TOKYO, Jan 20 (Reuters) - Japan"s Nikkei share average rebounded from a five-month low on Thursday, buoyed by video-game makers Sony and Nintendo, after China ramped up its monetary easing measures to shore up a slowing economy by lowering a set of key policy rates. The Nikkei (.N225) was up 0.46% at 27,594.29 by the midday break. The benchmark survived a sharp mid-morning dip, which pushed the index to its lowest intraday level since Aug. 23, after China"s surprise interest rate cut initially stoked fears of an economic slowdown. With the property downturn seen persisting into 2022 and fast-spreading Omicron variant dampening consumer activity, many analysts in China expect more easing measures will be necessary, despite other major economies appearing set to tighten their monetary policies. read more "The Nikkei has dropped to a level where it looks cheap, tempting investors to come in and buy the dip," said a market participant at a domestic securities firm.
