Isn't there anyone who can help us?

–Kazuhiko to Sakura Ogawa, his girlfriend.

For the novel, please go to Kazuhiko Yamamoto (Novel). For the manga, please go to Kazuhiko Yamamoto (Manga).

Kazuhiko Yamamoto (山本 和彦, Yamamoto Kazuhiko) is a minor character Battle Royale.


Not much about Kazuhiko's background was known other than he was dating Sakura Ogawa; for how long is unknown. Kazuhiko seemed to be very submissive and meek compared to his girlfriend who seemed to be more in control of their relationship. He was on the basketball team. If Kazuhiko was anything like his novel and manga counterparts, then composition would've been one of his worst subjects.

Friends and Enemies[]

Kazuhiko's only known relationship was with Sakura whom he was dating for an unknown time. Of the two, Kazuhiko was the more submissive; and it's unknown if he had other friends and enemies, except for potentially his basketball teammates.

Before the Program[]

Before Kitano resigned, Class B decided to take a day off and skip school, Kazuhiko included; he attended the basketball game against Class A, and celebrated when Class B won. Kazuhiko decided to go on the class trip; while on the bus, he most likely chatted with Sakura. Kazuhiko fell asleep after breathing in a sleeping gas pumped into the bus; he was then transported to an island and fitted with an explosive collar.

Kazuhiko, along with the rest of the class, woke up in a classroom in the island’s school. Unnerved by the presence of Shogo Kawada and Kazuo Kiriyama, Kazuhiko rushed over to the window to watch a helicopter land in front of the school. Kazuhiko was shocked to see that Kitano had returned. When Kitano asked the class if they knew the BR Act law, Kazuhiko kept quiet, obviously knowing the law, but afraid to say it aloud. Kazuhiko was horrified upon seeing Masao Hayashida's corpse. When Fumiyo Fujiyoshi was killed, Kazuhiko panicked and ran for the door trying to escape before running towards the back of the classroom when the soldiers began firing. When Yoshitoki Kuninobu's collar got activated, Kazuhiko ran around the room trying to evade him.

When Sakura's name was called to get her supply pack, she lets go of Kazuhiko's hand and goes to get it. When Kazuhiko's name was called, he grabbed his school bag and ran towards the front of the room; his caught his supply bag and ran out of the school.

During the Program[]


Kazuhiko leaping off the cliff with Sakura.

Kazuhiko manages to meet up with Sakura and it is Sakura who convinces Kazuhiko to die together as he seems uneager to do so. The couple walk to a cliff, and flinch when they hear gunshots. Kazuhiko apologizes for not being helpful, but Sakura says she's happy he came with her. Sakura declares that she'll never partake in the game before throwing her school bag over the edge of the cliff. Kazuhiko kneels on the ground and voices his hope that someone might come along and save them. Sakura bends down and takes his arm, telling him that no one is coming for them; she holds onto Kazuhiko's arm and they jump off the cliff.
