Anko, or anglerfish, look like something from another planet. But despite their shocking appearance, these fish have a rich yet delicate flavor and are known as the main ingredient in anko hot pot, a winter treat. We visit a small village in Aomori Prefecture known for its anko, and witness a giant, once-in-a-year catch. We also discover unique cultural traditions, including a ritual in which anko are filleted on top of snow, plus homegrown dishes based on anko liver, considered a great delicacy.
