Memorial Stone

The memorial stone is a monument in Konoha 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 remarked that he wanted to have his name added to the monument, Kakashi 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 team-mate, Obito Uchiha's, name is engraved there. Hayate Gekkō and Iruka's parents' names are also listed.

Trivia

 * In the movie Naruto Shippūden 3: Inheritors of the Will of Fire, the Memorial Stone was depicted in a similar fashion to its manga form.
