Does the answer change during the year?

Yes. Japan Standard Time and Eastern Time don't change their clocks on the same dates, so over the next 12 months:

  • November 8 to March 13: 12 PM JST = 10 PM EST the previous day
  • March 14 to November 6: 12 PM JST = 11 PM EST the previous day
  • November 7 to November 7: 12 PM JST = 10 PM EST the previous day

Eastern Time switches between EST and EDT for daylight saving time; people often say EST all year.
