keep your dog from slipping out.
Comes in black and white, and costs 5,980 yen.© Japan Today
