A science manga originally thought to be suitable for children has suddenly become the center of controversy in Japan after a mother discovered it contains many suggestive images. The story quickly spread on social media, igniting debates about the line between education, entertainment, and age-appropriate content.
The manga at the heart of the issue is Hell Doctor Kurare no Kagaku wa Subete wo Kaiketsu Suru!, which has been published since 2018. The work is created by Yuuji Kamo with scientific content supervised by Kurare, who also advised on the science in the popular manga Dr. Stone.
The story follows a “mad scientist” who believes science can solve every problem in life, blending humor with real scientific knowledge. Because of this, many parents considered it a good choice to inspire their children’s interest in science.
However, things took a very different turn.
In a widely shared post, a mother recounted visiting a manga and light novel exhibit at a museum, where she saw the cover and thought it would be a perfect gift for her science-loving son.
But after flipping through a few pages, she immediately changed her mind upon discovering numerous scenes depicting women drawn in a suggestive style. She expressed disappointment, believing this was a work accessible to elementary school students.
The mother also shared that parents in Japan often have to personally check manga, anime, and TV shows before allowing their children to engage with them. She said this process is increasingly exhausting and hopes for solutions that help parents easily identify the suitability of each work.
The post quickly caught the attention of the online community. Many parents agreed with her viewpoint, sharing experiences of manga aimed at young audiences that still contained sensitive elements or content.
On the other hand, some readers argued that parents trying to control everything their children read is not the best solution. They believe children at different ages have varying levels of understanding, and parents should guide rather than outright ban.
Additionally, many pointed out other well-known examples like Chainsaw Man and even shoujo manga, which sometimes introduce sexual themes at an early stage.
Several netizens recommended that for truly safe science-themed works for young children, Doraemon remains a more reliable choice.
