Introduced LED lighting at our main plant

Since the installation of LED lighting in the new main factory constructed in April 2017, our old factory and head office have also been converted to LED lighting. In September 2022, LED lighting had installed in our head office, which resulted in a 55% reduction in power consumption for lighting, and the total power consumption of the head office in FY2023 was reduced by approximately 48,000 kWh compared to the previous fiscal year.
We will continuously make efforts to improve the energy efficiency of our entire plant.

Efficient use of natural energy

We have installed approximately 300 kW of solar panels on the building roofs at our new main factory constructed in April 2017. (Selling electricity)
We have also installed 40 kW of solar panels on our Research & Development Center, which was relocated to our main plant in December 2021, and approximately 531 kW of solar panels on our service factory building located at our main plant in January 2023. (Self-consumption)(871 kW in total)
Through this initiative, we strive to make efficient use of natural energy and reduce our environmental impact.

Improved efficiency of air conditioning and energy

For constructing the exterior walls of our new main factory, we have used building materials with high thermal insulating properties. In addition, we use air-conveying fans to improve air conditioning efficiency and reduce energy consumption to cut down CO2 emissions.
We also work to improve the energy efficiency of our factories by introducing ultra-high efficiency transformers.

Introduction of a plant-wide energy management system

We can manage overall energy usage and implement effective power-saving measures by installing energy demand monitors that visualize energy usage in each area in our main plant.

Introduction of hybrid vehicles in company fleet

We started converting company vehicles to hybrid since FY2021.
Of our 34 company vehicles, we have gradually been switching them to hybrid vehicles from those scheduled for renewal. As of March 31, 2024, approximately 35% of our company vehicles had been converted to hybrid vehicles.
