In shallow dish, combine miso, rice vinegar, sake, light brown sugar, sugar, soy sauce and ginger to create marinade. Place salmon skin up into dish and marinade for at least 30 minutes and up to 2 hours.
Preheat oven to 400°F.
Remove salmon and shake off excess marinade. Place fish meat up on baking dish or roasting pan lined with aluminum foil and bake for about 10-12 minutes. Toast bread crumbs in non-stick pan for about 2 minutes till golden brown and then sprinkle on top of salmon about 2 minutes before fish is done. In small saucepan, warm the leftover marinade into a condensed sauce and drizzle on or around your salmon.
