'''NOTE: This page is based on the anime adaptation of the series. DO NOT PUT MANGA SPOILERS!'''

Tadashi Yamaguchi (山口 忠, Yamaguchi Tadashi) is one of the supporting protagonists in Haikyuu!! He is also one of the four first-years of Karasuno High who is the pinch server and the middle blocker of the boys' volleyball team. Prior to his interest in playing sports, he was bullied by a group of boys during elementary school for his freckles and scrawny appearance until he was saved by Tsukishima Kei. The other day, Tsukishima noticed that Yamaguchi wanted to join the volleyball club, considering that it is more of a safer choice than soccer and basketball. Since then, Yamaguchi becomes attached to his new best friend, Tsukishima and later ends up having the same class as him at Karasuno High.

The Only Bad Quality

 * 1) Despite his generally kind nature, he occasionally teases others with Tsukishima (whose personality is the opposite of the former's).

Trivia

 * His first name means "loyalty" and "devotion" (忠), which best describes his personality regarding his relationship with Tsukishima.
