Born with a typical chin, Jonouchi's began to grow pointed and elongated from the age of 5. He is the only one in his family with this characteristic.
The chin made him the target of teasing and comparisons to anime characters. Jonouchi had his chin X-rayed, revealing an unusual bone structure, but the exact cause remains unknown.
Doctors ruled out excessive milk consumption and resulting calcium surplus leading to bone deformation. They also hypothesized about mewing (the habit of resting the tongue low in the mouth) as a possible factor influencing jaw shape. This information has garnered attention from fans and experts alike.

While his chin led to romantic rejections, it also attracted a large following on social media, transforming the shy, withdrawn young man's life.
He first gained attention when his unusually long chin drew comparisons to exaggerated manga characters. This attracted the anime community, contributing to the spread of Japanese culture.
Curiosity intensified after he posted his X-ray image in a viral video, attracting interest from both experts and followers.
Jonouchi currently has about 750,000 followers across social media platforms, including 348,000 to 350,000 YouTube subscribers, 410,000 TikTok followers, and 55,000 on Instagram.
He has leveraged this difference to build his personal brand. He released T-shirts printed with "Certified World’s Longest Chin", produces comedy videos, and shares his story of overcoming self-consciousness. This has enabled him to build an online career, earning money from advertising, brand collaborations, and merchandise sales.
His case has been compared to that of Shogo Yoshida, a hairstylist once teased for his marble-like fingertips.
Instead of hiding them, Shogo turned this feature into his personal trademark, attracting over 200,000 followers on Instagram and TikTok. His videos, from hair tutorials to comedic content like using his fingers to "measure" hair or create unusual styles, have gone viral.
"My difference is my strength," he said. Shogo has not only built an online career but also launched his own hair gel line, which has become popular.
