About

Our ramen is born from a singular vision: to create a dining experience that is both deeply authentic and refreshingly modern. This journey began with our founder, Hisashi, a native of Fukuoka, Japan, who sought to honour the traditional craft of Japanese ramen making—the slow-simmered dashi, the precise preparation—while integrating the clean lines and ingredient focus of Scandinavian design. This is our brand fusion: a commitment to simplicity, flavour, and community, served in an inviting space where hygge meets culinary excellence. We believe in taking complex flavours and presenting them in simple, beautiful bowls.

Hisashi's quest: From Fukuoka to the world

Hisashi was raised in Fukuoka, widely regarded as the birthplace of tonkotsu ramen. His fascination with ramen began during his university years in Japan, where he learned the foundations of the craft in a professional kitchen.

Over the years, he refined his technique and philosophy through hands-on experience, while spending more than a decade traveling across dozens of countries, immersing himself in local food cultures and studying how people express identity through food.

His journeys back to Japan became pilgrimages—visiting remote shops to study and absorb the craft at its source.

Ku-Kai Ramen belongs to the tradition of Kyushu ramen, defined by thin noodles and a deeply refined tonkotsu broth. Each bowl is made with complete dedication, filled with the essence of authentic tonkotsu ramen, while naturally resonating with Danish food culture.

After years of dedication and passion, Ku-Kai Ramen is the realisation of that lifelong commitment—bringing the soul of authentic Japanese ramen, made from scratch, to Copenhagen.

The Focus: Simplicity, flavour, and quality

Ku-Kai Ramen is a brand built on a deliberate fusion. Authentic Japanese technique meets Scandinavian clarity. We spend days simmering our Tonkotsu to achieve its signature depth. We innovate with our fully house-made Vegan Shoyu and revolutionary Vegan Tantanmen—a complex, creamy, and spicy experience not seen before in Copenhagen. Our focus is clear: to honour tradition while elevating the dining experience with modern standards of quality and design.

The Slurp & Go Experience

We are a small, dedicated ramen shop with only 10 counter seats. Because of our size, we are 100% walk-in only – no reservations.

Grab a seat, enjoy a steaming bowl of Tonkotsu, and soak in the vibe. Turnaround is fast, so even if there’s a wait, your bowl is never far away.

Since our hours can vary depending on our broth prep, we recommend checking our Instagram for today’s live status before heading out.

Planning a private KuKai slurp? You can still book the entire shop for your private event! Contact us for details.
