Hello, my name is Nobuko Matsuzaka, the owner of Chōkatsu OKAMI LABO. After graduating from university in Tokyo, I worked for five years as a home economics teacher. In 1996, I got married to a third-generation owner of a restaurant, and together we ran the restaurant as the okami (proprietress) for 20 years.
In 2019, I moved to Kyoto to work as a restaurant manager in a newly built hotel, and then in 2023, I became independent and opened Chōkatsu OKAMI LABO.
Previously, while running our restaurant in Ginza, Tokyo, I also operated a bar called OKAMI Bar. However, due to my inexperience, the bar struggled and eventually closed. I established OKAMI LABO to turn my past setback into a new opportunity. I firmly believe that gut health (chōkatsu) is something essential for the times ahead, which is why I chose the name Chōkatsu OKAMI LABO. We opened in April 2023, and it has now been 2 years and 6 months.

The concept is gut health (chōkatsu), so I focus on creating food that is good and gentle on the intestines. I aim for the kind of meals traditionally eaten in Japanese households by using fresh, seasonal vegetables from Kyoto, fiber-rich ingredients, and homemade fermented foods.
I also make sure to serve warm dishes that stay warm and cold dishes that stay cold.

I cater to everyone!
We want our restaurant to be a place where people can relax, enjoy delicious food, and even connect with fellow diners sitting next to them. In many ways, we want to create a space where people can eat happily and enjoyably.

For desserts, I mainly make gluten-free items.
For drinks, we offer homemade fermented beverages, smoothies, and even alcohol.

At first, people around me strongly opposed using intestines as the logo.
But I loved the design for its rock-and-punk vibe and its full of character, so I insisted on it.
As for the name, since I had long worked as an okami (proprietress), I used “OKAMI,” the same as in my previous OKAMI Bar. The meaning behind Chōkatsu OKAMI LABO is a place where the okami researches gut health.
Through our meals, I want our customers to become healthier from the inside out.

The core concept of Chōkatsu OKAMI LABO is:
Both are essential for guiding the intestines toward good health.
While women make up the majority of clients, men are also welcome to make a reservation.

For fish, I like simmered dishes made with homemade pickled plums.
For meat, I enjoy a dish where vegetables and meat are combined with nam pla, a fermented fish sauce, eaten almost like a salad.
