Business Details

Centered on the manufacture and sale of cement, this segment also encompasses the manufacture and sale of ready-mixed concrete and cement-based solidifying materials, power supply, raw fuel recycling, and engineering services. Manufacturing is handled by the Company, Hachinohe Cement, and Wakayama Blast Furnace Cement, with sales conducted domestically and internationally through a network of authorized distributors. Amid the continuing structural contraction of domestic demand, restoring profitability through price revisions and manufacturing cost improvements remains the most critical challenge.

Recent Overview

The effect of price revisions drove a sharp recovery in Cement segment operating income, up 526% year on year to ¥5,495 million.

In FY2026 (ending March 2026), although domestic cement sales volume declined from the prior period (industry-wide domestic demand fell 6.5% year on year to 30,532 thousand tons), the implementation of domestic price increases in response to cost increases proved effective, resulting in net sales of ¥158,799 million (up 1.5% year on year) and a substantial increase in operating income to ¥5,495 million (up ¥4,617 million, or 526.0%, year on year). On the other hand, an impairment loss on fixed assets of ¥3,118 million was recorded in the Cement segment.

Key Products

product
Various Cements & Cement-Based Solidifying Materials

Produced at domestic manufacturing sites (the Company, Hachinohe Cement, and Wakayama Blast Furnace Cement) and supplied to public and private sector demand through a network of authorized distributors. Price revisions in response to cost increases are being implemented on an ongoing basis.

product
Ready-Mixed Concrete

As a downstream business of cement, this segment manufactures and sells ready-mixed concrete to capture construction demand. It is a business area particularly susceptible to labor shortages in the construction industry and the spread of the two-day weekend system.

service
Power Supply & Raw Fuel Recycling

Leveraging the high-temperature processing capability of cement kilns, this recycling business accepts waste and by-products for use as raw fuel. It also contributes to manufacturing cost improvement through substitution for fossil energy.

service
Engineering (Chiyoda Engineering)

Handled by Chiyoda Engineering Co., Ltd., which was transferred from the "Others" segment to this segment from FY2025 (ended March 2025). Provides design, construction, and maintenance of cement manufacturing facilities.

Growth Drivers

  • Recovery of Cement business profitability through implementation of domestic price increases
  • Improvement in manufacturing costs through expanded collection of fossil energy substitutes (waste and by-products)
  • Increase in export sales volume (industry-wide exports up 7.1% year on year in FY2026)
  • Expansion of overseas business, including the Australian terminal business
  • Development of new businesses in the decarbonization field (including product development using artificial limestone)

Risks

  • Structural contraction of domestic cement demand (industry-wide FY2026: down 6.5% year on year to 30,532 thousand tons)
  • Decline in public and private sector demand due to chronic labor shortages in the construction and logistics industries and the spread of the two-day weekend system
  • Risk of rising raw fuel and energy costs
  • Risk of fluctuation in power purchase prices
  • Risk of impairment of fixed assets in the Cement business (an impairment loss of ¥3,118 million was recorded in FY2026)
  • Risk of downward pressure on construction demand due to deterioration in the external environment, including US trade policy and Middle East affairs
