In a bowl, whisk together the sake, rice vinegar, soy sauce and ginger. Heat a large skillet over medium high heat. Add the oil. Sprinkle the top of the fish with with the sugar. Once hot, add the salmon, skin side down. Sear for 2-3 minutes or until the skin is crisp. Carefully flip the salmon and cook another 2-3 minutes or until the salmon has caramelized slightly. Carefully remove the salmon from the pan.

Wipe the skillet clean of any grease and add the teriyaki sauce. Bring the sauce to a boil and cook for 3-5 minutes or until the sauce has reduced by a 1/3. Add the salmon, skin facing up. Cook two minutes and then remove from the heat. Serve the salmon along side the buckwheat and drizzled with the teriyaki sauce. EAT!
