Onigaze - Onigaze

Recently, aquaculture has been practiced, whereby eggs are fertilized, and young sea urchins are artificially raised on land until they reach a diameter of about 1 cm, and then released into the sea. In local areas, Ezo-bafun sea urchins are often called Gaze or Bouzu-gaze, Kitamurasaki sea urchins are called Nona, Murasaki sea urchins are called Kurogaze, and Aka sea urchins are called Onigaze in local dialects. [Minoru Imajima]
[Folklore]
The words "kase" and "gaze", which remain in local names, are old names for sea urchins, and in the past they were written as "rei-ga-shi", "ko-tsuke-ga-shi" and "ko-tsuke-ga-shi".
