グングン

• Reading: グングン
• Romaji: gun gun
• Pronunciation: /ɡɯŋ.ɡɯɴ/

Meaning

Steadily and powerfully advancing, growing, or accelerating — progress with unstoppable momentum.

グングン conveys powerful forward momentum — something growing, advancing, or improving with relentless force. Unlike メキメキ which emphasizes noticeable skill improvement, グングン focuses on the continuous, unstoppable nature of the progress. It's used for plants growing tall, temperatures rising, a runner pulling ahead, or someone's abilities snowballing. It carries an energetic, dynamic feeling.

Examples

1. 気温がグングン上がって真夏日になった。 The temperature kept climbing and it turned into a scorching hot day.
2. 子供ってグングン背が伸びるよね。 Kids grow so fast, don't they?
3. 後半からグングン追い上げて逆転勝ちした。 They surged from behind in the second half and pulled off a comeback win.

Don't Say

• 停滞してる状況に「グングン」は矛盾 (Using 'gun gun' for a stagnant situation is contradictory — it implies strong forward momentum)

Common Mistakes
