DAIKEN generates revenue through B2B sales of building materials to architects, designers, contractors, and carpenters via the D-TAIL professional member portal, B2C sales through a network of 10 company-owned showrooms across Japan (Sapporo, Sendai, Kanazawa, Shinjuku, Akihabara Sound, Nagoya, Osaka, Hiroshima, Takamatsu, Fukuoka), direct e-commerce via DAIKEN WEB SHOP, and project-based renovation contracting through its ReformQ subsidiary in the Tokyo metropolitan area.

The customer base spans individual homeowners undertaking new construction or renovation, commercial and public-facility developers (healthcare, education, hospitality, offices), and professional specifiers. Pricing is quote-based with self-service digital tools (web quotation system, storage planning software, AR/space simulation) supporting pre-purchase configuration.
