Joyful Honda is working on “creation of stores with a lower environmental impact” and “promotion of environmental activities through products” for the sake of a more prosperous future.

Creation of stores with a lower environmental impact

A Zero-Energy Building (ZEB) is a building which provides a comfortable indoor environment with significantly low energy consumption annually through energy conservation by using high-heat insulation materials, sunlight shading, renewable energy and highly efficient equipment, as well as through energy creation with solar power generation, etc.

For the goals of the ZEB Initiative, please see:

Promotion of Zero-Energy Building (ZEB) Initiative

The Home Center Chiba Store has completed its renovation and reopened on April 23, 2018. The store received a support grant from the fiscal 2017 ZEB Demonstration Project, which is aimed at promoting energy conservation investment by the Ministry of Economy, Trade and Industry. Actual energy consumption recorded in the 1st-year verification was found to be 67.5% less than a standard building and 15% down from the ZEB design value, meaning that the store achieved its targets.

The renovation of Joyful Athletic Club Tsuchiura has been completed and a grand opening was held on July 15, 2019. The building is the Company’s second ZEB building to be constructed with a subsidy from the FY2018 ZEB Demonstration Project. The building is Japan’s first athletic club to obtain ZEBReady status.

Reduction in CO2 emissions

LED lighting

By replacing store and head office lighting with energy-saving LED lighting, adjusting to proper illumination levels, and reducing power consumption, Joyful Honda is striving to prevent global warming through a reduction in CO₂ emissions.


In line with our maintenance program, we are replacing older, inefficient air-conditioning units in stores and head office with new, more efficient models. Electric air-conditioning has been replaced with more energy efficient GHP (gas heat pump) units in ten of our 15 home centers. In addition to reducing crude oil-equivalent energy consumption, we are taking the leveling out of power demand into consideration at our facilities. Further, in the Satte and Nitta areas, we are striving to prevent global warming and reduce CO₂ emissions by switching from LP gas GHP to city gas GHP, which has a lower CO₂ coefficient, in line with new infrastructure development.

Replacing lighting and air-conditioning units has helped reduce CO₂ emissions of the entire Group by more than 37 percent over five years.
(CO₂ emissions: 37,270 tons April 2013 – March 2014: → 25,835 tons April 2020 – March 2021)


Solar power generation

Overview of installed facilities

Solar power modules

Total output: 444.44kW (410W x 1,084 panels)

Power conditioners

Total output: 300kW (100kW x 3 units)

Storage batteries

Standard capacity: 356.2kWh (178.1kWh x 2 units)

Purpose of installation

We installed a solar power generation system and storage batteries for in-house consumption on the roof of the Mizuho store, which is a large store. The purpose of the project is to reduce greenhouse gas emissions, reduce the load on the power grid, and provide a power source to operate facilities at the store for several hours in the event of a disaster.

Information that serves as a reference for the introduction of renewable energy facilities to other companies

In addition to the benefits of using renewable energy during business as usual, the project is expected to supply power to temporary waiting areas for employees, some sales activities, and the pet store area in the event of a disaster. The capacity (356.2kWh) is designed such that even if the storage battery capacity reaches the lower limit (20% around 20:00) during a power outage, it will not run out until the next morning, when solar power generation begins.

Details of energy conservation initiatives

We are promoting the conversion to ZEB (Zero-Energy Buildings), the introduction of LED lighting and high-efficiency air conditioning, and the installation of solar power generation equipment at each of our stores.

Electric car battery-charging facilities

We have installed ordinary battery chargers and rapid battery chargers for electric cars at all stores (except the Chiba store) in line with the spread of eco-friendly electric cars.

  • 5 large stores: 20 ordinary chargers and 1 rapid charger in each store
  • 9 medium stores: 2-3 ordinary chargers and 1 rapid charger in each store
  • Total number of vehicles using chargers per year across all stores: Approximately 26,000 (April 2019 – March 2020)

Promotion of environmental activities through products

Environmentally friendly packaging containers

We are promoting adoption of environmentally friendly product packaging for merchandise packaging and containers with the aim of achieving labor savings in waste disposal.

Unwanted soil collection service

Our garden centers provide a collection service for unneeded soil and uses the recycled potting soil made from the recovered soil to make potted flower baskets.

  • The soil collection service is available only to customers who have purchased potting soil designated by the Company and bring the unwanted soil placed in its empty bag to our stores. The collected soil is intended for recycling and therefore must be free of things like trash, branches and pebbles.

Reducing waste by recovering resources at stores

Recycling Station

The Home Center Utsunomiya Store and Satte Store have set up a recycling station for PET bottles, empty cans, and paper, in an effort to reduce waste and recycle reusable resources.
Customers who cooperate with the recovery of these resources will receive points that can be exchanged for Joyful Honda gift cards. The recovered waste is delivered to a private-sector recycling operator, where it is transformed into new resources at recycling plants.
