When did it enter Japanese?

Chinese characters reached Japan through a long process of contact. Early inscribed objects and sixth-century Japanese names are documented; this is context for the writing system, not a first date for 穴.

穴 appears in the current Jōyō kanji table published on 30 November 2010. This records modern standard status, not the date the character was first used in Japan.

A dated first Japanese use for 穴 has not been verified in the sources attached to this entry.
