By Reuters Staff 3 Min Read TOKYO, June 10 (Reuters) - Japanese shares inched higher on Thursday, as the service sector gained on prospects of economic reopenings and drugmakers rose on reports of government support, though Eisai eased after a big jump following U.S. approval of its Alzheimer’s disease drug. Nikkei share average rose 0.42% to 28,982.70 while the broader Topix added 0.18% to 1,960.60. Hopes of economic reopenings amid a steady vaccine rollout underpinned real-estate companies, railway operators and airline companies, though some of them started to lose momentum after a steady rally so far this month. Japan plans to finish vaccinating all citizens who have applied for shots by October-November, Prime Minister Yoshihide Suga said during a debate between party leaders on Wednesday.
