Mix all the ingredients of the dipping sauce. Set aside.
In a pot, put dried Kombu in the water, and let it sit for 15 minutes.
Cut meat into the size you like. Cut cabbage into 2" width pieces, slice white long onion diagonally, cut off the stems of Shiitake mushrooms, and cut Kikuna (Shungiku) into 2" length pieces.
Heat the pot at medium high heat until the water boils, then take the Kombu out. Turn down the heat to medium low. Add Sake.
Dip the meat in the simmering broth until the color turns pink. Cook meat and vegetables as you eat.
