noun
large, high mountain
Rare term; often appears in proper nouns such as 御嶽山 (Mount Ontake).
御嶽山は長野県と岐阜県の境にある大きな山です。
Mount Ontake is a large mountain on the border of Nagano and Gifu prefectures.
The prefix 御 (み) is honorific, and 嶽/岳 (たけ) means 'mountain peak'. The exact historical derivation is uncertain, but it is used in classical and religious contexts for revered mountains.
