For nearly 90 years, Takuma has played a vital role in supporting people’s daily lives and industries. Through the design and construction (plant engineering) of essential infrastructure such as waste treatment facilities, sewage treatment plants, and energy plants—as well as through comprehensive after-sales services. Takuma continues to contribute to environmental protection and the stable supply of energy by constructing and maintaining these critical facilities.
The business contributes to solutions that address issues faced by customers and communities through the construction of plants necessary for the utilization of renewable energy and preservation of the environment and provision of after-sales services. This includes municipal solid waste treatment plants, water treatment plants, and energy plants.
Our business is built on two pillars: the “EPC business,” which primarily design and construction of plants, and “after-sales services (recurring revenue model business),” which manages plant operation and maintenance.
In the EPC business, which begins after receiving an order for a project through sales activities, we spend several years in dialogue with the customer, while designing the plant, procuring equipment, and constructing and commissioning the plant. While the construction company working with us on this project begins civil engineering and construction work on site, we will first proceed with the detailed design of the plant, and then procure and manufacture the equipment based on the specifications. Once the civil engineering work has progressed to a certain degree, we will begin the plant construction work. After the plant is constructed and its performance is verified through trial operation, the plant is finally delivered to the customer.
Founded by inventor Tsunekichi Takuma, who developed Japan's first domestically produced boiler "TAKUMA boiler", our company has expanded its business scope into plant engineering for the environmental and energy fields by leveraging core technologies cultivated through boiler refinement and improvement. Our plants incorporate core technologies developed since our founding, including combustion technology, heat recovery technology, and exhaust gas treatment technology.

The after-sales service business after delivery includes plant operation management and maintenance. We also offer “O&M” (Operation & Maintenance) services in which these services are performed on a long-term, comprehensive basis. The plants we deliver play an important role as infrastructure that supports local communities and our customers’ businesses, and it is critical that they operate stably over the long term. While maximizing the facility’s functions through daily operation and management, we strive to ensure safe and stable operation by preventing problems through periodic inspections and maintenance.
We provide solutions that extend throughout the plant life cycle, from construction (EPC) of municipal solid waste treatment plants for local governments to maintenance, primary equipment improvement and service life extension, operation management, and operation (O&M).

Takuma Energy Co., Ltd., a Group company, operates the Power Retail Business, which draws on power generated by municipal solid waste treatment plants and biomass power plants that Takuma has delivered as its principal sources of power. Contribute to stabilizing customers’ electricity rates and reducing greenhouse gas emissions through the procurement and supply of electricity generated from renewable energy and non-fossil fuels.
In response to the increasing demand for biomass power plants, as well as waste treatment due to urbanization in Southeast Asian countries, we provide plant construction and maintenance services primarily in Thailand and Taiwan, where we have local subsidiaries.
