FY2023
Business Plan
●  Anticipate an increase in sales due to progress and shipments of orders received in the previous period and earlier. (The orders backlog at the beginning of the period is expected to increase by 4.0 billion yen from the previous period.) ●  Plan to increase orders by steadily capturing demand in the energy-saving and energy-creating sectors and the fisheries sector, and from local governments for equipment renewal. ●  Profit margin is expected to remain unchanged from the previous year, as price increases in raw materials and other costs will be absorbed by price pass-throughs and cost-reduction efforts. ●  Plan to increase SG&A expenses due to higher employee benefits on considering inflation and increased R&D-related costs targeting business growth.

Engineering (water- treatment-related) The design, construction, and maintenance of water infrastructure facilities Waterworks Proportion of consolidated net sales Gross profit Proportion of consolidated gross profit Sewerage Rainwater draining facilities Manhole pump facilities Cloud monitoring system E-Qias Cloud We handle design, construction and maintenance work for all equipment and devices to take in water from rivers, lakes and groundwater, from various water treatment equipment through to equipment to supply water to homes and business sites. We handle design, construction, and maintenance work for all types of facilities, equipment and devices including for interim pumping stations that collect contaminated water and send it to sewerage stations, various sewerage stations, and water treatment stations that send clean, treated water back to rivers etc. These facilities are rolled out nationwide to protect the lives of people in areas prone to serious damages from river flooding due to torrential rain from typhoons. We handle the design, construction, and maintenance of rainwater draining pumps and electricity systems for target facilities. These facilities are being used nationwide as a new armor for small-scale contaminated-water-transferring pumping stations, which are essential to spread the use of sewerage systems. The facilities are compact, with a tank to collect contaminated water (manhole) set with an underwater pump and employed in places with insufficient space for other facilities. We offer a system to remotely monitor waterworks and sewerage stations.
