Overview of Participation

Levain Community, a subsidiary of MIRARTH Holdings, recently participated in the 24th SMART ENERGY WEEK, held from September 17 to 19, 2025, at Makuhari Messe. They collaborated with Mitsui Sumitomo Insurance to showcase state-of-the-art technology aimed at addressing modern challenges within the solar energy sector, especially concerning cable theft and security.

Event Highlights

The event attracted a total of 45,741 visitors over three days, marking an increase of 6,119 attendees from the previous year. In addition to exhibiting, the joint booth welcomed over 500 visitors, where attendees engaged in discussions regarding cable theft prevention solutions and AI-powered smart cameras specifically designed for solar energy applications.

The immediate response following the press release in April about this solution has been overwhelmingly positive. Numerous inquiries arose from Mitsui Sumitomo’s insurance agents, as well as operators in the renewable energy sector, demonstrating a significant market interest in enhancing security measures at solar power plants. Levain Community has begun to systematically introduce this solution to stakeholders, emphasizing its essential role in reducing theft incidents, which have been increasing in recent years.

Strategic Objectives

Both Levain Community and Mitsui Sumitomo Insurance share a vision of decreasing solar power station theft incidents through advanced technological solutions. Their collaborative efforts are not merely about protecting assets but also about promoting greater adoption of solar energy within Japan. This initiative aligns with their commitment to support a carbon-neutral society, contributing to the broader environmental goals outlined in Japan's policies.
