The document analyzes the rise and fall of the Japanese semiconductor industry compared to Samsung. It discusses how Japan initially achieved success through technical imitation, government support, and satisfying customer demand. However, Japan later fell behind due to a lack of original technology, narrow product strategies, and failing to invest in new trends. In contrast, Samsung rose sharply by focusing on globalization, low costs, and successfully grasping market trends. The conclusions recommend Japan shift from diversification to concentration, outsource business processes, and focus on research innovation and technology development to regain competitiveness in the semiconductor industry.
