Approx translation:

> The grievous rape of a white woman

> A mother of two enjoying married life.
> She and her family are tourists.
> Their mistake; choosing a hotel run by the Yakuza.
> The hidden camera in the bathroom observed all.
> A beautiful face, a voluptuous body and breasts.

> Tomorrow, when her family is distracted, she'll be taken,
> and her new life as a sex slave for the Yakuze to rape will commence.

> An innocent life, changed forever.
