Nasal が (鼻濁音): The Soft “ng” Sound That Makes You Sound Native

Normally が is a hard [g], like the “g” in “go”. In 鼻濁音, that [g] turns into the nasal [ŋ] — the “ng” at the end of English “sing” — but at the start of the syllable: nga, ngi, ngu, nge, ngo.

The air goes through your nose instead of bursting from the mouth, giving a softer, gentler sound that flows better inside a word.

The traditional pattern is simple:

• Start of a word → hard [g]: 学校 (がっこう), 銀行 (ぎんこう).
• Inside or across a word → nasal [ŋ]: 中学 (ちゅうŋく), 小学校 (しょうŋっこう).
• The particle が → nasal [ŋ]: 私が… is traditionally nasalized.

Numbers and tightly-bound compounds have exceptions, but “hard at the start, nasal in the middle” covers the core.

I won’t pretend otherwise: 鼻濁音 is on its way out. A lot of younger Tokyo speakers use a hard [g] everywhere now, and nobody misunderstands them. These days it lives mostly in broadcasting, classical singing, and the speech of older generations.

You’ll still run into it, especially in formal audio, so it’s worth recognizing. But no one is going to mark you down for using a hard が all the way through.
