Can we talk about breasts? Specifically, the large kind, which in the United States are affectionately (or not) called "knockers" or "hooters." In Japan, the slang is more clinical : kyonyu (giant breasts), honyu (rich breasts), and even bakunyu (explosive breasts). These words are clinical because nyu means milk, which makes these breasts sound as if they're attached to Holsteins.
Anyone who rides the subway gets a faceful of big breasts every day in the advertisements for magazines and comics. The most common image is of a very young woman in a bikini bending over toward the camera in order to emphasize the pendulous nature of her breasts, a posture that makes the comparison to udders unavoidable.
The ads have been there for years, but the competition for attention using bigger and bigger breasts seems to be increasing, and, in fact, is moving into new realms. Last week's issue of the photo-scandal magazine Flash included a feature on yunyu joshi-ana (ample-breasted female TV announcers), which follows similar features published in other weeklies.
