Memorial Stone

The Memorial Stone is a monument in Konohagakure that lists all of their ninja that were killed in action. In the manga it is shaped like a standard slab of stone, while in the anime it looks more like a kunai-shaped structure.

It is located near the Third Training Ground, where Team Hiruzen and Team 7 were known to have undertaken their first bell test. When Naruto Uzumaki remarked that he wanted to have his name added to the monument, Kakashi Hatake informed him of what it was for, prompting Naruto to change his mind. Kakashi spends much of his free time at the monument because his former comrade, Obito Uchiha's, name is engraved there.

Other known persons whose names are etched into the stone include Hayate Gekkō, Nigiri Umeboshi, as well as well as those of Iruka Umino's father, and mother.

Trivia

 * In Naruto Shippūden 3: Inheritors of the Will of Fire, the Memorial Stone was depicted in a similar fashion to its manga form.
 * In Naruto: Path of the Ninja, Mujini Anano's name is carved on the tablet as well.
 * Despite Obito's name being engraved onto the stone due to what his team-mates believed to be his assumed death, he was in truth still alive.
