Every winter a lot of tourists come to Fukui to eat Echizen crab, which is called 越前ガニ, or Echizen gani, in Japanese. (Echizen is the name of one region in Fukui and Gani means crab in Japanese.) It’s a well-known Fukui specialty.
Echizen crab is a male snow crab caught in the sea near Fukui. The females are called Seiko-gani, and they’re smaller than Echizen crabs.
