DigiRise Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director: Masahiro Chaen; our company, "DigiRise") gave a special lecture at the "27th Marketing Week - Summer 2026 - (commonly known as MaS)" hosted by RX Japan LLC.

■ Background of the presentation
With the evolution of generative AI, the way companies and individuals manage their social media accounts is changing dramatically. In particular, the discontinuation of commercial provision of the video generation AI service "Sora" has increased interest in practical issues such as "which video AI should we use in the future" and "how can we automate design work?" At "Marketing Week - Summer 2026," Japan's largest marketing-related exhibition, which featured 40 lectures over three days, our CEO, Chaen, gave a special lecture sharing practical operational know-how based on his own experience in social media management and his knowledge of AI utilization.

■ Presentation Overview
Exhibition Name: The 27th Marketing Week -Summer 2026- (Abbreviation: MaS)
Organizer: RX Japan LLC
Date: June 24th (Wednesday) – June 26th (Friday), 2026
Venue: Tokyo Big Sight West Exhibition Hall
Speaker: Masahiro Chaen, Representative Director, Digirise Co., Ltd.
Lecture Topic: "SNS Strategy After Sora's Withdrawal! Operational Techniques Using the Latest Video AI and Design Automation"

■ Key points of the lecture
In his presentation, Chaen shared the following points based on his own experience as an X (formerly Twitter) user with over 195,000 followers:

• The latest trends in generative AI: In addition to explaining the differences between ChatGPT, Claude, and Gemini models, this article explains the "third wave" of AI that can directly control PCs (such as Claude Code and Codex), which are not only responsible for drafting posts but also for executing them.
• Choosing the Right Video Generation AI: This article discusses the current state of the video AI market after Sora's withdrawal, highlighting the leading companies like ByteDance and Google, and presents a framework for selecting the appropriate tool based on your needs.
• Examples of Automated Design and Document Creation: Chaen introduces examples of automation systems that he actually uses, such as document creation, landing page production, and automated blog posting, utilizing Claude Code.
• Examples of automating social media management: This article explains specific mechanisms that significantly reduce daily operational workload, such as automatic generation of post drafts, automatic creation of YouTube video clips, and automated social media analytics reports.

■ Feedback from participants (Q&A)
During the Q&A session following the lecture, numerous specific questions were asked with a view to practical implementation, resulting in a response that exceeded the scheduled time.
Many of the questions were specific and focused on practical implementation, such as "the system for checking AI-generated content," "the learning risks of AI-generated information," and "the feasibility of integrating Claude Code with internal groupware." Chaen emphasized the importance of thorough human checks and verification, even for AI-generated content. He explained that he always checks AI-generated content with his own eyes before using or publishing it, just as he would check work assigned to his subordinates. He stressed that this approach is not limited to document creation but is also thoroughly applied to the automated posting of blog articles, and that they routinely perform fact-checks after automatic generation before publishing.

■ Comment from Representative Director Masahiro Chaen
It was a great honor to be able to speak as a special guest speaker at Marketing Week, an event that brings together many marketing professionals. I felt that many people became interested in video AI and social media management again following the news of Sora's withdrawal. Because AI is a field where tools change so rapidly, it is important to stop and continue learning at every turn. I hope that this lecture will provide participants with hints for improving their social media management and operational efficiency starting tomorrow. DigiRise will continue to disseminate practical AI utilization knowledge to both companies and individuals.
