One of the most beloved Japanology memes overseas involves the word kaizen (or Kaizen to some). Here's the definition from the New Oxford American Dictionary:

kaizen |ˈkaɪzən|
noun: a Japanese business philosophy of continuous improvement of working practices, personal efficiency, etc.

That sometimes gets further embellished by eager writers who extend kaizen to carry continuous improvement out of the business realm, and "throughout all aspects of life", per one definition I've seen. Whatever the specifics, what you'll find in common across all definitions is that kaizen is a Japanese word for "a Japanese philosophy of continuous improvement".

Unfortunately, that's wrong. Read more about Debunked: "kaizen = Japanese philosophy of continuous improvement"

CRACKED Magazine offers a scatalogical look at Japan's Insane Creation Myths. "Hoo boy", I thought, "here comes another bunch of wild exaggerations to play up the 'Japan is so crazy' meme".

Well... I'll leave specific criticisms to experts in the field, but a scan of the linked references suggests that, yeah, these myths are built from the distilled essence of porn movies and junior-high body function jokes. Which isn't unique to the ancient myths of Japan, as many commenters point out, but these particular myths sure do aim for the gutter.

Like zillions of people, I'm a big fan of Pharyngula. It's a blog by scientist and outspoken atheist P.Z. Myers, straddling both science and (ir)rationality as its topics.

What do witty, learned discussions of science and religion have to do with Home Japan, a lowly blog about cultural matters? The big item in common: critical thinking. Skepticism and rationality, if you will – the best tools we have for clearing away preconceptions and errors and what not, and getting at the reality. I'm simply trying to take those same approaches and tools into cultural comparison, a field I feel they've had little contact with. Read more about Skepticism and cultural comparison

In discussions of culture, why do so many people favor extreme, polarized claims over reality?

It's a common happening, though here I write after coming across a very minor example. I happened across a report on a designer's stunning blend of traditional kimono and African fabrics – the Wafrica kimono. The results are beautiful, and I can appreciate the creator's thought (unless I'm misreading) that the end result is its own object, not a subcategory of arbitrarily-labeled cultures: Read more about Why the need for extremes?

If you haven't read Debunked: Japan's "Special Relationship with Robots", please do. All humility aside, that article is a good example of a culturology meme that persists despite overwhelming evidence contrary to its claim (and really no evidence supporting its claim).
