Branding the popular anime as borderline "pornography," Indonesia's television regulator has warned a broadcaster to censor "indecent" images on Crayon Shin-chan or air the series at a later time, when it's unlikely to be seen by children.

Based on the manga by the late Yoshito Usui, Crayon Shin-chan follows a the adventures of a mischievous 5-year-old who's prone to inappropriate behavior -- he frequently moons other characters -- and off-color language. Scantily clad women and risque humor are staples of the series; there's also the matter of his infamous "Mr. Elephant" dance.

That's too much for the Indonesian Broadcasting Commission (KPI), a government-sanctioned but independent regulatory body, which on Monday issued the warning to the Jakarta-based RCTI television network.

“The character Shin-chan fools around with his bare bottom exposed,” Agatha Lily, a senior official at KPI, told Japan's Asahi Shimbun. “He also noses around people on dates. The show features a lot of female characters in seductive garments that emphasize cleavage. It’s essentially pornography."

According to The Japan Times, KPI issued a similar warning to RCTI in 2011, leading the network to suspend the series and censor some of its elements. However, this time RCTI seems to be standing firm. “I don’t see what the problem is,” a spokesperson told The Asahi Shimbun. “We will continue to air the show as we have.”

Airing since 2000 in Indonesia, Crayon Shin-chan was pulled from the air in India in 2008 following government objections to language and nudity. The series has also run into trouble with censors in Vietnam and South Korea.
