Business Details

In addition to manufacturing and selling pyrotechnics (training, life-saving, defense equipment, etc.), the segment provides high-energy materials evaluation testing and combustion disposal services. Major customers are the Ministry of Defense (approximately 51% of sales in FY2026 (ending March 2026)) and MinebeaMitsumi Inc. (approximately 14%). While the defense field continues to see a trend of increased production, some products have seen procurement discontinued; however, rising demand for combustion disposal services from both public and private sectors drove revenue growth.

Recent Overview

Sales to the Ministry of Defense increased 18% year on year; higher combustion disposal demand drove revenue and profit growth

In FY2026 (ending March 2026), sales in the Pyrotechnics Business were ¥1,960 million (up 5.1% year on year), and segment profit was ¥220 million (up 3.6% year on year). Sales to the Ministry of Defense increased significantly from ¥923 million to ¥1,089 million, while sales to MinebeaMitsumi Inc. decreased from ¥327 million to ¥296 million. Solid demand for combustion disposal services from both public and private sectors drove revenue growth. Capital expenditure in the current period was restrained due to a rebound effect following substantial facility and equipment renewals in the prior period, though investment in factory infrastructure improvements and combustion disposal facility renovations continued. Rising raw material costs and energy prices partially pressured profitability.

Key Products

Manufacturing and sales of pyrotechnics with the Ministry of Defense as the primary customer. Sales to the Ministry of Defense in FY2026 (ending March 2026) were ¥1,089 million (up 18.0% year on year).

service
High-Energy Materials Evaluation Testing

A service that undertakes contracted evaluation testing of high-energy materials in response to inquiries from private companies, research institutions, and others. R&D expenses increased to ¥13 million in FY2026 (ending March 2026) (up 35.5% year on year), reflecting continued investment in technology development.

service
Combustion Disposal Services

A business that undertakes contracted combustion disposal of used and unneeded pyrotechnics from both public and private sector clients. Orders remained solid in FY2026 (ending March 2026), becoming a major factor in revenue growth. Investment in the renovation of combustion disposal facilities also continued.

Growth Drivers

  • Increased orders for defense equipment driven by defense policy trends (sales to the Ministry of Defense rose 18.0% year on year to ¥1,089 million)
  • Rising demand for combustion disposal of used pyrotechnics from both public and private sectors (expected to continue for the time being)
  • Expansion of contracted high-energy materials evaluation testing (increased inquiries from private companies and research institutions)
  • Increased R&D expenses (up 35.5% year on year to ¥13 million) supporting efforts to deliver new value from high-energy materials and expand the market
  • Reduced capital expenditure burden and improved profitability going forward following the completion of large-scale facility renewals in the prior period

Risks

  • Uncertainty in sales due to a mix of increased and decreased procurement across individual defense equipment products (risk of procurement discontinuation for certain products)
  • Customer concentration risk due to high sales concentration with the Ministry of Defense (approximately 51% of sales in FY2026 (ending March 2026))
  • Risk of parts shortages due to difficulty in sourcing raw materials and withdrawal of processing contractors (stable procurement remains challenging)
  • Risk of cost increases pressuring profitability due to rising raw material costs and energy prices
  • Risk of concentration and subsequent decline in spot orders (combustion disposal and evaluation testing projects)
  • Risk of increased fixed costs from continued capital investment in factory infrastructure improvements and combustion disposal facility renovations
  • Risk of skewed production planning and reduced profitability due to high-mix, low-volume production and concentrated delivery deadlines
