Aoshima Shrineあおしまじんじゃ

Also known as Amatsuhikohikohohodemi-no-Mikoto. In the Umisachi-Yamasachi myth, he visited the sea palace guided by Shiotsuchi-no-Kami. He married Toyotamahime and used the tide jewels to subjugate his brother. Breaking the taboo of looking led to his wife's departure, but their lineage established the imperial family tree. Venerated at Udo Shrine.
