About the Yamaguchi Marutai Festival

The event caters to professionals within the painting and automotive sectors, showcasing a variety of products including brushes, rollers, painting equipment, waterproof materials, and auto body products. Attendees will have the chance to purchase tools and equipment at special festival prices, making it a key occasion for networking and business discussions within the industry.

Industry Background and Challenges

As artificial intelligence and technology become more prevalent in designing and estimating costs in the construction industry, traditional skills inherent to physical tasks, like painting, remain rooted in human experience and judgment. Experts can instantly assess surface conditions, adjust techniques based on environmental factors like temperature and humidity, and balance safety and quality — all of which significantly depend on years of practical experience.

While Japan's construction industry sees over 30% of its workforce aged 55 and older, young workers make up a mere 10%. This demographic imbalance poses a structural challenge as veteran workers retire and fewer young craftsmen enter the field. Consequently, the lack of sufficient mentors leads to a decline in practical training.

Moreover, numerous skills remain as tacit knowledge within the workplace, contributing to inefficiencies in training. A lack of systematic education regarding important decision-making processes leads to:

- Increased burdens on trainers
- Varied growth rates among younger employees
- Complications in training foreign workers
- Decreased reproducibility of quality
- Increased risk of mistakes and accidents.

As operational efficiency brought by AI grows, so does the importance of mastering physical skills in the workforce. The challenge to transfer these skills has evolved from merely development issues into critical business strategies that can determine a company's competitive edge, thus prompting a need for "Skills Succession DX."

Kashisuto®️: Revolutionizing Craftsman Education

Kashisuto®️ began as a solution within the painting industry, recognizing that the quality of work directly correlates to the craftsmen’s skill set. Even when using the same materials, results can vary significantly based on individual judgment and sensory cues cultivated over years.

Craftsmen traditionally rely on:

- Specific audio cues for decision-making
- Pressure applied through tools
- Timing for adjustments
- Understanding of acceptable limits

These nuanced judgments derive predominantly from experience, with rarely any formalized training. Kashisuto seeks to articulate and structure these "invisible judgments,” allowing for reproducible training materials.

Through a patented "skill extraction" technique, Kashisuto observes seasoned craftsmen's movements, observations, and decision-making processes, successfully translating these elements into structured educational resources. This not only records steps but visualizes the underlying logic of craftsmanship, transforming it into a viable asset for education.

As part of its exhibition at the Yamaguchi Marutai Festival, Kashisuto aims to present these proven methods to industry professionals, demonstrating their practical implications firsthand.

Conclusion

Kashisuto, represented by its CEO, Ryohei Yoshimatsu, sees the festival as a pivotal opportunity to showcase effective training methods and gather real-time feedback from industry stakeholders. By addressing skills succession issues head-on within the construction sector alongside AI advancements, Kashisuto not only seeks to enhance craftsmanship but also profoundly impact workforce training methods nationwide.
