Our second factory discharges approximately 1 tons of water per day, most of which is wastewater from the manufacturing process of 'anko', which contains organic matter such as carbohydrates, proteins, and lipids.
We use a method called the activated sludge method, in which aerobic microorganisms are used to break down organic matter in wastewater by supplying sufficient oxygen, turning the wastewater into clean treated water that is then returned to nature.
The excess sludge resulting from the proliferation of microorganisms is dehydrated and used in agriculture as a nationally approved fertilizer.

The term "cogeneration system" means "producing two things." The system installed at the Second Factory uses gas as fuel to generate electricity and steam within the factory and utilizes them effectively, aiming to make the factory environmentally friendly by reducing CO2 emissions and saving energy.

Solar panels are installed on the roof of the facilities within the Second Factory, and the electricity generated is supplied to and used within the factory facilities.

Once a month, we hold a special sale of non-standard Japanese sweets that are generated on the production line, as part of our efforts to reduce food waste. (Non-standard products: those that are out of shape, have scratches, have excess bean paste spilling out, are of uneven size, etc.)

Through the experience of making Japanese sweets, we are carrying out activities to pass on the "culture of Japanese sweets," one of Japan's traditional cultures.

In addition, starting in 2022, we will be holding on-site confectionery classes at elementary schools in Narita City.

We provide and offer the NAGOMI-YONEYA Sohonten Gallery and Nagomi Gallery Iidacho as places for lifelong learning for local residents.

Every April, we donate yellow carrier bags to new students entering elementary schools in Narita City as a prayer for their safety on the roads.
