Scrub the mussels under cool water, discarding any with broken or cracked shells.
Heat a large sauté pan, deep soup pot, or wok over high heat with the sake, ginger, garlic, and shallots. When the mixture comes to a boil, add the mussels and cover. Cook for 5 minutes, or until the mussels open.
Toss in the basil and serve immediately.
