Japan's water-treatment market continues to benefit from stable demand, while renewal of aging water and sewerage infrastructure and the accelerated adoption of closed-water systems are key features. Growing demand for ultrapure water in the semiconductor and pharmaceutical sectors and stronger public-private partnerships are cited as future growth drivers.
Japan's domestic water-treatment market continues to see stable demand, centered on industrial applications and water and sewerage infrastructure. Investment in ultrapure water and advanced wastewater-treatment facilities is active, while responding to stricter water-quality standards and improving recycling rates is essential. Demand to renew aging water and sewerage facilities is gathering pace, public-private partnerships (PPP/PFI) are being adopted more widely, and closed-water systems are being introduced more rapidly across the manufacturing sector.
By application, the main segments are drinking-water and wastewater treatment, industrial water treatment, commercial and institutional facilities, water-supply equipment, power-generation water treatment, and process-water treatment for food and beverages. Demand characteristics vary by segment: urban areas are mature, while industrial, food and beverage applications are growing and residential applications are mature.
Key companies supporting demand include Kurita Water Industries, ORGANO, Toray, Mitsubishi Chemical, Ebara, Hitachi, Matsushita Electric and Cuburra Systems. Going forward, renewal of aging infrastructure and investment in advanced treatment technologies are expected to continue driving growth.
