How business is done in Japan
Population
About 124 million (2024), down from a peak around 128 million in 2008 and declining about 0.4 to 0.5% a year. It has one of the world's oldest populations (nearly 30% over 65), a very low birthrate and minimal immigration, concentrated around Tokyo, Osaka and Nagoya.
Language(s) spoken
Japanese is effectively universal and central to business; general English proficiency is limited, so localization is essential, not optional. Regional dialects exist (such as Kansai-ben), and the Ryukyuan languages of Okinawa are endangered — but they do not affect commercial language choice.
How business decisions are made
Deeply consensus-driven and relationship-based. Informal pre-alignment (nemawashi) precedes formal circulated approval (ringi), so decisions are slow but, once made, firmly backed. Buyers are risk-averse and prize reliability and long-term trust over price, and incumbents are very hard to unseat. References, patience and precision matter far more than aggressive pitching.
Effective marketing
Credibility, detail, politeness and quality cues build trust; overt or exaggerated claims backfire. Buyers want proof and references, and seasonality is central — cherry-blossom spring, New Year, and the ochugen (summer) and oseibo (winter) gift-giving seasons. Thorough localization, not just translation, is expected.
Similar countries
The closest regional parallels are South Korea and Taiwan (hierarchy, relationship emphasis, quality focus), though Japan is distinctive enough that it is usually best treated as its own segment.
