Bank of Japan Deputy Governor Amamiya is speaking at 3pm Tokyo time today, which is 0600 GMT.

Last week BOJ Governor Kuroda spoke on the March review of policy, and brought up the topic of widening the band for JGBs:

Before adding he does not think its necessary to expand the target band on long term JGBs

The current 'band' is around 0 to 0.2%.
