Mount Achiru

Mount Achiru [あちる山; あちる・さん] is a mountain located in western Uchi Prefecture in the Senshin Hills. It is the second-tallest in the prefecture after Mount Seishū, standing at around 1,450 metres. Mount Achiru is the source of the Sakayami River and its tributary, the Amizu. 
Mount Achiru's name comes from a local dialectal word meaning 'autumn foliage', most likely referring to the scenic beauty of its forested slopes in autumn.
