[Instructor] EY ShinNihon LLC Head of the Digital Strategy Department, Client Services Division Leader of the Space Business Support Office, Space Tech Lab Partner, Certified Public Accountant Nobuhiko Kato Senior Manager, Space Business Support Office Attorney and Certified Public Accountant Tatsu Fushimi [Key Lecture Content] The Space Strategy Fund is now widely recognized as essential for research and development in the space sector. After completing the first and second rounds of selections, the third round has begun, reaching 800 billion yen out of a total of 1 trillion yen. The utilization of satellite data has transitioned from mere demonstration to implementation in more specific fields. The space industry is on the verge of blooming, and many companies and stakeholders have begun to look toward "what comes next." In this seminar, we will analyze the trends and results of the Space Strategy Fund, discuss its future developments, and provide insights into the challenges and future prospects derived from unique experiences in planning and implementing satellite data utilization while advancing digital transformation (DX) in audit and assurance services. Experts familiar with public-private partnerships in space and the utilization of satellite data will offer suggestions to accelerate and develop your company's space business.

[Speaker] Masahiro Fukuda, Chief Analyst, Fourin Inc. [Key Lecture Content] In April 2026, Toyota will transition to a new management structure. The new president, Mr. Chiku, supported management from a financial perspective as vice president during Akio Toyoda's presidency, and later promoted the development of Woven City and Arene as CFO of Woven by Toyota. Recently, he has led capital restructuring, including the privatization of Toyota Industries, and has been responsible for the group's capital strategy. Under the new president, who comes from a financial background, Toyota is moving into a phase of harvesting the results of growth investments. Optimization of capital allocation and acceleration of decision-making are expected. This lecture will explore efforts to build a "resilient" management structure amid increasing uncertainty, focusing on five perspectives: group capital redesign, structural transformation, "SDV," "Woven City," "electrification," "product strategy," and "production technology."

We will be holding a free webinar titled "Essential Before Entering the European Business: Understanding and Addressing EU Regulations Related to Products, Packaging, and Labels." For companies exporting and selling products to Europe, compliance with EU regulations is unavoidable. However, the regulations concerning products, packaging, and labels are diverse, and many companies feel uncertain, wondering, "Where should we start checking?" and "Are we really compliant?" In this seminar, we will clearly explain the overall picture of the key EU regulations that should be organized before starting European business, as well as introduce practical points for regulatory checks that companies should implement first. This content is recommended not only for companies considering expansion into Europe but also for those already exporting to Europe who feel anxious or face challenges regarding regulatory compliance. We sincerely look forward to your participation.
