See these two posts for previews of the BOJ’s meeting today:

BOJ meeting today – setting a target date for 2% inflation

I expect that there will be an attempt higher in USD/JPY after the BOJ announcement today. The option-related interest interest at 100 has diminished (NOT disappeared entirely, though), as options expire. Not all have rolled off, though – there is still interest there.

The market has 100 in its sights. No guarantees, but I expect an attempt at the level.
