The Nikkei share average ended 0.3 percent higher at 17,014.78 after trading in negative territory. The index rose for a fourth day, the longest winning streak since November 2015.
For the week, the Nikkei added 5.1 percent, posting the third weekly gains.
The broader Topix rose 0.5 percent to 1,375.35 while the JPX-Nikkei Index 400 advanced 0.2 percent to 12,444.36. (Reporting by Ayai Tomisawa; Editing by Simon Cameron-Moore)
