Mythological and legendary Japanese snakes

Takeminakata (タケミナカタ), also known as Minakatatomi or Takeminakatatomi, is a kami in Japanese mythology. Also known as Suwa Myōjin (諏訪明神 / 諏方明神) or Suwa Daimyōjin (諏訪大明神 / 諏方大明神) after Suwa Grand Shrine (Suwa Taisha) in Nagano Prefecture in which he is enshrined alongside his consort Yasakatome, Takeminakata is historically worshiped as a god of wind, water and agriculture, as well as a patron of hunting and warfare, in which capacity he enjoyed a particularly fervent cult from various samurai clans during the medieval period such as the Hōjō or the Takeda. Takeminakata was also held to be the mythical ancestor of certain families who once served at the shrine as priests, foremost among them being the Suwa clan, the high priests of the Upper Shrine of Suwa who were also revered as living vessels of the god.

Yamata no Orochi (ヤマタノオロチ, also written as 八岐大蛇, 八俣遠呂智 or 八俣遠呂知) is a legendary eight-headed and eight-tailed serpent that appears in Japanese mythology. Both the Kojiki and Nihon Shoki record the serpent as being slain by the god Susanoo, in order to rescue the goddess Kushinada-hime. It is also noted that the Kusanagi-no-Tsurugi, one of the Three Sacred Treasures, was found within the serpent's tail.
