Because our craft relies on a harmonious collaboration with nature, we are committed to repaying her blessings and ensuring sustainability.
Fuel for the future
In 2009, Hikari Miso made a significant change in our miso production process by replacing the boiler fuel at our Iijima Green factory, heavy oil, with liquid natural gas (LNG).
LNG emits less carbon dioxide and nitrogen oxide when it is burning than other commonly used fuels, and it does not emit the contaminant sulfur dioxide like fossil fuels do.
Building upon this momentum, in 2013, an oil-based boiler fuel in the processed food factory was switched to liquified petroleum gas (LPG). Like LNG, LPG has lower carbon dioxide emissions than fossil fuels.
Thanks to these bold efforts, Hikari Miso achieved our goal of zero heavy oil use at our Iijima Green factory.
Saving energy, preserving nature
Water plays a vital role in the process of making miso. As such, we generate a large amount of wastewater, which we purify and discharge at wastewater treatment facilities in accordance with legal water quality standards. Grains and plants from the cleaning process are utilized as feed for the farmers in the neighborhood. Dehydrated sludge is also used as fertilizer.
In 2009 we installed a methane fermentation reactor at our Iijima Green factory. These tanks re-ferment the dehydrated sludge and generate methane gas, used as biomass boiler fuel. This led to significant energy savings and a large reduction of industrial waste disposal.
At Hikari Miso, we are mindful stewards of the earth. As we work in harmony with nature to craft the finest miso, we also work to help Nagano’s environment flourish for the benefit of all.
Since 2004, Hikari Miso has supported the C. W. Nicol Afan Woodland Trust in an effort to preserve the Nagano woodlands and expand forestation rich in biodiversity for generations to come.
Our source of life, restored
Lake Suwa in Nagano, Japan, was always known for its pristine water quality. But in the 1970s, the water quality declined drastically due to pollution caused by wastewater from factories, farmlands, and households.
Thanks to basin sewage improvements and water quality improvement efforts by Hikari Miso and the citizens of Nagano, the purity of Lake Suwa’s water has been greatly restored. We accept our responsibility to conduct our craft and business in a manner that supports and enriches the nature of Nagano.
Giving back to our community
In an effort to reduce waste and improve the quality of life for those who are food insecure, Hikari Miso shares products with Second Harvest Japan, a nonprofit food bank. Since we began our partnership with Second Harvest Japan in 2004, we have been providing miso to people in need of food support.
Goodness for Generations
Miso is an ancient food that has been a staple of the Japanese diet for 1,300 years. Its powerful properties, cultivated through fermentation, support the health and vitality of Japanese people and miso-savvy cooks everywhere.
As Japan’s leading miso producer and the number one maker of certified organic miso in the world, we seek to share the magic of miso and Japanese food culture with the next generation, who face a 21st century barrage of food options every day.
