Alternative spelling
明々後日

Compound of し (shi, of uncertain derivation) +‎ 明後日 (asatte, “the day after tomorrow”).^[1]^[2]^[3]

The initial shi element is uncertain. Speculatively, this might be related to, or a shift from, intensifying prefix ひ (hi) found in some adjectives, such as ひ弱(よわ)い (hiyowai, “delicate, very weak”).

First cited to a text from 1275.^[1]

Pronunciation

(Tokyo) しあさって [shìásáꜜttè] (Nakadaka – [3])^[3]
IPA^(key): [ɕia̠sa̠t̚te̞]

Noun

明明後日(しあさって) • (shiasatte)

[from 1275] (Tōkyō, Kansai, western Japan) three days from today, two days after tomorrow
Synonym: (eastern Japan) 弥の明後日 (yanoasatte)
(Kantō, Hokkaidō, Mie, Hida Province) four days from today

Usage notes

This term and 弥の明後日 (yanoasatte) share a roughly complementary distribution between eastern and western Japan, wherein the terms alternate between meaning "three days from today" and "four days from today". Tokyo follows the Western Japan usage.
