Nomura says that a Bank of Japan exit from its negative interest rate policy (NIRP) and yield curve control (YCC) tomorrow is “basically a done deal”.

Adding that the only uncertainty is whether the central bank keeps its
commitment to expanding the monetary base:

• “A lot of people expect that to be dropped, myself
  included”
• “If they keep it, it will be a dovish
  surprise.”

Also, on JGB yields falling, comments from Mizuho Securities:

• “It’s kind of buy the fact,” said Shoki Omori, chief Japan
  desk strategist at Mizuho Securities. “All the information is
  basically out, so people are no longer scared about what the BOJ
  will do tomorrow.”
  While the 10-year yield may jump above 0.8% initially
  following the BOJ policy decision, demand for bonds from life
  insurers and other long-term investors into Japan’s fiscal
  year-end this month could push it as low as 0.7% ultimately,
  Omori said.
