Yes. Japan Standard Time and Eastern Time don't change their clocks on the same dates, so over the next 12 months:
- October 14 to October 31: 1 AM JST = 12 PM EST the previous day
- November 1 to March 13: 1 AM JST = 11 AM EST the previous day
- March 14 to October 13: 1 AM JST = 12 PM EST the previous day
Eastern Time switches between EST and EDT for daylight saving time; people often say EST all year.
