Also written in hiragana as しあさって. Composed of し (an intensifying prefix) + 明後日(あさって) (the day after tomorrow). Part of the Japanese temporal sequence:

  • 今日(きょう) (today)
  • 明日(あした) (tomorrow)
  • 明後日(あさって) (day after tomorrow)
  • 明明後日(しあさって) (three days from now)

  • 一昨日(おととい) — the day before yesterday

REGIONAL NOTE:
In some regions of Japan (particularly parts of Kansai), しあさって means four days from now, while 明明後日(ささって) or やのあさって refers to three days from now. The standard/Tokyo meaning is three days from now. This regional difference can cause confusion, so when precision matters, it is safer to specify the actual date.
