The Japanese government’s recent adoption of hiragana to write the word for “child” in official documents reflects a broader linguistic and cultural shift surrounding the term's usage. Traditionally, the word 子供 (kodomo) has been the standard spelling, employing kanji characters. However, the government now prefers writing it entirely in hiragana as こども in contexts related to children’s policies.

This change is partly motivated by concerns over the kanji 供, which appears in 子供. Although historically the character 供 served as a plural or collective suffix, as seen in expressions like 私共 (watashidomo, meaning “we” or “us”), some people associate 供 with notions of accompaniment or service, such as in お供 (o-tomo, “attendant” or “companion”) and 供え物 (sonaemono, “offering”). Critics have argued that using 供 in the word for children can carry undesirable implications, suggesting children are subordinate to or possessions of adults.

To address these concerns, a mixed spelling—子ども—with the first kanji for child (子) and the hiragana ども for the plural suffix became common, especially in educational and welfare settings. Nonetheless, the historical origin of the term indicates that 供 was not intended to denote children as possessions. In modern Japanese, 子供 can refer to either a single child or multiple children without explicitly implying ownership.

Until recently, government documents typically used 子供, and in 2013 the education ministry instructed its staff to standardize on this kanji spelling. Media outlets have varied in their usage based on house style, often alternating between 子供 and 子ども. This variance contributed to all three forms being familiar to the public.

The terminology underwent another change following the establishment of the Children and Families Agency and the enactment of the Basic Act on Children in 2022. With the official launch of the agency in 2023, the government adopted the hiragana spelling こども within its name—こども家庭庁 (Kodomo Katei-chô)—signaling an intentional move towards more approachable and neutral language in child-related policy documents.

This shift reflects an ongoing effort to balance linguistic tradition with evolving social sensitivities regarding how children are referenced in Japanese society.
