TUCUSI
“Eat fully. Drink fully. Live fully.”
We offer natural wines and authentic dishes in a space where guests can relax without pretension.
A glass-walled, open and airy dining room.
A terrace that blends seamlessly into the city.
An interior that balances sophistication with warmth.
Some guests stop by alone for a quiet moment.
Others gather with friends to share conversation late into the night.
TUCUSI lives in that gentle space between the everyday and the extraordinary.
We honor the stories behind our ingredients, the character of each wine,
and the connections formed between people at the table.
And we will continue to create those moments—
moments where food, people, and place resonate as one.

Maison Gyoza by Tucusi
Maison Gyoza by Tucusi is a new gyoza and casual dining project created by Tucusi.
Our small handmade gyoza are carefully wrapped in-house every day, grilled until perfectly crispy on the outside while remaining juicy inside. From our classic garlic gyoza to our refreshing ginger gyoza, each dish is simple yet thoughtfully balanced in flavor.
Enjoy our gyoza with beer, highballs, and casual drinks in a relaxed atmosphere designed for everyday dining and gathering.
Inspired by the warm and welcoming spirit cultivated at Tucusi, Maison Gyoza aims to create a more casual, approachable space where people, food, and the city naturally connect.

Catering Services
We bring the sensibility of TUCUSI directly to corporate events, parties, film shoots, and more—
delivering food experiences that truly resonate.
Based in Kansai, we offer on-site cooking, wine pairing, and spatial styling for a variety of occasions.
We are also planning to expand our services to Tokyo and the greater Kanto area.
New Ventures & Projects
We develop projects that connect culture, design, and local communities—
all through the lens of food.
Leveraging our domestic and international networks,
we bring new possibilities to life through restaurant development,
food processing and manufacturing, product design, and retail initiatives.
Working closely with local producers, artisans, and creators,
we aim to build a sustainable ecosystem that links
those who make with those who enjoy food.
Looking ahead, we plan to expand globally—particularly across Asia—
establishing hubs that bridge local traditions with global food culture.
