[About Nadaman Co., Ltd., Operator of 'Nadaman']

Nadaman's history dates back to 1830 (Tenpo 1), when the first-generation Takeru Nada founded a restaurant in Osaka that would become the foundation of the ryotei 'Nadaman.' In 1919 (Taisho 8), the third-generation Takeru Nada traveled to Europe as a personal chef accompanying Prince Saionji Kimmochi to the Paris Peace Conference. In 1986 (Showa 61), the official banquet for the Tokyo Summit was held at 'Nadaman Honten Sazanka-so,' marking the first time a private facility hosted such an event. In 2005 (Heisei 17), Nadaman represented Japanese cuisine at the Aichi Expo. Today, the company operates 30 restaurants across three countries and 44 shops selling bento and prepared meals. For over 190 years—from the Tenpo era to the Reiwa era—Nadaman has preserved the traditions of Japanese cuisine while evolving with the times and customer preferences, earning enduring loyalty as a historic Japanese restaurant both in Japan and abroad.
