Description
Mitsuyoshi Anzai serves as the head coach of the Shohoku High School basketball team and is widely recognized as one of the most respected coaches in Japan, often addressed as Anzai-sensei even by rival coaches. His outward appearance is that of a gentle, heavyset man with white hair and glasses, presenting a calm and collected demeanor on the bench. This placid exterior, however, belies a complex history and a sharp strategic mind.

Anzai sensei was not always the patient mentor seen in the series. In his earlier years as a demanding college coach, he was known by the fearsome nickname White-Haired Devil due to his strict and abrasive training methods. This all changed following the tragic death of a talented player he had coached, Ryuji Yazawa. Frustrated by Anzai's relentless focus on fundamentals, Yazawa had defied his coach's wishes and moved to the United States, only to die in a car accident years later while reportedly under the influence of drugs. The deep grief and regret Anzai felt over this loss, compounded by a letter from Yazawa expressing profound remorse for his rebellious decision, led to a complete transformation in his coaching philosophy. He resigned from college coaching and reinvented himself, earning the new nickname White-Haired Buddha for his subsequent mild temper and supportive nature.

Behind this impassive and tolerant facade lies a brilliant strategist who consistently demonstrates an ability to turn the tide of a match. Anzai sensei possesses a keen eye for raw talent and potential, which he nurtures with great care. He was one of the first to recognize the untapped abilities of the impulsive rookie Hanamichi Sakuragi, opting to make him a starter early on and providing him with crucial personalized training, such as the grueling regimen of making 20,000 jump shots in a week to prepare for the national tournament. His motivational skills are legendary; he is a charismatic figure capable of inspiring players to reach greater heights. His words gave Hisashi Mitsui the confidence to never give up during a crucial middle school game, which is why Mitsui chose to attend Shohoku specifically to play under Anzai. Similarly, he has been shown to calm the insecurities of players like Ryota Miyagi and inspire the talented but solitary Kaede Rukawa.

Anzai sensei's key relationships with his players are defined by his patient guidance. While Sakuragi frequently and disrespectfully calls him Oyaji (old man) and playfully jiggles his chin, Anzai tolerates this behavior without reprimand, understanding the boy's nature. His most profound bond is arguably with Mitsui, who holds him in such high regard that he once placed a picture of the coach on the bench and prayed to it when Anzai was hospitalized with a heart attack. Although he rarely shows intense emotion, the fire of his competitive youth has not entirely died, and coaching a new generation of talented players like Sakuragi and Rukawa has reignited his passion for the game. His development throughout the story is one of quiet reinforcement of his new philosophy: that a coach's primary role is to foster growth and confidence, creating not just skilled players, but a cohesive and determined team. In the specific film Slam Dunk: Zenkoku Seiha da! Sakuragi Hanamichi, this coaching wisdom is put to the test as he faces a former student who is now the coach of the opposing team, Tsukubu, adding a personal layer to the high-stakes competition.
