I have picked up here some live cases of awarded projects of whole sale and retailer of Business Restructuring Grant Program (事業再構築補助金 Jigyo Saikochiku Kojokin) (the 3rd round of 2021). Among them, many businesses in the whole sale and retail industry chose to switch from face-to-face service to online service, such as switching from retail store sales to online sales and starting online showroom and live streaming of housing building materials and artwork. Also, there are many cases of starting new businesses to meet the demand for anti-virus and decarbonation utilizing existing know-hows, such as a home-use battery developer / seller starting business of industry-use battery for decarbonation.
