Come see the famous poplar that starred in a classic 1970s Nissan commercial, a true icon of Biei's rolling hills. Standing tall and solitary, the Tree of Ken and Mary is a picture-perfect spot, offering a touch of nostalgia against a stunning landscape. It's an easy stop right by the road with parking nearby, perfect for grabbing that memorable photo, especially when the surrounding fields are blanketed in snow during winter or lush with greenery in the summer.
