Masahiro Hashimoto

Masahiro Hashimoto is a short man with closely cropped hair and sun-tanned skin.

He always looks cheerful and approachable.

In the TV series, he appears with a scruffy beard and glasses, clearly showing he’s an adult.

When he visits Kitauji High, he shows up wearing flashy, colorful shirts and shorts, looking very casual.

His wild fashion sense often surprises the students, who joke about his lack of style.

Hashimoto always greets people with a big, friendly smile and has a loud, booming laugh.

He’s lively and knows exactly how to put others at ease.

He is a master at making people comfortable and building trust quickly.

When he laughs or throws his hands back in exaggeration, he can make any stressful situation feel lighter.

Hashimoto is clever—he is open and friendly, but he keeps his guard up when it matters.

He uses his friendly nature as a tool to help students get the most out of their training.

Kumiko Oumae’s classmate Kanade Hisaishi once called him “very skilled at seeming open while staying guarded himself.”

Voice actor Yuichi Nakamura, who voices Hashimoto in the anime, says he played him as outgoing yet gentle, thinking of him as an "O type" personality: easygoing but also serious.

Nakamura also tried to show Hashimoto more as a friendly partner to the students, not just a strict teacher, but he knew when to get serious.

Hashimoto is a professional percussionist who has played with groups both in Japan and overseas.

He is also known as an expert coach.

He helps different school bands, offering detailed and specialized lessons, especially with percussion instruments.

His advice greatly improves the students' skills.

Noboru Taki, the director, trusts his guidance completely and calls his teaching “top class.”

He gives tips on how to play each percussion instrument better, such as snare drum, timpani, xylophone, and cymbals.

Hashimoto also helps arrange the layout of instruments during big performances and comments on the balance and tuning of the entire band.

He strongly advises the students: “The first note sets the tone for the whole concert. Don’t make mistakes at the start.”

Hashimoto believes music is about enjoying yourself, not just winning prizes.

He always reminds students: “Music means enjoying sound. Don’t get stuck focusing only on awards.”

He wants every student to become a true musician, not just someone who plays for results.

For him, the most important thing is expressing your feelings in music and having fun on stage.

He also talks openly with directors like Noboru Taki, reminding them not to force students to only care about competition results, but to let them make music they love.

Hashimoto was a member of the Kitauji High School concert band during its "golden era."

He was coached by Noboru Taki’s father and helped the band reach the nationwide finals three times.

After high school, he went to the same music college as his classmate Chihiro and met Noboru Taki and Satomi Niiyama there.

While Taki and Chihiro became teachers, Hashimoto chose to become a pro musician.

He stayed in touch with them after graduation.

When Chihiro, who later married Taki, passed away, Hashimoto and Niiyama wanted to comfort Taki but didn’t know how.

They quietly supported him from afar.

Later, when Taki became the band director at Kitauji and asked Hashimoto to help coach the students, Hashimoto was deeply moved and happily agreed, feeling a sense of trust and destiny.

Noboru Taki

Hashimoto and Taki have been close friends since college.

Hashimoto calls him “Taki-kun,” and Taki calls him “Hashimoto-sensei.”

Their personalities are opposite—Hashimoto is a people person, while Taki is more logical—but they get along perfectly.

Hashimoto is always looking out for Taki, making sure he doesn’t carry too much stress alone, and sometimes even forces him to eat when he forgets.

When Hashimoto pushes his luck too far, Taki puts him in his place, but they both laugh it off, showing their deep trust.

Hashimoto also respects Taki’s leadership skills and calls him “someone people naturally follow.”

Satomi Niiyama

Hashimoto and Niiyama are old friends from music college.

Niiyama is younger, but they played together in the university orchestra.

Hashimoto helps Niiyama understand Taki better, keeping everyone connected.

They stay in touch, and Hashimoto even hears about Niiyama’s marriage as an adult.

Chihiro Taki

Chihiro was Hashimoto’s classmate at Kitauji High and at music college.

They shared memories of their school years and loved talking about old times.

When Chihiro married Taki and later passed away, Hashimoto was so saddened that he couldn't face Taki directly for a while.

Michie Matsumoto

Hashimoto meets Michie Matsumoto, the Kitauji band’s assistant director, when he is invited as a coach.

They become friendly, sharing laughs and stories at teachers-only gatherings, and sometimes end up drinking together.

There are no hints in the story about whether Hashimoto and Michie knew each other from their own high school days.

Hashimoto can eat a lot! In college, he even scared Taki with how much food he ate.

He still piles up plates, like finishing three bowls of curry at band camp.

He once traveled around the world alone when he was younger.

A student once asked if he spoke English, and he joked, “I will be back!”

On Musical Expression

"Kitauji’s playing is strong enough now to stand with the best schools. But you’re missing expression."

"You need to think about what kind of music you want to create. You need more than just technique.”

On Competitions

"I’ll be honest: I’m not a big fan of competitions. I always tell kids, 'as long as you try your best, gold, silver, any medal is fine!' But the truth is, it’s not only about the results. It’s about enjoying music. If you go on stage all nervous, the audience won't feel your joy. Go up there and show your music to the world!”

On Staying True to Music

"Don’t just worry about results and evaluation. No matter what happens, keep pursuing the music you want to play. When you step on stage, you’re a true musician. Enjoy the music first and let the audience enjoy it too.”

Becoming a Coach

Noboru Taki, who knew Hashimoto from university and values his skills, invites him to help the Kitauji concert band.

Hashimoto, who used to be a star of the same band in his own school days, returns as a guest coach.

Inspiring Students

Hashimoto quickly connects with the students, teaching them both percussion skills and his philosophy about music being fun and meaningful.

He uses nicknames with the students, throws in funny stories, and isn’t afraid to be strict when needed.

He helps the percussion players master their parts and also advises the whole band for better balance and sound.

Facing Competition Pressure

As the band prepares for big competitions, Hashimoto encourages both the students and Taki to care about more than just medals.

He supports them during tough times, like when the band almost falls apart before the nationals.

He tells Taki, “This is your true test,” supporting him with advice and friendship.

The Big Performance in Okinawa

In his third year coaching, Hashimoto receives a request from an old friend: Kitauji’s band is invited to play at a theme park opening in Okinawa.

He proposes it as a "graduation trip" for the outgoing third years.

He conducts the older students in a special mini-concert and gives them a heartfelt message: “I want you to enjoy playing, not just play well.”

Hashimoto played an important role in helping connect different generations of Kitauji High’s band, combining his skills as a performer and teacher.

He always encouraged students and teachers to value the meaning of music and to treasure their own growth as musicians.
