>These toilets, known as “washlets”, have many amazing features - the most notable of which is they render toilet paper obsolete.

Uh, no they don't. And if the author is using them that way, that's fucking gross. If they rendered toilet paper obsolete then Japanese bathrooms wouldn't have toilet paper, or Japanese wouldn't use it anyway, but neither statement is true. The 'feature' of Japanese toilets is that your asshole will be clean, regardless of how dire the shit you just took is. And believe me, it's a wonderful thing, but it doesn't render the paper obsolete.

Pardon the pun, but this author is talking out of his ass.
