Walk into a Japanese bar and, inevitably, you’ll be served a tasty little morsel to tide you over until your drink is served. Known by a variety of names—o-tsumami, o-toshi, sake no sakana—these appetizing hors d’oeuvres are derived from the first course of kaiseki (Japan’s haute cuisine), known as hassun. They take the form of small, taster-sized servings in attractive ceramic bowls or plates, and are a delight to behold and consume.
Dedicated drinkers, the cognoscenti of o-tsumami, are sometimes known as hidari kiki (left-handed) or sato (“party of the left”). These terms owe their origin to a Chinese classic on manners, Li Chi. According to this volume, said to be the origin of Japanese ideas on table settings, soy sauce and food should be served on the right side of a diner, and all liquor on the left. Thus the left hand is used to hold a glass, and to prefer the left came to mean to enjoy drinking.
Half the fun of food, for both guest and cook, is the pleasurable anticipation—what ingredients will be used, and how will they be prepared? When creating o-tsumami you can really let your creativity run wild. Just about any food can be used, as long as it is pleasing to look at and delicious. It should encourage the appetite and the thirst, so the flavors and seasonings are usually bold.
Here are some guidelines for popular and easily made o-tsumami combinations. These dishes can be prepared in advance and served cold or at room temperature, or thrown together quickly as your guests arrive, using whatever you have on hand. Increasingly o-tsumami are often a curious blend of multicultural cooking; a combination of East-West flavors is neither unusual nor looked down upon. Try some of these variations at your next party.
Fried Wonton Salad:

Steamed Clams in Sake:
- Saute small fresh clams in the in sesame oil for a minute or two.

Grilled Japanese Mushrooms:
- Lightly salt (for best results, use sea or kosher salt) shiitake, shimeji, or other fresh mushrooms, and grill until done. Alternatively, brush lightly with soy sauce instead of salt. You can also try grated fresh ginger over soy sauce-flavored mushrooms for another layer of flavor.
- Serve with lemon wedges.
Green Asparagus Kimpira:
