Kokou no Hito

On his first day of transferring to a new high school, a loner named Mori Buntarou, is cajoled by a classmate into climbing the school building. Despite knowing that one misstep could send him spiraling to his death, he moves forward, and upon finally reaching the top, Mori experiences a sense of fulfillment. That feeling, which seems to be telling him, "You're alive!" gives birth to an adrenaline for rock-climbing.

The series tells the story of introverted solo mountain climber Mori Buntarō—partially based on real-life mountain climber Buntarō Katō—who is introduced to sport climbing after being transferred to a new high school and later dedicates his entire life to professional mountain climbing, with the ascent of K2's East Face as his ultimate goal.

In 2010, The Climber won an Excellence Prize at the 14th Japan Media Arts Festival.
