The project is located in the Hakata terminal building, a historic gateway for international exchange and a major multimodal hub. The spatial composition centers on serving local seafood in Donburi as a medium to communicate the city's cultural context. Traditional crafts, materials, and artisanal techniques are deliberately integrated with lighting as parallel elements, forming a framework of depth and calmness. Shadow reveals material depth. The design articulates the relationship between space and food, redefining everyday dining as a cultural interface grounded in Japanese sensibility.

Production Technology
The design emphasizes regional identity through material expression and artisanal techniques. A dark plaster wall mixed with local earth and charcoal is hand-applied, its tonal variations abstractly referencing waves of the Genkai Sea. Recessed red display shelves incorporate Hakata-ori textile, while wood panels and furnishings with pronounced natural grain evoke surrounding forests. Controlled lighting and material composition guide visual focus and spatial depth. Individually directed lighting enhances each dish while creating quiet personal space. The project was realized through close collaboration with local artisans, integrating traditional craft with contemporary spatial design.
Design Challenge
The main challenge was transforming a compact commercial space in a busy station into a high-performing environment that balanced cultural storytelling with customer appeal. Internally, culinary, spatial, and regional narratives had to be unified into a seamless experience. Externally, constraints of the new terminal building, strict fire codes, mechanical limits, and tight construction schedules posed challenges. Integrating original menu concepts and craft displays without crowding the space required careful zoning, sequencing, and coordination with stakeholders to ensure both functionality and emotional impact.
Project Duration
The project commenced in January 2010 and was completed in March 2011 in Hakata, Fukuoka Prefecture, Japan.
Operation Flow
The space offers multiple ways for visitors to enjoy their time. Counter seats allow solo diners to watch chefs at work while savoring fresh, quick meals. Window seats provide serene sea views, and small tables are perfect for sharing dishes with friends. The menu encourages a smooth dining flow, starting with seafood bowls that can be elegantly turned into ochazuke. A curated display of local crafts and preserved foods adds cultural allure and invites gentle exploration. The layout ensures each visit feels both personal and seamless.
Research
Type of Research: Applied design research. Research Objective: To articulate Hakata's identity through spatial and culinary design. Methodology: Contextual and collaborative field research and iterative development. Data Collection: Site visits, interviews with artisans and chefs, and material mockups. Participants: Design team, owner, craftspeople, chefs. Results: Integrated spatial experience linking food and craft. Insights: Evidence based sensory design communicates cultural value. Effect: Cultural engagement and business performance.
Inspiration
The project is inspired by the cultural and geographical characteristics of Hakata, a city surrounded by sea and forest and historically a Japanese gateway connected to the Silk Road. The design interprets this context through traditional colors, textures, crafts, and regional materials to construct a spatial experience of local culture. It presents and sells local crafts and processed foods while integrating regional food culture, where a fresh Seafood Donburi transforms into Ochazuke, creating a layered experience. It aims to provide travelers with a brief yet immersive encounter with local culture and relaxation at the main terminal.
