Understanding Wa – Harmony as a Social Compass

Another key concept is the distinction between uchi (inside) and soto (outside). Japanese society is highly context-sensitive, and language shifts depending on social positioning. The “inside group” includes family, close colleagues, or one’s own organisation. The “outside group” refers to clients, visitors, or external partners. This distinction influences everything from word choice to tone of voice.

“In Japan, how you speak depends on whether someone is inside or outside your group. It’s about humility, respect, and knowing your place in the relationship.”

— Hisamitsu Takai

For example, if you call a Japanese company and ask to speak to “President Yamada,” the receptionist might respond: “I’m sorry, Yamada is currently in a meeting.” In Denmark, omitting a title in that context could seem informal or even rude. But in Japan, because the receptionist and the president are part of the same uchi, it would be inappropriate to call him/her by the title “president” when talking with an external soto person. Meanwhile, the phrase “I’m sorry” isn’t personal—it’s a courteous gesture toward someone in the soto group.

Likewise, when a Japanese colleague responds to praise with “It was nothing” or “Thanks to your help,” this isn’t downplaying success. It’s a culturally expected form of modesty, aimed at maintaining social equilibrium.

These may seem like small differences—but they reflect a deeply held worldview. And for Danish leaders entering the Japanese market, they’re more than cultural curiosities. They’re a practical key to building trust, avoiding misunderstandings, and laying the groundwork for lasting partnerships.

As Hisamitsu Takai puts it: “Harmony is not just a value—it’s a way of thinking, feeling, and behaving. It runs through the logic of interaction, not just the language.”

For anyone looking to build business in Japan, understanding wa isn’t just helpful—it’s essential.

About Hisamitsu Takai

Hisamitsu Takai, Ph.D. has been a bridge between Denmark and Japan for nearly five decades. As a long-term resident of Denmark, he has played a central role in fostering cross-cultural understanding—most notably through his work at Gymnastikhøjskolen i Ollerup, where he served as the head of the board of INTAC (International Academy). There, he has helped shape international partnerships and led the creation of a Japanese-inspired garden, symbolising the deep connection between the two cultures.

Alongside his cultural work, Takai is a respected agricultural and biosystems engineer, formerly a senior scientist at Aarhus University. He is known internationally for his research on air quality and emission control in livestock housing, with over 2,500 citations across 40+ peer-reviewed publications. His later work links sustainable farming to broader global goals, including biogas innovation and the UN Sustainable Development Goals.
