CULUMU Launches New Media '当事者発想ジャーナル' to Disseminate Co-Creation Knowledge – Inclusive Design Studio CULUMU Fully Renews Website

STYZ Inc. (Headquarters: Shibuya-ku, Tokyo, Representative Director and President: Tatsuya Tanaka), which operates the inclusive design studio 'CULUMU,' has fully renewed its website and launched a new media platform, '当事者発想ジャーナル' (Participant-Driven Journal), effective April 1, 2026.

This renewal is not merely a website refresh, but an initiative to openly share with society the 'practical know-how for creating businesses from N=1' that we have cultivated with companies and individuals. We will disseminate the value of inclusive design from multiple perspectives, providing concrete insights to all those engaged in business development and social problem-solving.

About the New Media '当事者発想ジャーナル'

<strong>About 当事者発想 (Participant-Driven Approach)</strong>

The participant-driven approach begins not by viewing a problem from the outside, but by standing in the shoes of the person in that situation, understanding their experiences, emotions, and background. It emphasizes a reciprocal co-creation perspective, building the future together with them, rather than a one-way 'doing for them' mindset. Specifically, designing from the perspective of those who have been overlooked leads to valuable solutions for many people. At its core is perceiving social issues not as 'someone else's problem' but as 'one's own concern.'

We have launched '当事者発想ジャーナル' as a platform to disseminate real insights (co-creation knowledge) gained from on-the-ground practice. We will deliver diverse content, starting with the following serial projects, to everyone involved in business development, product planning, and DE&I promotion.
