[Speaker] Innovation Analyst Andy Kondo [Key Lecture Content] *The latest content will be added as appropriate based on on-site research at CES. The following may change depending on the event status.* CES has now become "the world's largest mobility exhibition," comparable to an auto show. The focus for 2026 will be on the social implementation of autonomous driving, the rise of Software-Defined Vehicles (SDV), the proliferation of AI-equipped vehicles, and the rapid growth of Chinese OEMs, all of which are converging to rewrite the industrial structure. In this lecture, from the perspective of an analyst who has been on-site for over 10 years, we will interpret where the global mobility industry is headed based on the "real scene of CES 2026." Furthermore, we will discuss how these changes will impact and create opportunities in the Japanese market, which is finally beginning to embrace electrification, while aligning with the latest international trends.
