Why Umi

Philosophy

Umi was born from a simple conviction: that the best sushi comes not from abundance, but from restraint.

Our chef trained for twelve years in Tokyo — three at a Michelin-starred Edomae house in Ginza, seven at a legendary counter in Tsukiji's outer market, two staging across Japan's coastal prefectures learning from fishermen and fellow shokunin. He returned to San Francisco with a singular vision: a ten-seat counter where every decision serves the fish.

No menus on the wall. No à la carte distractions. Two seatings, one progression. The chef chooses what the sea offers at its peak that day, and the guest surrenders to that choice. This is omakase in its truest sense — "I leave it to you" — a contract of trust between chef and guest.

The Counter

Hinoki cypress. Aged akazu vinegar. Body-temperature rice. These are not details — they are the foundation.

The counter is a single slab of 300-year-old hinoki, chosen for its subtle aroma and natural antimicrobial properties. It breathes with the room, warming to the touch.

Our shari uses a blend of two rice varietals — koshihikari for sweetness, sasanishiki for structure — cooked in a donabe and seasoned with red vinegar aged three years. The temperature is calibrated to 37°C (98.6°F), matching the human body. Each grain remains distinct, never mushy.

Nikiri — our house soy reduction — is simmered for six hours with kombu, katsuobushi, and a touch of mirin. It glazes each piece of nigiri with a whisper of umami, never drowning the fish.

Wasabi is grated fresh to order on a samegawa (sharkskin) grater, releasing volatile aromatics that vanish within minutes. We serve it between fish and rice, the traditional Edomae way.

Chef Yuki Tanaka

"Sushi is not about the rice, nor the fish alone. It is the moment they meet — temperature, pressure, time. That moment cannot be repeated. It exists only once."

Born in Kanazawa, Chef Tanaka grew up in his family's ryokan kitchen, learning the rhythm of the Sea of Japan's seasons. At eighteen, he moved to Tokyo to apprentice at Sushi Saito, then Sushi Yoshitake. His philosophy: shun no kokoro — the heart of seasonality. He believes the chef's ego must disappear; only the ingredient should remain.

At Umi, he works alone behind the counter. No assistants. No pre-made components. Every slice, every brush of nikiri, every grain of rice passes through his hands. This is the luxury of ten seats.
