Have you ever done haiku ? We should use Kigo when doing haiku. Kigo is a seasonal word. Monkfish or Ankou in Japanese is a winter season word in haiku. For example, a great writer, Natsume Soseki(1867-1916) composed a haiku using Ankou as a Kigo. That one composed by him is written "Ankou is being cut hanging as if it were a pregnant woman." The body of Ankou is squishy so the hanging method is used when cutting instead of using a cutting board.
In Japan, there are various kinds of hot pot dishes. Ankou hot pot dish is popular especially in the eastern part of Japan. Speaking of another one, Tecchiri in Japanese or blowfish hot pot dish is popular as well. Tecchiri originated in the western part of Japan so it is said that Ankou nabe(hot pot dish) is the Eastern Grand Champion and Tecchiri is the Western Grand Champion. Finally, he or she will be introduced.
