Domei started his own company DI CLASSE in 1990 — fulfilling his own visions of lamps characterised by nature's beauty and fragile simplicity. Mini Foresti – DI CALSSE's iconic forest lamp is the first product he worked on. Domei regards lighting not merely as a function but something beyond that. He plays with light and shadow; the kaleidoscopic shadows he creates offer a sense of therapeutic healing. His philosophy has been vastly appreciated by the Japanese audience.
Over time, his forest lamps gained a reputation overseas. As a response to the international growing demand, the company has started exhibiting at international trade fairs such as Accent on Design in New York and 'Now' at the Maison et Objet in Paris. In September 2013, his Forest lamps shone over Marie Claire Café at the Maison et Objet. Recently DI CLASSE collaborated with Oryza Design, showcasing nature-inspired lighting alongside with vibrant pop-style furniture, which created a contrasting and distinctive style.
Nature is his main theme of design. Since 2011, he has been deeply involved in an ECO project: 'earth living' which promotes sustainability. The 'earth living' is an eco product range made of recycled materials such as thinning timbers.
Aside from his role as the designer/CEO of DI CLASSE, Domei has started a new career as an artist in Melbourne, Australia. He is now creating art, along with designing products and lighting to fulfil his visions to harmonise the interiors in everyday life.
Furthermore, he has reviewed local industry from a viewpoint of Eco and challenged to produce products to activate a depopulated area. For "The Uonuma project", he has designed lighting equipment by combining the production of Japanese paper, the traditional local industry of Uonuma, and wood and metal scrap. Thanks to the magic of design, the abandoned skills and materials have turned to not only the beautiful lighting objects but reviving the local community.
