About

Keiji Ashizawa Design is a firm that offers architecture,
interior, furniture, lighting, and product design,
capable of total design of spaces.

Keiji Ashizawa Design was founded in 2005 by Keiji Ashizawa and is based in Taito Ward, Tokyo. The studio brings together architects, interior designers, and product designers from diverse backgrounds. Guided by the philosophy of “Honest Design”, the practice is known for its craft-driven approach, rooted in material and site, and for its holistic design of spaces. Extending beyond architecture, Keiji Ashizawa Design’s expertise also encompasses landscape, interior, and furniture design, as well as branding. This multidisciplinary approach enables the studio to create unified, finely detailed environments, and has led to the successful realization of a wide range of projects both in Japan and internationally.

In addition to domestic projects in Japan, primarily in Tokyo but also from Tohoku to Kyushu, the studio is involved in a number of architecture projects overseas, in China, Vietnam, the US and the Philippines. They also work abroad with European and Asian manufacturers on furniture and products and with major domestic manufacturers in Japan. Recently projects include a hotel complex on the 45th to 47th floors of a corner hotel in Shinjuku, Tokyo, including five top-end rooms, three restaurants, a bar and a spa. Keiji Ashizawa Design was also involved in the architecture, interior and FFE of TRUNK(HOTEL) YOYOGI PARK in Tomigaya Shibuya,Tokyo.

Beyond these practices, they have been driving the Ishinomaki Laboratory furniture project, which began as a volunteer initiative to help with the recovery from the Great East Japan Earthquake, for more than ten years. The company has leapt to a further stage with the launch of ‘Ishinomaki Home Base’, a base symbolising the new Ishinomaki, and the development of the ‘Made in Local’ project, which has spread the idea of regional development to other countries around the world.

Collaboration with different industries is essential for Keiji Ashizawa Design to practise ‘Honest Design’. They work with local architects and international design firms on national and international branding projects. Examples include a housing project with Peter Stutchbury in Australia and an interior and exhibition project with atelier oï in Switzerland. In the last few years, Keiji Ashizawa Design has collaborated on several interior projects with NORM ARCHITECTS in Denmark, as well as furniture projects with Karimoku Case.
