For decades, Japan developed technology in a vacuum. The domestic market was so profitable that export wasn't necessary. This led to the dominance of physical media (Blu-rays costing $60 per two episodes) and rental stores (Tsutaya). The industry fought digital downloads and streaming for years to protect physical sales and rental revenue.
Japan’s entertainment industry is fueled by vertical integration and a reluctance to embrace disruptive streaming models—until recently.
Paradoxically, while K-pop (Korean) aggressively Westernizes (English lyrics, global auditions), J-entertainment remains stubbornly domestic. Sony Music Japan’s biggest acts rarely sing in English. Japanese game developers (Nintendo, FromSoftware) prioritize gameplay systems over cinematic narrative.
This is sakoku (closed country) 2.0—not isolationism, but confidence that local taste is superior. It works because the domestic market (120 million wealthy consumers) is large enough to ignore global trends. Yet, when they do export (Demon Slayer, Elden Ring), they dominate by refusing to dilute their Japaneseness.
