At a discreet sushi counter in Tokyo, the choreography is familiar: a polished wooden bar, the rhythmic glide of a knife, the gentle brush of nikiri. But instead of glistening tuna or translucent squid, the chef shapes marinated shiitake, delicately seasoned kampyo and cucumber layered with kombu umami.
This is not a novelty tasting menu, nor a compromise. It is a fully realised vegetarian and vegan omakase, and it signals a subtle but significant evolution in Japan’s most revered culinary tradition.
The experience comes from Tokyo-based travel and interpreting company Tabimori, Inc., delivered through its long-running sushi interpreting service, Sushi University.
Since 2017, the service has helped international visitors navigate the rituals and nuances of Edomae sushi with expert linguistic and cultural guidance. Over time, however, a clear pattern emerged.

“We welcomed many guests, but some could not eat raw seafood for various reasons,” explains Tetsuya Hanada, Managing Director of Tabimori. “Others were pescatarians, some could eat eggs but not seafood, and others avoided specific ingredients. We accommodated these requests individually. This experience made us realise that even those classified as vegetarians or vegans wish to experience authentic Japanese sushi culture.”
The result is the Authentic Vegetarian & Vegan Omakase Sushi Course: a two-hour counter experience priced at ¥16,000 per person, inclusive of interpreting services and hotel pick-up. Crucially, this was not conceived as a reactionary nod to global wellness trends. “It was primarily driven by traveller demand,” Hanada says.
BEYOND SUBSTITUTION

Omakase — “I leave it up to you” — has traditionally revolved around seafood craftsmanship: ageing, curing, marinating and seasoning fish to reveal its inherent character. The central question for Sushi University was whether that integrity could survive without fish at all.
Hanada insists authenticity was never negotiable. “We never stray from the fundamentals of nigiri and Japanese cuisine,” he says. “Authenticity is preserved by upholding the sushi chef’s pride and technique.”
Rather than constructing plant-based replicas of tuna or eel, the chefs return to first principles. Edomae sushi developed in an era before refrigeration, relying on techniques such as salting, steaming, simmering and kombu-marination to deepen flavour and extend preservation. Today, those same methods are applied to vegetables.
Salting tempers bitterness in leafy greens. Gentle heating coaxes sweetness from root vegetables. Kombu marination, or kobujime, lends quiet depth. Fermentation and miso introduce savoury complexity without excess.
“Plant-based ingredients such as shiitake, menegi, kampyo and cucumber have always existed in sushi culture,” Hanada notes. “The concept is not new; it is simply being repositioned.”
Each course is structured as a complete omakase narrative rather than a sequence of vegetable toppings. Guests sit at the counter, observe the chef’s movements and engage in direct dialogue, supported by an interpreter who explains provenance, etiquette and culinary philosophy. After the signature course, diners may request additional pieces or create original combinations — a privilege usually reserved for trusted regulars.
THE PHILOSOPHY OF FIVE

If seafood is absent, what anchors the experience? The answer lies in washoku’s enduring framework: the Five Tastes (gomi), Five Colours (goshiki) and Five Techniques (goho). Together, these principles govern harmony in flavour, visual composition and nutritional balance.
Sweet, sour, bitter, salty and umami are drawn not from fish oils but from seasonal produce, sesame, miso and seaweed. White daikon, deep green shiso, golden plant-based preparations, inky nori and vivid red vegetables create visual equilibrium. Raw, simmered, grilled, fried and steamed techniques provide textural contrast and aromatic nuance.
Japan’s culinary history offers precedent in shojin ryori, the plant-based cuisine of Buddhist temples, long guided by seasonality and restraint. In this context, vegetarian omakase feels less like disruption and more like rediscovery.
“A vegan omakase is not just about offering vegetable sushi. It is a fully designed, tailored omakase course built around plant-based ingredients while preserving Edomae fundamentals” — Tetsuya Hanada
“With the government aiming to increase foreign visitors to 60 million by 2030, accommodating vegetarians and vegans will become increasingly important,” Hanada says. “Plant-based omakase allows Japanese cuisine to remain inclusive and relevant while preserving core values such as seasonality, craftsmanship and respect for ingredients.”
Globally, plant-based dining has moved from niche to mainstream, particularly in fine dining. Michelin-starred kitchens across Europe and North America now foreground vegetables with the same reverence once reserved for protein. Sushi, however, has remained closely associated with premium seafood.
By reinterpreting omakase through vegetables while retaining Edomae discipline, Sushi University positions itself at the intersection of heritage and future-facing luxury.
REDEFINING OMAKASE

The term “omakase” has, in recent years, been stretched thin and applied to everything from dessert tastings to cocktail menus. Hanada sees this course as an opportunity to restore conceptual clarity. “A vegan omakase is not just about offering vegetable sushi,” he says. “It is a fully designed, tailored omakase course built around plant-based ingredients while preserving Edomae fundamentals.”
During development, the team grappled with philosophical questions. Should plant-based sushi mimic seafood — grilled aubergine standing in for eel, for instance — or establish its own sensory language?
“One issue is that plant-based foods often taste bland to the average person,” Hanada reflects. “For a single dining experience, people mistakenly perceive dishes high in fat, salt and strong sweetness as delicious.”
Ultimately, restraint prevailed. Rather than imitate seafood, the chefs chose to amplify the inherent umami and gentle sweetness of vegetables, incorporating nutrient-rich Japanese ingredients such as miso and sesame to ensure balance.
“We decided to let guests enjoy the classic foundation of nigiri sushi,” Hanada says. “I believe these discussions and repeated trials provided wonderful stimulation to the chefs’ sensibilities.”
In this framing, vegan omakase becomes less about restriction and more about refinement — an exercise in drawing out nuance through discipline.
A LUXURY EXPERIENCE, REFRAMED

The experience unfolds over approximately two hours, from pick-up to concluding at selected sushi counters across Tokyo. Reservations are required in advance via Sushi University’s online platform, where guests complete a questionnaire clarifying dietary preferences — vegetarian or strictly vegan — ensuring precision and respect.
For luxury travellers, the appeal lies as much in access as in ingredients: counter-side conversation with a sushi master, seasonal produce sourced from markets including Toyosu and regional vegetable stands, and seamless cultural interpretation in real time.
As plant-based dining evolves from special request to standard expectation, the ability to deliver it without compromising authenticity will distinguish serious culinary destinations from superficial imitators.
Sushi University’s vegetarian and vegan omakase is not positioned as radical reinvention. Instead, it advances a quieter proposition: the essence of omakase lies not in fish, but in trust — in the chef’s technique, in seasonality and in balance.
By returning to those foundations, Tokyo’s sushi counters may have found a way to honour tradition while accommodating the future — one carefully marinated shiitake at a time.
