Maries' fir (Abies mariesii, in Japanese, オオシラビソ or アオモリトドマツ, Oh-shirabiso, or Aomori-todomatsu) is a fir native to the mountains of central and northern Honshū, Japan. It grows at altitudes of 750–1,900 m in northern Honshū, and 1,800–2,900 m in central Honshū, always in temperate rain forest with high rainfall and cool, humid summers, and very heavy winter snowfall. Maries' fir is very closely related to Pacific silver fir A. amabilis from the Pacific coast of North America, which is distinguished by its slightly longer leaves (2–4.5 cm) and larger cones (9–17 cm long).
