When I first arrived in Tokyo to work with Tanaka-san’s team, I thought being on time meant arriving exactly at the scheduled time. During my first meeting, I walked in right at 9:00 AM, only to find everyone else had been there for fifteen minutes. Tanaka-san smiled politely, but I could feel I had made my first cultural misstep. Over the next few months, I learned that maintaining wa – the group harmony – was at the heart of everything. During one important project discussion, I directly disagreed with Yamamoto-san’s proposal in front of the team. The sudden silence in the room taught me more than any handbook could. My senpai (senior colleague) later explained that such direct confrontation disrupted the group’s harmony. I soon discovered that understanding tatemae (what people say publicly) and honne (what they truly think) was crucial. When Tanaka-san said ‘We will consider your proposal carefully,’ it often meant ‘no.’ Learning to read between the lines took time, but it helped me avoid many misunderstandings. The turning point came during an evening at a traditional restaurant with Yamamoto-san. As my business partner, he had seemed distant during office meetings. But sharing meals, participating in after-work gatherings, and learning the proper way to exchange meishi (business cards) gradually built trust. My biggest success came when I learned about nemawashi – the process of quietly building consensus before formal meetings. Instead of presenting ideas directly in meetings, I started having informal conversations with key team members beforehand. This approach helped me understand the importance of hierarchy and respect between senpai and kohai (senior and junior colleagues). After a year, I finally understood that success in Japanese business culture wasn’t just about what you do – it’s about how you do it. Building relationships, showing respect for hierarchy, and maintaining group harmony became natural parts of my work style. When Tanaka-san invited me to meet his family, I knew I had truly begun to understand the culture.
