TOKYO, Sept 20 (Reuters) - Japanese stocks ended higher on Friday and posted their third straight week of gains as consumer-related shares rose on speculation the Bank of Japan will follow other central banks and ease policy next month.
The Nikkei 225 index rose 0.16% to 22,079.09. Nikkei shares rose 0.4% this week.
There were 122 advancers on the Nikkei index against 97 decliners.
The BOJ kept policy steady on Thursday but signalled its readiness to expand stimulus as early as next month by issuing a stronger warning of overseas risks threatening the export-reliant economy.
"Japanese stocks have risen a lot recently, so I expect an adjustment lower next week, but that would be a chance to buy the dip," said Kiyoshi Ishigane, chief fund manager at Mitsubishi UFJ Kokusai Asset Management Co in Tokyo.
"Shares will be supported by expectations for more monetary easing, expectations for fiscal spending in other countries and optimism about the trade war. The BOJ wants to ease, but it's just having trouble reaching consensus on what to do."
