TOKYO -- Major Japanese companies increasingly are forming departments to analyze "big data" as part of efforts to cut costs, raise product quality or otherwise improve operations.
The Nikkei Inc. group annual survey on big-data use targeted company chiefs including presidents and chairmen, collecting responses from 86 businesses. It found that 67% of the companies use big-data analysis to improve operations, up 14 percentage points from 53% in 2014.
