Another Sendai Experience in Azabu-Juban: Gyutan Keyaki Launches 'Zunda Shake'

Gyutan Keyaki, a beef tongue restaurant operated by BLOOM Co., Ltd., which runs eateries across eastern Japan, will launch the 'Zunda Shake' exclusively at its Azabu-Juban branch on Saturday, May 23, 2026. The drink is a reinterpretation of Miyagi's traditional 'zunda' (edamame paste).

The product was developed by an expert team from Zunda Lab, who aim to make zunda a nationwide staple. Leveraging knowledge from pastry chefs, nurses, and pharmacists, they have created a drink that is both delicious and healthy.

Azabujuban is historically linked to Sendai, having once housed a lower residence of the Sendai Domain. This launch marks the third phase of the company's regional co-creation project, offering 'another Sendai experience' following its beef tongue dishes.

The 'Zunda Shake' was developed by a team of professionals, including pastry chefs, nurses, pharmacists, cooks, and registered dietitians. The shake contains no colorings or preservatives and stays true to the authentic taste enjoyed in Miyagi Prefecture for generations. It is made only with salted edamame and sugar, using traditional methods. While maintaining the distinct texture of zunda, it is blended into a smooth paste.

The shake is designed to pair well with beef tongue, offering a light aftertaste that can be enjoyed during or after a meal without feeling heavy.
