What is "B Corp™"?
"B Corp™ (hereafter B Corp)" is a certification system operated by B Lab, a U.S. nonprofit organization, that certifies "good companies" that consider the environment and society. As of May 2026, more than 10,000 companies across 104 countries worldwide—and 84 companies in Japan—have obtained the certification, and the number continues to grow.
To obtain the certification, a company must use a tool called the "B Impact Assessment," which evaluates, benchmarks, and helps improve its social and environmental performance, by answering a wide range of questions. Companies are assessed against more than 200 criteria spanning five sections—"Governance," "Workers," "Community," "Environment," and "Customers"—and by earning a score of 80 or higher, they are recognized as companies aiming for a sustainable future through their business (*the standards transitioned to a new framework in March 2026).
B Corp is not merely a certification system; it is also an international movement that reframes business as "a force for making society better" and works to expand that practice. Obtaining the certification is also an expression of the intention to help create and advance this current together.
ZUKAI Inc. and B Corp
Ever since we learned of B Corp's existence in 2017, ZUKAI Inc. has continued to resonate with its philosophy.
The question "What is a good company?"—which can easily become vague and confined to individual intuition—can be structured into multiple categories and various indicators, creating a foundation on which companies and consumers around the world can discuss it in a shared language. We feel this is exactly the same in nature as what ZUKAI Inc. works on every day: "reading and interpreting complex information and mechanisms, and turning them into diagrams anyone can handle."
ZUKAI Inc.'s purpose is "to bring people and society closer through diagrams." We want to systematize knowledge that is hard to access due to specialization or division, and create a shared language that encourages social dialogue and action. The motivation behind aiming for B Corp certification was our desire to implement this social impact model not only in our external activities but in the management of our own company itself.
Going Forward
B Corp certification is a framework that requires reassessment every three years and is constantly being updated. This certification is not a destination but merely a starting point. We will continue to question our own impact, make ongoing improvements, and keep circulating a shared language built through diagrams into society.

▼ ZUKAI Inc. Company Description
ZUKAI Inc. is a visual think tank that reads and interprets complex information and mechanisms and turns them into diagrams anyone can handle. We discern knowledge that is hard to access due to specialization or division from its structure, systematize it, and create a shared language that encourages social dialogue and action.
We develop original frameworks such as Bizgram, the Purpose Model, and The Map of Accounting in collaboration with experts, and deliver them to society through training, consulting, digital products, and more. We value circulating the knowledge we create widely as a public good—for example, by publishing the full text of our books online before they go on sale.
Since our founding in 2018, under the purpose of "bringing people and society closer through diagrams," we have continued our activities aiming for a state in which diverse people can fairly participate in society and co-create together.
