This area was reclaimed during the Edo period as part of the castle town development led by Tokugawa Ieyasu. It became a samurai district lined with the residences of feudal lords overlooking Edo Castle. Traces of this history remain today in legends such as the Kabutozuka mound, said to be the origin of the name Kabutocho, and the historic Yoroi Ferry Crossing.

With the Meiji Restoration, the foundations of Japan's modern economy were established here, centered around Eiichi Shibusawa, who built his residence in the district. The area developed into Japan's financial center with the establishment of institutions such as the First National Bank, Japan's first modern bank, and the Tokyo Stock Exchange.

It is within this historically significant setting of Nihonbashi Kabutocho that TYNK, a caffeine-free craft tea brand inspired by the wisdom of traditional Japanese herbal medicine, opened its first flagship store.

Committed to quality from the very source of its ingredients, TYNK operates its own pesticide-free farm in Nobeoka, Miyazaki Prefecture. Moving beyond the common perception that caffeine-free beverages lack flavor or that herbal remedies are difficult to drink, the brand pursues blends with a taste that people can enjoy every day.

Reflecting this philosophy, the spatial design avoids relying on excessive decoration or rare materials. Instead, much like herbal medicine works through the careful combination of ingredients, the design employs simple and universal materials, seeking to achieve the greatest effect through the minimum of intervention.

Existing architectural elements were preserved wherever possible and treated on equal terms with newly introduced components. Through this approach, the space aims to create a natural coexistence between old and new. This coexistence mirrors the evolving landscape of Kabutocho itself, a place where layers of history from the Edo period through the Meiji era and into the present day continue to overlap and thrive.
