Japan Water and Wastewater Treatment Market Overview, 2028

Wastewater treatment in Japan is characterized by cutting-edge technology and a strong commitment to environmental sustainability. The country faces the challenge of efficiently managing wastewater due to its dense population and limited land resources. To address this, Japan has developed advanced sewage treatment systems that prioritize the removal of contaminants and the protection of its natural ecosystems. Japan places a strong emphasis on wastewater treatment and environmental protection through various government associations and comprehensive regulations. The Ministry of the Environment (MOE) plays a central role in overseeing and regulating wastewater management. One of the key regulations is the Water Pollution Control Act, which establishes strict standards for the discharge of pollutants into water bodies. The Act also requires industries and municipalities to obtain permits for wastewater discharges, promoting responsible wastewater treatment practices. Additionally, Japan has established the Japan Sewage Works Association (JSWA), a national organization that focuses on improving wastewater treatment infrastructure and promoting research and development in the field. Cities like Tokyo, Osaka, and Yokohama, which are major metropolises, have some of the largest and most advanced wastewater treatment facilities in the nation. These regions generate substantial amounts of sewage and industrial wastewater, necessitating extensive treatment infrastructure. Additionally, regions with significant industrial activity, such as the Keihanshin Metropolitan Area (including Osaka, Kyoto, and Kobe), also have a high concentration of wastewater treatment units due to the industrial discharges they handle. Japan's commitment to strict environmental regulations and its focus on water quality preservation have led to the widespread presence of treatment facilities in various municipalities across the country.

According to the research report, “Japan Water and Wastewater Treatment Market Overview, 2028” published by Bonafide Research, the market is anticipated to reach more than USD 7.82 Billion by 2028. The wastewater treatment market in Japan is experiencing significant expansion in recent years. Japan's strong commitment to environmental protection and sustainability drives increased investments in wastewater treatment infrastructure. The government has been actively promoting advanced technologies and sustainable practices to address pollution concerns and protect water resources. The aging infrastructure in many parts of the country has led to the need for upgrades and replacements, providing opportunities for companies involved in wastewater treatment equipment and services. Japan is investing in modernizing its wastewater treatment facilities to meet stringent environmental regulations and enhance the efficiency of water treatment processes. The promotion of water recycling and reuse initiatives, especially in agriculture and industry, is driving demand for advanced wastewater treatment solutions. These efforts not only contribute to sustainable water management but also stimulate the wastewater treatment market. Japan's proactive approach to research and development fosters innovation in wastewater treatment technologies, attracting both domestic and international companies to invest in this growing market.


The Market is segmented into Water & Wastewater Treatment Equipment and Water & Wastewater Treatment Chemicals. The water and wastewater treatment chemicals sector holds the largest market share compared to water and wastewater treatment equipment. Wastewater treatment in industries is a fundamental practice that plays a pivotal role in environmental stewardship, regulatory compliance, and the sustainability of industrial processes worldwide. Industrial wastewater is generated from a myriad of manufacturing, processing, and production activities, and it often contains a wide range of contaminants, including chemicals, heavy metals, organic compounds, and suspended solids. To mitigate the adverse environmental impacts and meet stringent regulations, industries employ specialized wastewater treatment systems tailored to their specific needs. Along with this the wastewater treatment plays a crucial role in municipal infrastructure worldwide, addressing the needs to manage and purify the vast volumes of wastewater generated in urban areas. In municipalities, wastewater treatment facilities are the backbone of environmental protection and public health. These facilities receive wastewater from homes, businesses, and industries, treating it to remove contaminants and pollutants before releasing it back into the environment. The primary objective of municipal wastewater treatment is to safeguard human health and protect the environment, ensuring that water bodies such as rivers, lakes, and oceans are not polluted with harmful substances.

The market is further segmented on the Water & Wastewater Treatment Chemicals, which includes Coagulants & Flocculants, Disinfectants & Biocidal Products, Scale & Corrosion Inhibitors, Antifoam Chemicals, pH adjusters and stabilizers, and Others (Oxidizing Agents, Chelating Agents, Odor Control Chemicals, Precipitants, Color Removal Agents, Sequestrants, Biodegradable Surfactants, etc.) Coagulants and Flocculants dominate the market in 2022 with more than 27% market share. These chemicals play a crucial role in the primary stages of wastewater treatment, where they aid in the removal of suspended particles and colloidal matter by aggregating them into larger, settleable flocs. Following coagulation and flocculants, disinfectants and biocides represent another substantial segment within the wastewater treatment chemicals market. Disinfectants are essential for eliminating harmful microorganisms, bacteria, viruses, and pathogens present in wastewater effluents. Common disinfection agents include chlorine, chlorine dioxide, ozone, and ultraviolet (UV) radiation. Ensuring the removal of these pathogens is vital to prevent the spread of waterborne diseases and ensure the safety of the treated water when it is discharged into the environment or reused for various purposes. Along with this, Scale and corrosion inhibitors represent a crucial and substantial segment within the wastewater treatment chemicals market. These chemicals are specifically designed to combat the detrimental effects of scale formation and corrosion in water and wastewater treatment systems.

The market is further segmented on the Water & Wastewater Treatment Equipment’s; which includes Membrane Separation, Biological, Sludge Treatment, Disinfection, and Others (Sedimentation and Clarification, Ion exchange, etc. As environmental regulations become more stringent, and as the demand for high-quality treated water continues to rise, membrane separation technologies are poised to maintain their significant market share in the wastewater treatment equipment segment. Ongoing advancements in membrane materials, system designs, and operational efficiency further enhance their appeal, solidifying their position as a cornerstone of modern wastewater treatment practices. As stringent regulations, the need for water reuse, and the demand for advanced wastewater treatment continue to grow, UV disinfection equipment is expected to maintain and expand its significant market share. Ongoing advancements in UV technology, including the development of energy-efficient UV lamps and innovative reactor designs, further enhance the appeal of UV disinfection as an essential component of modern wastewater treatment processes.
