Truly, Ukai. Transforming our one-of-a-kind tofu into a global delicacy.

The Keio Plaza Hotel—a landmark in Shinjuku with rich history and elegance.
On December 12, 2026 (Saturday), a new tofu-focused kaiseki restaurant, “THE UKAI TOFUYA,” will open here.

Throughout the years, Tofuya Ukai has promoted itself with the slogan “Ukai’s tofu—a world-famous specialty.” Building upon this legacy, this new restaurant aims to elevate tofu—a healthy ingredient gaining worldwide attention—into a true delicacy within the international city of Shinjuku. Drawing from Ukai’s expertise in tofu, as well as Western and Japanese culinary concepts and diverse ingredients, we will offer you entirely new flavors.

We invite you to savor a meal that nourishes both body and soul in an environment where tradition and innovation, tranquility and vibrancy seamlessly blend together.
