METREA Inc. (Headquarters: Shinjuku-ku, Tokyo; CEO: Marika Hirata), whose mission is to “continue to weave heart-stirring beauty and stories,” is pleased to announce that it has conducted specialized AI training for the creative department of Tohokushinsha Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Keiichi Kosaka). This training was part of METREA’s core business, “AI Reskilling Training,” which supports the in-house development of AI production know-how. Background and challenges of training implementation In recent years, many companies have been implementing general-purpose AI, such as ChatGPT and Gemini, in-house as a tool to improve business efficiency. Meanwhile, the use of AI has also been attracting attention in more specialized “creative department” tasks, such as video production and design. However, in many creative fields, the demands of daily work have made it difficult to keep up with the rapidly evolving trends in the latest creative AI tools and the know-how needed to apply them in practice. About METREA’s “AI Reskilling Training” METREA’s AI Reskilling Training is more than just learning how to use tools. METREA’s goal is to systematize the “advanced production know-how using AI” it has cultivated in cutting-edge contract production work, tailored to each company’s challenges, and “instill this knowledge within the company and support in-house production.” For this training session for Tohokushinsha, METREA’s top creators served as instructors, providing a practical curriculum tailored to the challenges faced in the field. Training Key Points This training aimed to help participants acquire the latest creative AI technologies through the following practical curriculum. • Opening: Introduce the instructor, share their achievements, and share the training goals. • Image Generation Section: Practice Midjourney • We learned practically everything from the basics of Midjourney prompts to how to improve the style or feel when it differs from what we expected, how to correct composition, poses, and facial
expressions, and how to utilize various parameters. • Video Generation Section: Learned the features and usage of major video generation AI tools, including Runway Gen-4, Kling AI, and Google Veo 3, as well as the basic principles of effective prompt design. • Music Generation Section: Practice SUNO • We learned practical skills for music generation AI, such as reference collection techniques using SUNO, style prompting, designing consistency between lyrics and melody, instrument and arrangement design, and the persona method. • Image Generation Section (Advanced): Practical Stable Diffusion • We learned how to build AI models in a local environment using Stable Diffusion and how to create highly artistic visual expressions. • Q&A • A question-and-answer session was held to answer any questions that arose throughout the training and to address any challenges
participants may have in using AI in their own work. Participant’s voice • “It was so much fun! I’ve used AI a few times in VCon, but I was still feeling my way around writing prompts and using the finer details of mid-journey, so I’m glad I got to learn!” • “I was having trouble maintaining consistency in the people I was generating images for, so I was really grateful for the information you shared about the features and methods for achieving consistency. Thank you so much.” • “I really learned the basic principles of how to create a prompt. The sref code was interesting, and I’ll explore it further. I haven’t tried video generation yet, so I’ll try out what I learned today.” Company Profile About Tohokushinsha Co., Ltd. Company name:
