Across Japan, a decline in public transport and small retailers is said to have left as many as 7 million seniors unable to access basic daily necessities. 6 years ago, to address the needs of these "shopping deprived," former magazine editor Tatsuya Sumitomo set up a mobile supermarket service. Now with over 300 trucks, each offering up to 1,200 items, along with clothing and monitor services, his business regularly serves around 40,000 people nationwide, with an average age of 80.
