Mountain-kami. One meaning is a mountain deity worshipped by those whose work takes them into mountain areas (traditionally hunters, charcoal-burners and woodcutters), in which case the deity is identified with Oyama-tsumi or Kono-hana-saku-ya-hime. Another meaning is the kami of agriculture and growth who descends from the mountain and is worshipped as ta-no-kami or kami of the rice fields.
