A Japanese man proved that porn can be really, really bad for you — when his dead body was found six months after his 6-ton collection of filthy mags toppled on top of him.

The 50-year-old smut aficionado’s corpse was discovered after the landlord entered his apartment because he had fallen behind on his rent, the Mirror of the UK reported.

A member of a cleaning crew hired to quietly remove the horny hoarder’s stash said he found the former carmaker, identified only as Joji, buried under a massive pile of porn.

The cleaner, who said Joji may have suffered a heart attack, had filled every nook and cranny in his joint with the magazines and clippings of his favorite sections.
