TOKYO -- Undeterred by a huge loss on U.S. office-sharing platform WeWork, SoftBank Group CEO Masayoshi Son has set his sights on a new big plan: building a sweeping online ecosystem akin to China's Alibaba Group Holding.
Z Holdings, the SoftBank-owned parent of Yahoo Japan, and South Korea's Naver, which owns the popular chat app Line, are in final negotiations to bring the two internet companies under a single umbrella, Nikkei has learned.
