Business Details

Centered on Taiyo Nippon Sanso Corporation, the segment provides a wide range of products and services including Separate Gases such as oxygen, nitrogen, and argon, Specialty Gases such as carbon dioxide, helium, and hydrogen, electronic materials gases, LP Gas, medical gases, Gas-Related Equipment & Construction, and compound semiconductor manufacturing equipment. It serves diverse industrial customers in steel, chemicals, electronics, medical, and other sectors, delivering integrated solutions domestically from manufacturing through sales and facility maintenance.

Recent Overview

Despite lower revenue, profit margin improved significantly due to price management and increased electronics construction revenue

In the Japan segment for FY2026 (ending March 2026), revenue from external customers decreased to ¥406,296 million (down 0.9% year on year) due to declining shipment volumes of Separate Gases and LP Gas, and weak industrial gas-related equipment and construction. On the other hand, price management effects on carbon dioxide, packaged gases, and electronic materials gases, along with increased revenue from progress on medium- to large-scale electronics-related construction projects, contributed to a significant increase in segment profit to ¥54,182 million (up 15.1% year on year). The core operating profit margin improved from 11.0% to 12.7%.

Key Products

product
Industrial Gases (Separate Gases)

Oxygen, nitrogen, and argon produced by air separation units are supplied to major industries, with diverse supply formats including On-Site, bulk, and cylinder delivery. In the current period, shipment volumes declined, contributing to lower revenue.

product
Specialty Gases & Electronic Materials Gases

Provides carbon dioxide, helium, hydrogen, acetylene, and electronic materials gases (pure gases, etc.). In the current period, price management effects on carbon dioxide, packaged gases, and electronic materials gases contributed to segment profit.

service
Equipment & Construction

Handles cutting equipment, welding materials, machinery, compound semiconductor manufacturing equipment, electronics-related equipment, and construction. In the current period, revenue increased in the electronics area due to progress on medium- to large-scale construction projects, while industrial gas-related equipment and construction saw a decline.

product
Medical Gases & Equipment

Provides medical gases such as medical oxygen and nitrous oxide, and medical equipment, to hospitals and home healthcare. Also handles stable isotopes. The medical field is a stable revenue source where regulatory compliance and quality control serve as barriers to entry.

product
LP Gas & Related Equipment

Supplies LP Gas and sells and maintains related equipment. In the current period, LP Gas shipment volumes declined, contributing to lower revenue. This area is subject to business portfolio review.

Growth Drivers

  • Progress on medium- to large-scale electronics-related construction projects and capture of semiconductor-related gas and equipment demand
  • Improved profitability through price management effects on carbon dioxide, packaged gases, and electronic materials gases
  • Recovery and expansion of electronic materials gas demand amid growth in the domestic electronics industry
  • Margin improvement through profitability enhancement programs and business portfolio review
  • Continued stable demand in medical gases and home healthcare

Risks

  • Continued declining trend in Separate Gases and LP Gas shipment volumes
  • Risk of sluggish demand for industrial gas-related equipment and construction
  • Risk of weakening electronic materials gas demand amid deterioration in semiconductor market conditions
  • Risk of renewed increases in energy costs (electricity rates)
  • Risk of fluctuations in equipment and construction demand due to domestic manufacturing capital expenditure trends and economic downturn
  • Structural revenue decline impact from converting certain On-Site subsidiaries for specific customers into joint operations and deconsolidating the household LP Gas subsidiary
