Jojoen is a famous yakiniku restaurant founded in 1976. This time, we planned the largest flagship store of the restaurant. At the time, many foreign customers visited the restaurant in Roppongi, where the restaurant was founded, and the name of the restaurant comes from the sound of grilling meat being pronounced "jo-jo". First, we expanded the idea from the sound of grilling meat to the concept of sound, and gave the finish of materials such as Nishijin-ori, acrylic, stone, and glass a rhythmic characteristic. In addition, the piano booth is designed to have a symbolic shape that visually appeals to the spread of the sound of the performance. Inspired by the brand's history, this plan strengthens the relationship between food, space, and sound. We concept design seating that can be used for various occasions. <Solution> ・We designed concept design to take advantage of the characteristics of materials such as wood, stone, Nishijin-ori, and acrylic.・We planned seating that can accommodate a variety of occasions, including private rooms, semi-private rooms, pair seats, hall seats, and circular sofa seats. <Our project members> [Sales/Project Management] Yasuhiro Tsuruta [design, layout] RENS: Ryutaro Matsuura, Yuka Kurachi, Takuro Ishizawa [Production/ construction] Mikina Fujitaka, Kei Yokoyama, Mariko Yamamoto
