Take Five: Much to say in Tokyo (and Davos)

LONDON (Reuters) -Japan's central bank looks set to raise its inflation forecasts and debate further policy tweaks, just as business leaders and policymakers descend (in person

this time) on the Swiss resort of Davos to put the world to rights. U.S. earnings and retail sales numbers, a slew of China data and inflation readings elsewhere mean

there's plenty to mull over. Here's a look at the week ahead in markets from Kevin Buckland in Tokyo, Tom Westbrook in Singapore, Ira Iosebashvili in New York and Amanda

Cooper and Karin Strohecker in London. 1/ WATCH THE BOJ The Bank of Japan concludes a two-day meeting on Wednesday and investors bet it will blink, just four weeks

after stunning markets by doubling the size of the band it allows 10-year bond yields (JGB) to move around zero. The benchmark yield soared as high as 0.54% on Friday,

punching through the 0.5% ceiling for the first time after butting against it in previous sessions. A media report that officials will examine the bond market distortions from

massive BOJ stimulus appears to have been the final straw. The yen hit a fresh seven-month peak. And the case for ultra-easy policy certainly seems to be weakening. Recent

data showed Tokyo inflation at double the central bank's target. And Japanese workers will hope a decision by Uniqlo's parent company to hike wages as high as 40% will set a

trend. 2/ LET IT SNOW A record number of world leaders, policy makers and top corporate chiefs head to the World Economic Forum (WEF) in the Swiss ski resort of Davos
