What 株式会社SANKO does

KAYAC SANKO (株式会社KAYAC SANKO) is a Tokyo-based communication design agency founded on April 14, 1965, and operated today as a related company of publicly-listed KAYAC Inc. (株式会社カヤック) under Representative Director Michio Uno. The firm delivers integrated communication services organized around three core pillars: Branding (organizational development, CI/logo design, inner branding, recruitment branding, and product-development design), Digital Marketing (SNS strategy and operations, web advertising, and SEO/MEO), and Sales Promotion (website production, video production, graphic design, and campaign and event planning). A proprietary sub-brand, 're:com' (リーコム), extends the offering into organizational transformation and inner/outer branding packaged as a 'communication doctor' service, and a dedicated '入試広報戦略LABO' (nyushikoho.com) practice serves Japanese educational institutions with enrollment marketing.

The company's client base is concentrated in Japan and spans large and mid-sized enterprises, government agencies, and educational institutions across more than nine industries, including housing (Sumitomo Forestry), gaming hardware (Mouse Computer), consumer goods (Kai Corporation, Pentel, Otsuka Foods), real estate and commercial facilities (Mitsubishi Estate), food delivery (Captain Foods), steel technology (Fuji Protec), and tourism (Tokyo Tourism Foundation), as well as the Tokyo Metropolitan Government Welfare Bureau and multiple universities and vocational schools. Revenue is generated through project-based professional services engagements with quote-based pricing under a sales-led go-to-market motion; no recurring subscription or platform revenue is disclosed. The firm operates the philosophy of '三方よし' (three-way goodness) and '共進化' (co-evolution) with clients, partners, and society.

KAYAC SANKO is a private company headquartered in Kanda, Tokyo (relocated in June 2021), with stated capital of ¥30 million and no disclosed revenue, headcount, funding, or M&A activity in the source material. The firm operates exclusively in the Japanese domestic market, primarily the Kanto region, and maintains a related-company (not parent-subsidiary) affiliation with KAYAC Inc., a separate publicly-listed creative company.
