We've got Janet Yellen speaking at the top of the hour, and Japanese CPI data a little later.

Apart from that I see nothing of FX market significance on the calendar for the Asian timezone.

Due at 2330GMT (note that time ladies and gentlemen, 2330GMT, that's 20 minutes earlier than the usual Japan data time)

2330GMT National CPI y/y for August,

  • expected is +0.1%, prior was +0.2%

2330GMT National CPI y/y excluding Fresh Food for August,

  • expected is -0.1%, prior was 0.0%

2330GMT National CPI excluding Food, Energy y/y for August,

  • expected is 0.7%, prior was 0.6%

2330GMT Tokyo CPI y/y for September,

  • expected is -0.1%, prior was 0.1% (Tokyo CPI data is available a month earlier than the National CPI)

2330GMT Tokyo CPI excluding Fresh Food y/y for September,

  • expected is -0.2%, prior was -0.1%

2330GMT Tokyo CPI excluding Food, Energy y/y for September,

  • expected is 0.5%, prior was 0.4%

Check out the CPI excluding Food, Energy ... referred to as 'core-core' CPI in Japan ... that is giving some positive indications of edging in the right direction towards the authorities' 2% goal. Note 'some positive indications of edging in the right direction towards' ... that's about the best that can be said about the inflation goal.

A disappointment on the data today should be a negative input for the yen (and vice versa), though FX market response to Japanese data is often very muted.

Not an immediate forex market focus data point this one.
