As usual, I was trying to extrapolate the Japanese identity through a popular subculture when I happened upon the following pic from Keroro Gunsou.
This is particularly interesting since the main character of Densha Otoko is a fan of Keroro Gunsou. Given the amount of devotion he has to this series, such subtle messages only cause people of his disposition to further shun society. To insinuate a negative point of view into something as innocent as a clothing department store goes beyond the moral and ethical boundaries for animators in Japan.
While the moral dilemmas faced by animators of invader frogs from outer space may seem esoteric to some, a more relevant social issue can be found in Futakoi.
The issue of “submarining” regarding seatbelts, tends to be a topic under the radar of most people who watch shows that have pre-pubescent twins. Serious injury can result from the ill-fitting safety belts, and I’m surprised that references to this topic are quite lacking in anime.
