The 21st of April is
Koiwai 100% Raw Milk Yogurt Day!
It's raw milk, not raw tits!
Untranslatable: the kanji for "milk" is the same as the kanji for "breasts" in Japanese, but they're usually pronounced differently.
This was the day in which it first went on sale, back in 1984!
P-please don't take the wrong idea!(That's how you say it)Freshly squeezed 100% raw tits[sic]
