[Project Summary] A renewal project for the JAL lounge at New Chitose Airport's domestic terminal. Based on the concept of "Japanese appearance," we incorporated the texture of Japanese materials and the color of materials that evoke the corporate color red, and concept design the Sakura Lounge and the Diamond Premier Lounge, the highest-class lounge for domestic flights, as open, high-quality, and sophisticated spaces. The seating layout is designed to be functional and have a wide variety of seats for various occasions. [Customer's Challenge] The major challenge was to concretely express the JAL brand keyword "sophistication" and to differentiate it from the Haneda JAL International Lounge (NOMURA AND concept design). In addition, we were considering how to express the individuality of each airport when expanding to each major airport (about 5 airports) in the future, and in terms of functionality, the challenge was to secure the number of seats calculated from the total square meters and expand the baggage storage function. [Solution] In terms of differentiation, the international flights were based on white wood, but for this domestic flight, we differentiated it as concept design that focuses on the brand by expressing the corporate color "red" with various materials. To express sophistication, we used sharp textures such as glass and metalwork, and incorporated cutting-edge art to create a highly sensitive space. We achieved the expansion of storage functions by designing custom-made furniture that ensures storage space. <Our project members> [Sales/Project Management] Hisayasu Takenaka [Direction] Ryu Kosaka [design, layout] Hironori Takeuchi
