On Wednesday, Japanese wireless operator KDDI joined forces with Sumitomo on a US$2.7 billion bid for the remaining shares of Jupiter Telecommunications that would give the partners joint control of more than half of Japan’s cable television market. Currently, KDDI and Sumitomo hold stakes of 30.7% and 39.9%, respectively, in Jupiter (more commonly known as JCom) which already ranks as the largest cable operator in Japan. KDDI, which acquired its JCom stake two years ago from U.S. media conglomerate Liberty Global, will invest ¥70.9 billion to raise its JCom stake to 50 percent. Sumitomo, which founded JCom in 1995 with Liberty, intends to establish a separate unit with KDDI that will pay ¥145 billion for the remaining JCom shares to raise Sumitomo’s stake to 50 percent. Upon completion of the tender offer, Japan Cablenet—the nation’s second-largest cable operator that is owned 95.6% by KDDI—will be merged into JCom to give the combined entity a 53% share of Japan’s cable market. Executives of KDDI and Sumitomo said they would take advantage of JCom’s position in the Japanese market to expand JCom video offerings to smart phones and other mobile devices.
