Hikari Miso Expands Use of Renewable Energy
HQ to be Powered Exclusively by CO2-Free “Shinshu Green Electricity”

Posted on May 28, 2023

From June 2023 Hikari Miso Co., Ltd. (Shimosuwa Suwa-gun, Nagano Prefecture) will power its headquarters entirely using “Shinshu Green Electricity” generated without CO2 emissions using the abundant waters of the Shinshu (Nagano) region, a hydroelectric power station operated by the prefectural development office. This will reduce CO2 emissions at Hikari Miso HQ by 92 tons annually.

Hikari Miso first began purchasing Shinshu Green Electricity in April 2022, as part of its environmental protection measures at its Iijima Green factory. The factory uses renewable energy in a number of original ways, including recycling wastewater and sludge generated during the production of miso to produce methane and in turn, clean energy. As a result, the factory operation achieved a reduction in CO2 of 321 tons for the year to March 2023.

Now, by adopting Shinshu Green Electricity to power its HQ, Hikari Miso will extend its use of renewable energy and promote localized energy production and consumption, doubling the company’s commitment to meet the UN SDGs – Sustainable Development Goals – initiatives to reduce CO2 emissions.
