Site Report

The Atsugi Site is located in Atsugi City, Kanagawa Prefecture. It is the Group's largest base, with approximately 2,000 employees, who account for half of all employees, and emitting approximately 50% of all greenhouse gases (Scope 1+2). Anritsu Corporation is the hub of the Anritsu Group's ESG activities, and most of the research and development is also carried out here. Group companies such as Anritsu Infivis, Anritsu Devices, and Anritsu Customer Support are also located on the same premises, and they are engaged in manufacturing, repair and calibration services, and business support. There is also a central location for domestic sales in Atsugi City, and the total environmental impact data for each location is calculated together as the Atsugi Site.

Initiatives to Reduce CO₂ Emissions

The Global Headquarters Building on the Atsugi Site is a building with the highest environmental performance and BCP functions in the "CASBEE Kanagawa (Comprehensive Assessment System for Built Environment Efficiency)" of Kanagawa Prefecture. The site features solar carports and solar panels with a maximum output of 688 kW, capable of supplying approximately 6% of the Atsugi Site's electricity consumption. In FY2024, we purchased J-Credits worth 130 tons of CO₂ to offset our CO₂ emissions. Our domestic sales offices in Atsugi City purchase 100% CO₂-free electricity.

Tohoku Anritsu as the great mother factory of the Anritsu Group, produces and ships products that support cutting-edge information and communications systems, such as measuring instruments for mobile communication terminals, measuring instruments for optical and ultra-highspeed digital communication networks, and bandwidth control devices, both domestically and internationally. We have a flexible production system that enables us to deliver quickly and at low cost, and we carry out thorough quality control and environmentally friendly production activities.

Today, information and communication systems have become an indispensable infrastructure for social development, and we are promoting manufacturing that is useful for people and society by staying ahead of the latest technology.

Initiatives to Reduce CO₂ Emissions

In July 2023, we constructed and began operating a power generation system at the Tohoku Anritsu second factory, combining a 1,300 kW solar power generation facility with a large-capacity storage battery (NAS battery; Rated output: 400 kW, Rated capacity: 2,400 kWh). Using stored electricity at night increases private consumption rates, while utilizing battery power during the evening and beyond - when grid power becomes strained - also contributes to mitigating power shortage risks. In FY2024, the plant generated 1305 MWh of electricity and covered 28.8% of its electricity consumption with private solar power generation. The storage battery charged 356 MWh of surplus electricity generated during the day and supplied 284 MWh of electricity.

Zero plastic waste project

Tohoku Anritsu is promoting efforts to eliminate plastic waste by 2030. We implemented measures such as replacing cushioning materials used for product shipping with biomass PEF, reducing inline packaging, and cutting down on CD and DVD-ROM media. This resulted in a 2.2-fold reduction in plastic compared to the previous year, achieving a reduction rate of 45%.

Takasago provides power supply solutions that meet zero-emission requirements through technologies that freely control energy, such as emulation, power regeneration, bidirectional control, and full digital control. At the Tsuruoka Plant, our production location, we are working to improve productivity through measures such as “level production,”“visualization of production status,” and “flexible production lines,” in order to stably supply highquality products that meet customer needs. We are also working to reduce the energy used in production by eliminating waste from the process.

Initiatives to Reduce CO₂ Emissions

We have introduced our main product, the “electricity regeneration power supply,” into our inspection equipment, and are reusing approximately 80% of the electricity that was previously consumed as heat. This also helps to reduce the load on the air conditioning system by reducing the amount of waste heat from the equipment.

Resource Recycling Initiatives

With the cooperation of our suppliers, we are promoting the reuse of packaging and cushioning materials used in deliveries and the sorting and disposal of waste for recycling.

Anritsu Techmac manufactures precision-cut and sheet metal parts for use in Anritsu Group products. We also provide design support and production of prototype models during the development stage, and we make proposals for drawings that take cost considerations into account from a manufacturing perspective. In terms of the environment, some of the site boundaries are adjacent to residential areas, so we have taken care to avoid the noise that is characteristic of metalworking, and have installed noisy equipment in separate rooms. We have taken measures to reduce the noise from exhaust vents, and we measure the noise at the property boundary every year to make sure there are no problems. We recycle the rinse water used to rinse degreasing and cleaning equipment for metal materials, and we have switched the drinks sold from vending machines from plastic bottles to cans, achieving zero plastic bottle waste on the site.

Community Contribution Initiatives

At Anritsu Techmac, all employees participate in cleanup activities around the factory every Monday with the aim of contributing to the local community and raising employee awareness of volunteerism.

Anritsu Company is engaged in the research and development, manufacturing, sales, support, repair, and calibration of solutions used in the performance evaluation of wired and wireless communication devices. All equipment and devices are manufactured and assembled locally. The premises include a 669 m2 clean room, a 780 m2 machining center, and a calibration laboratory that has received national certification.

Environmental Initiatives

The building's rooftop and carport are equipped with 2,774 solar panels, which generate 1,100 kW of electricity through a private renewable energy power generation system. Electric vehicle charging facilities are also installed in the parking area. We are also actively involved in recycling, and by sorting out items that can be composted and compressing waste, we have reduced landfill waste by 60%. We also recycle all waste materials from old electronic devices and from manufacturing and processing processes. On the grounds other than the asphalt parking lot, we have planted grass and plants that are resistant to dryness to create a lush green landscape.
