Idiomatic expression; the kanji 金玉 is a colloquial term for testicles. Rare overall.
Variant using the anatomical term 睾丸 for testicles; less common than 金玉.
From the folkloric image of a raccoon dog (tanuki) with large testicles, humorously exaggerated to cover eight tatami mats. The exact origin is uncertain, but it plays on the tanuki's legendary association with oversized scrotums in Japanese folklore.
