COMMON PATTERNS:

  • Time + 以降(いこう) (from [time] onward)
  • 以降(いこう) at the start of a sentence (from then on)

SIMILAR EXPRESSIONS:

  • 以来(いらい) (since - emphasizes continuation from the past)
  • 以後(いご) (after - slightly more formal)
  • (あと) (after - more casual)

NOTE: 以降(いこう) typically includes the reference point, so 10()以降(いこう) means '10 o'clock and after.'
