Polite or slightly formal adverb indicating the very recent past. Often used in spoken or written Japanese to refer to something that happened only moments before.
Just a moment ago, I got a call from Mr. Tanaka.
I just arrived a moment ago.
Standard kanji-kana mixed spelling.
Alternate kanji spelling using 方; less common but still encountered.
From 今 “now” followed by the emphatic particle し and 方, which here indicates a point in time: literally, “just at this time.”
