もや

• Reading: もや
• Romaji: moya
• Kanji breakdown: 靄 (ai) — mist, haze (the kanji is rarely used; もや is standard in modern writing)
• Pronunciation: /mo.ja/

Meaning

Mist; haze; a thin atmospheric obscuration that reduces visibility without reaching the density of fog. Lighter and more diffuse than 霧.

A yamato kotoba noun typically written in hiragana in modern usage, though the kanji 靄 exists. もや describes a soft, diffuse atmospheric condition — thinner than 霧 (fog) and carrying a gentle, atmospheric quality often exploited in literary description. In meteorology, visibility in もや typically exceeds 1 km. In poetry and prose, it is associated with morning, rivers, mountains, and a sense of beautiful uncertainty.

Examples

1. 夜明け前の川面には薄いもやが漂い、幻想的な風景を作り出していた。 Before dawn, a thin mist drifted over the surface of the river, creating an otherworldly scene.
2. 梅雨の季節になると、山の稜線にもやがかかり、墨絵のような景色が広がる。 When the rainy season arrives, haze settles over the mountain ridges, spreading a landscape like an ink-wash painting.
3. 工場の排煙と湿気が混ざり合ったもやが、朝の街を白く覆っていた。 A haze of factory smoke and humidity blended together, blanketing the morning city in white.
