A Japanese man with a passion for body modification earned a record with his exceptionally large flesh tunnels.

Nero Daikokudo has the largest conch flesh tunnel (male) after stretching the tops of his ears to a massive 3.8 cm (1.5 in).

A conch flesh tunnel is a stretched piercing in the conch, which is the middle part of the ear, through the cartilage.

Nero gradually increased the size of the piercing by using larger jewellery.

In our video, he’s seen taking the 3.4 cm tunnels out of his ears to replace them with 3.8 cm ones.

He first pushes a plug through the tunnel to help stretch his skin enough to get his new jewellery in place.

After using digital callipers to get precise measurement of his flesh tunnels, Nero officially earned himself the world record.

He describes himself on Instagram as an artist, model and “cultural icon in progress”.

He’s amassed a large following of over 23,000 people with his unique look and perspective on life.

Almost all of Nero’s body is covered in tattoos.

In nude pictures posted to his Instagram account, you can see that he has blacked out most of his body with ink, sparing his knees, elbows, and parts of his hands and feet to create a pattern.

His face is also an exception, with red ink framing his features.

Nero certainly knows how to pose for a striking picture.

From catwalk struts to transforming into fantastical characters, Nero looks incredible in every single one of his pictures.

It’s clear he’s a man who's not afraid to embrace his uniqueness.

And his fans appreciate it.

One commented on a snap: “You look so cool”.

While another wondered: “Wow I wonder how long that tattoo took! Must have been weeks?”

“You’re the coolest ever,” a third posted.

And one admirer told him: “Always on! Giving visual life to this earth”.
