Masashi Yamada was a teacher who arrived for the Onion Alien Mission.


Masashi Yamada is a male in his early to mid-30’s. Due to his profession, he dresses formally; a dark suit, black pants a white shirt and a tie. He also wears glasses and a pair of dark shoes.


Yamada is a very sociable person. Encouraging others to introduce themselves and he takes the initiative and starts doing so.


He taught first graders at Nerima Elementary school. He died on his motor scooter in an accident and was then transferred into the Gantz room.


Onion Alien MissionEdit

He appeared in the room before the Onion Alien mission and asked the others to introduce themselves with their names and stories. He was skeptical of the idea that everyone in the room was dead, and came up with the notion that the whole thing was part of a TV show with hidden cameras.

Yamada died during that first mission after having both his arms cut off by the boss alien. While dying, he dreamed that it was all a fake TV show, and that everyone was still alive and well. However, he soon woke up and screamed in horror when he saw his arms were gone. He then bled to death, still clinging on to the hope that he'd be transferred back to the Gantz room.

Tanaka Alien Mission ArcEdit

Abilities and PowersEdit



  • In the anime, all mentions of his speculations on the Gantz room being a TV show are removed. Also, Nishi never tells him about it actually being a TV show, since his story in the anime was changed to him being the son of "Vice-Minister Nishi" and that the aliens and guns were all real.
  • He was the one who accidentally killed Hatanaka in the anime due to panicking. In the manga, it was Inamori who shot first.
  • Another difference is that his delusion of being perfectly fine after the alien cuts off his arms is not present in the anime, so he dies immediately afterwards instead of saying that he wants to go back to the room.
  • In hbi2k's Gantz: the Abridged Series, his name is Joe Salaryman. And he is very well received and liked by all.
