Effective July 2012, the government of Japan implemented a feed-in tariff (FIT) system for purchasing power generated under the renewable energy promotion project.
Joshin planned to install a photovoltaic system in Aridagawa Store, a planned new store, intending for all-quantity buyback.
Power utilities purchase electricity generated at 40 yen (plus tax) for a period of 20 years.
For a store that generates power off the grid, at an average electricity purchase price of 14 yen, it would take 26 years to recover the installation cost, but at the purchase price of 40 yen (plus tax), it would take only about nine years.
Based on this simulation, we proposed a business plan under which we would be able to recover the initial costs in 10 years and then make profits in another 10 years.

* Himeji Higashi Store and Sotokan Kashiwara Store installed a photovoltaic system not only for selling electricity but also for counting it as a green space area in building the store.
3,066,718.41Kg-CO2/year
※Total CO2 emission reduction of 27 business sites
• Calculated with METI’s CO_{2} emission coefficient of 0.441kg-CO_{2}/kWh.
We have photovoltaic systems for the FIT program in place at 27 business sites at present. The total electricity sales per year amount to approximately 200 million yen.
