What It Is

KOTOK（コトック株式会社） is a Japanese product design and design consulting company founded in 2013 by designer Hiroshi Yasutomi after he left Sony Design Center. The website emphasizes “コトのデザイン、モノのデザイン、ヒトとデザイン” — design not only for product form, but also for user experience, behavior, and relationships between people. Its positioning is closer to a high-end product design consultancy than a standardized online design tool.

Core Capabilities and Service Types

Based on the site content, KOTOK’s core work is product design consulting, with a particular strength in reorganizing a company’s existing advanced technologies and resources into “new experiences.” The founder worked at Sony on consumer electronics such as Walkman, headphones, Handycam, and camera lenses, and also participated in product development from a UX perspective within R&D. One case study mentions designing an active speaker for Roland DG’s 3D printer and 3D milling machine promotion project. Rather than simply creating a styling mockup, the team built a functional product that could actually produce sound, demonstrating the manufacturing experience enabled by the equipment.

Pricing, Licensing, and Collaboration

The website does not disclose pricing, billing methods, project timelines, payment methods, copyright ownership of design deliverables, licensing scope, or delivery file formats. For buyers, key commercial terms therefore need to be discussed and confirmed directly. In terms of collaboration, the content only indicates that KOTOK accepts corporate commissions and has substantial experience working on new business initiatives and with startups. It does not specify whether remote collaboration is supported, which project management tools are used, or whether the company has a multidisciplinary team.

Pros and Cons

KOTOK’s main strengths are the founder’s solid background, long-term product design experience at Sony, and multiple awards including the IF Design Award, Red Dot Design Award, and Good Design Award. Its methodology also emphasizes the combination of concept development, experience design, and technical implementation, making it suitable for technology-driven hardware products. The limitations are that the website provides relatively little information, with no clear service packages, pricing, process, copyright terms, or team size details, which makes it less transparent for first-time clients.

Who It’s For and Access from China

KOTOK is better suited to companies and startups with needs in hardware innovation, consumer electronics, technology demonstration prototypes, or new product concept definition — especially projects that aim to turn technology into experiences users can clearly perceive. Access from China cannot be determined from the available content and is marked as unknown; payment methods are also not disclosed. For local alternatives in China, industrial design consultancies such as 洛可可, 浪尖设计, and YANG DESIGN may be considered.
