Business Details

The company manufactures, supplies, and sells City Gas mainly in Sapporo City, Otaru City, Hakodate City, Chitose City, Kitami City and other supply areas. LNG shipment and transportation is outsourced to Hokkaido LNG Co., Ltd., meter reading operations to Hokugas Service Co., Ltd., and safety/inspection operations to Hokugas Fleast Co., Ltd. and other consolidated subsidiaries and equity-method affiliates. The main products and services are City Gas and LNG Sales. This is the core segment of the Group, accounting for approximately 62% of consolidated net sales, and is responsible for the energy business centered on natural gas.

Recent Overview

Achieved significant profit growth with sales volume up 5.8% and segment profit up 19.8%.

In FY2026 (ending March 2026), Gas segment net sales were ¥108,064 million (up 3.1% year on year), and segment profit was ¥15,129 million (up 19.8% year on year). Although the selling unit price under the raw material cost adjustment system declined, this was offset by increased residential heating demand (up 6.8%) due to low temperatures and record snowfall in early spring and early winter, and increased commercial air conditioning demand (up 5.1%) due to high summer temperatures. The consolidation of Muroran Gas Co., Ltd. (during the fiscal year) expanded the supply area and customer base. On the other hand, the number of retail customers continued a slight decline, down 510 to 487,990.

Key Products

Promoting standardization of the energy management system centered on natural gas. Also utilized to expand local production and consumption of energy in collaboration with municipalities within Hokkaido.

product
Gas Smart Meter

Currently promoting the "heating/cooking single-meter integration construction," which consolidates the two meters for heating and cooking into a single meter. As of the end of FY2026 (ending March 2026), the number of units with integrated heating/cooking meters was 573,240 (up 7,435 units year on year). The company aims to improve customer convenience and operational efficiency through the introduction of smart meters.

Growth Drivers

  • Increase in residential Gas sales volume (expanded heating demand due to low temperatures and record snowfall, increase in installed meters mainly at rental properties)
  • Expansion of commercial demand (increased air conditioning demand due to high summer temperatures, improved operating rates in commercial and industrial sectors)
  • Expansion of wholesale supply to other operators (FY2026 (ending March 2026): up 6.9% year on year to 34,293 thousand m³)
  • Expansion of supply area and customer base through consolidation of Muroran Gas Co., Ltd. as a subsidiary
  • Capture of new demand such as LNG bunkering supply for marine fuel
  • Improved operational efficiency and customer convenience through promotion of heating/cooking single-meter integration construction

Risks

  • Decline in selling unit price under the raw material cost adjustment system (foreign exchange and crude oil price fluctuation risk)
  • Profit pressure due to increased strategic expenses such as DX investment and smart meter introduction
  • Declining trend in number of retail customers due to decrease in completed new detached houses and condominiums (FY2026 (ending March 2026): down 510 year on year to 487,990)
  • Uncertainty in LNG procurement costs due to prolonged geopolitical risk and U.S. policy developments
  • Risk of long-term structural change in natural gas demand due to the trend toward decarbonization
  • Recording of a provision for repairs related to periodic inspection and dredging work at the Ishikari Power Plant (a decrease in profit of ¥113 million due to a change in accounting estimates)
  • Seasonal fluctuation factor with sales concentrated from winter to early spring

Business Details

Hokkaido Gas Co., Ltd. generates and sells electricity with Hokkaido as its sales area. The consolidated subsidiary Hokugas Genex Co., Ltd. is responsible for the solar power generation business and sells electricity to the company, while the equity-method affiliate Tomakomai Biomass Power Generation Co., Ltd. conducts a woody biomass power generation business and supplies electricity to the company. The company has a wide range of customers, from low-voltage residential to high-voltage and wholesale, and is promoting the acquisition of residential customers through campaigns and mass PR aimed at expanding combined Gas and electricity contracts.

Recent Overview

Sales volume expanded, but profit fell 19.3% due to lower unit prices under the fuel cost adjustment system and increased repair costs

In the Electricity segment for FY2026 (ending March 2026), the number of customers increased by 662 to 257,271, and total sales volume also expanded 1.9% to 861,929 thousand kWh, due to measures to expand combined Gas and electricity contracts. On the other hand, net sales were only 28,528 million yen (down 2.1% year on year) due to a decline in the selling unit price under the fuel cost adjustment system, and segment profit fell sharply by 19.3% year on year to 2,911 million yen, compounded by increased repair costs. For the next fiscal year (FY2027, ending March 2027), a worsening of the electricity business's earnings due to a surge in wholesale electricity market prices caused by instability in the Middle East situation has been factored into earnings forecasts, and is expected to continue to be a factor pressuring profitability.

Business Details

The "Other" segment encompasses businesses not included in the three main reportable segments (Gas, Electricity, and Energy-Related), such as IT Solutions, real estate, and the insurance agency business. In FY2026 (ending March 2026), the consolidation of Hokugas Lifefront Co., Ltd. as a subsidiary and expansion of system sales resulted in significant increases in both external customer net sales and segment profit. Although the segment's share of overall Group net sales remains small at approximately 1%, profitability improved markedly.

Recent Overview

Net sales and profit both increased significantly due to consolidation of Hokugas Lifefront and expansion of system sales

In FY2026 (ending March 2026), due to the new consolidation of Hokugas Lifefront Co., Ltd. from the beginning of the fiscal year and the expansion of system sales, external customer net sales improved markedly, up 28.3% year on year to ¥1,787 million, and segment profit rose 215.3% year on year to ¥464 million. Segment assets also increased significantly to ¥5,925 million due to the consolidation. The segment profit margin reached a high level of approximately 26%.

Key Products

service
IT Solutions & System Sales

A system sales and IT solutions business that supports the Group's DX promotion. In the current fiscal year, expansion of system sales was one of the main factors behind the increase in segment net sales.

service
Real Estate Business

A business centered on leasing and management of Group-owned real estate through Hokugas G-Plex Co., Ltd. and others. It functions as a complementary revenue source within the segment.

service
Insurance Agency Business

Agency sales of insurance products leveraging the Gas and electricity customer base. This is positioned as part of the Group's cross-selling strategy.

service
Hokugas Lifefront Co., Ltd. (Newly Consolidated)

Although it was a non-consolidated subsidiary as of the end of the prior fiscal year, it was added to the scope of consolidation from the beginning of the current fiscal year due to increased materiality. This contributed significantly to the increase in segment net sales and profit.

Growth Drivers

  • Expansion of business scale and earnings contribution through consolidation of Hokugas Lifefront Co., Ltd. as a subsidiary
  • Capture of demand related to IT solutions accompanying the Group's overall DX promotion (utilization of information platforms)
  • Boost to segment net sales and profit through continued expansion of system sales

Risks

  • Structural downward pressure on net sales and profit due to the shrinking of outsourced operations, such as the termination of the water meter reading business
  • High dependence on outsourced operations within the Group, creating a risk that changes in outsourcing policy by the main segments would directly affect performance
  • Risk of slowing growth if the temporary scale-expansion effect from the consolidation of Hokugas Lifefront fades
  • The segment's scale remains small relative to the overall Group (external net sales ratio of approximately 1%), so its impact on Group performance is limited
