Both unflattering (Wimpus Japonica) and kind of complete animated video explaining Japan’s “herbivores,” the young men (perhaps 30%?) who are eschewing sex for domesticity, fashion, and the company of other well dressed young men.
The 1 minute 30 second video covers post-Bubble austerity, a new rejection of hetero sexuality as consumption, Japan’s declining birth rate, and gender boundary crossing. (Via Mutant Frog Travelogue).
Tokyo Moe 
is that really happening in Japan,right now?
Are they talking about Otomen?
Well, the low birthrate is not only common in Japan but also in other East Asian countries. Taiwan and also South Korea have lower birthrates than Japan and their working population is already declining and the population will start to decline around 2016. And China is the first country who gets old before it gets rich.
