Appearance
Before showing that he wore a mask, he didn't look very unusual, aside from some facial markings.

After he revealed this, his eyes' colors invert, his hair is more tucked into his hat and his ears become exaggeratedly large. The mask's opening also suddenly becomes visible around his neck.

Personality
Initially, Kanedaichi showed himself not to be above trickery, as he tricked Josuke Higashikata into entering Super Fly while he himself plotted a means of escape.

As he was anticipating his death, he was prepared to accept it, though had a change of heart upon being saved by Josuke and willingly lives a peaceful life in the tower, interacting with tourists casually.

His real name and appearance are unknown, as he wears a mask and everything he said about himself was part of a trick.

Abilities
Bound to his transmission tower, Kanedaichi's Stand is Super Fly; bringing it to a sort of life while trapping him inside.

After living in his tower for so long, Kanedaichi has developed huge calluses on his palms, allowing him to hammer nails, slide down a cable, aid him in calculations, and hide tools.

He is also highly acrobatic, able to swing around the telephone tower to dodge strikes with ease.

Diamond is Unbreakable
Kanedaichi is introduced as a hermit living a lonesome life in an old, retired transmission tower for 3 years. He claims to have bought it and living in there since then. He was actually trapped within it by his own Stand Super Fly and had built a home while preparing to escape. He acted peaceful so Josuke Higashikata would enter his tower without worrying about an enemy Stand. He did however live there for a long time, as he grew calluses thick and strong enough to support his weight, open bottles and a variety of things.

He fought Josuke, Okuyasu Nijimura and Mikitaka Hazekura, but decides to stay in the tower after being defeated. He becomes a Morioh landmark, letting tourists take his picture with them for spices and tools.

Toyohiro continued to live in the iron tower. Becoming an attraction in Morioh, he maintains contact with the outside world talking with tourist, who often go to chat and bring him condiments and sweets. His name is still unknown, so people call him the "Iron Tower Man". Chiho Futaba doubted the story, but then heard that there are more bizarre stories in Morioh, such as that of a girl who lived between two buildings.
