国宝級

• Reading: こくほうきゅう
• Romaji: kokuhō kyū
• Kanji breakdown: 国 (country) + 宝 (treasure) + 級 (class/level) → national treasure class
• Pronunciation: /ko.ku.hō.kjū/

Meaning

National treasure level — someone so precious or talented they should be designated a cultural asset.

Combines 国宝 (national treasure, Japan's highest cultural property designation) with 級 (level/class). Used as a humorous yet sincere hyperbolic compliment for someone whose talent, beauty, or character is so exceptional they deserve official preservation. Popular in fan culture for beloved idols and in casual conversation for anyone remarkably skilled.

Examples

1. あの歌声は国宝級だと思う。 I think that singing voice is national treasure level.
2. 国宝級の美貌ってこのことか。 So this is what national treasure-level beauty looks like.
3. 技術力が国宝級で尊敬する。 Their technical skill is national treasure level — I seriously respect that.
