Known for his confidence, sharp wit, and unconventional storytelling style, Karashi quickly became a fan favorite after making his anime debut. His modern approach to rakugo and his rivalry with protagonist Akane Osaki have made him one of the most talked-about characters in the series.
But who exactly is Karashi Nerimaya? Is he based on a real-life rakugo performer? And who voices him in the anime?
Here’s everything you need to know about Karashi Nerimaya from Akane Banashi.
What Is Akane Banashi About?
Before diving into Karashi’s character, it’s helpful to understand the world of Akane Banashi.
The series follows Akane Osaki, the daughter of a rakugo performer whose career was devastated after a controversial promotion examination. Inspired by her father’s passion and determined to prove herself, Akane sets out to become a professional rakugo storyteller.
As she trains under experienced masters and faces increasingly talented rivals, Akane discovers both the beauty and harsh reality of the traditional performing art.
Created by Yuki Suenaga and illustrated by Takamasa Moue, Akane Banashi quickly gained critical acclaim, earning top rankings in several major manga awards before receiving its anime adaptation.
The TV anime premiered in April 2026 and has introduced a wider audience to the fascinating world of rakugo.
Karashi Nerimaya’s Profile
Basic Information
Name: Karashi Nerimaya
Occupation: University Student / Rakugo Performer
Birthday: June 18
Height: 190 cm
Age: Approximately 21–22 at his first appearance
Nickname: Genius of Student Rakugo
Karashi is a fourth-year university student and a dominant force in the student rakugo scene.
By the time he appears in the story, he has already won the prestigious Karaku Cup twice consecutively, making him one of the strongest competitors in the tournament.
Many characters view him as the favorite to win again when Akane enters the competition.
When Does Karashi First Appear?
Karashi makes his first appearance:
- Anime: Episode 7
- Manga: Chapter 16 (Volume 2)
His entrance immediately leaves an impression because of his relaxed confidence and unique personality.
Unlike many rivals who rely on intimidation, Karashi approaches everything with an easygoing attitude that often hides just how talented he really is.
A Modern Rakugo Performer With a Different Philosophy
One of the most interesting aspects of Karashi’s character is his philosophy regarding rakugo.
While many performers focus on preserving tradition, Karashi believes that the primary purpose of rakugo is simple:
“If people laugh, it works.”
This perspective sometimes puts him at odds with more traditional performers.
Rather than faithfully performing classic stories, he frequently modernizes them to appeal to younger audiences.
His approach reflects broader conversations within the real-world rakugo community about balancing tradition with innovation.
This makes Karashi more than just a rival character—he represents a different vision for the future of the art form.
Why Is Karashi So Popular?
1. His Unshakable Confidence
Karashi firmly believes in himself.
One of his most memorable statements is:
“There is no greater buff in life than self-esteem.”
This confidence isn’t portrayed as arrogance but as a genuine belief that trusting yourself is essential for success.
His self-assured attitude often contrasts sharply with Akane’s more emotional journey, creating an engaging dynamic between the two.
2. His Unique Sense of Humor
Karashi frequently gives unusual nicknames to other competitors.
For example:
- Hikaru Kouragi becomes “Voice Actor-chan”
- Akane becomes “Jugemu-chan”
These playful nicknames showcase his teasing personality and add humor to his interactions.
3. His Efficiency and Intelligence
Karashi excels not only in rakugo but also in everyday life.
According to the series, he receives recruitment offers from major companies and effortlessly handles most challenges that come his way.
This combination of talent and composure contributes to his reputation as a genius.
Karashi’s Signature Rakugo Performance: “BM”
Perhaps Karashi’s most memorable performance is his adapted rakugo story titled “BM.”
What Is “BM”?
“BM” is a modern reinterpretation of the classic rakugo story “Tenshiki.”
Rather than presenting the traditional version, Karashi updates the setting and humor to make it more relatable to contemporary audiences.
The story revolves around a graduate student pretending to understand the meaning of “BM” despite having no idea what it actually means.
As the confusion escalates, the audience is drawn into an increasingly ridiculous series of misunderstandings.
Why Was “BM” Important?
Karashi’s performance received the biggest laughs during the Karaku Cup finals.
Even judges who personally didn’t find it funny acknowledged its effectiveness with the target audience.
His performance highlights one of the central themes of Akane Banashi:
Should rakugo prioritize preserving tradition, or should it evolve with the times?
Karashi’s success demonstrates the power of adaptation and innovation.
Who Voices Karashi Nerimaya?
Karashi is voiced by Takuya Eguchi, one of Japan’s most popular voice actors.
About Takuya Eguchi
Born in Ibaraki Prefecture, Eguchi entered the voice acting industry after becoming interested in radio programs featuring voice actors.
He moved to Tokyo, attended voice acting school, and worked various jobs while pursuing his dream.
His dedication paid off when he successfully debuted as a professional voice actor at a young age.

His versatile performances have made him one of the industry’s most recognizable voices.
How Did Eguchi Prepare for the Role?
Because Akane Banashi focuses heavily on rakugo performance, the cast underwent extensive preparation.
According to interviews, the voice actors spent roughly a year studying and practicing rakugo before recording sessions began.
Eguchi reportedly memorized multiple rakugo stories and even performed on stage under the supervision of rakugo expert Hayashiya Kikuhiko.
This commitment helps explain why the anime’s performances feel authentic.
What Does Takuya Eguchi Think of Karashi?
Eguchi has described Karashi using an unusual expression:
“He’s like dried squid.”
While this might sound strange, Eguchi explained that he means Karashi becomes more appealing the more time you spend with him.
At first, Karashi may seem difficult to understand.
However, as the story progresses, viewers gradually discover more layers to his personality.
This complexity is one reason many fans have grown attached to the character.
Is Karashi Based on a Real Person?
One of the most common questions among fans is whether Karashi has a real-life model.
Official Information
Series creator Yuki Suenaga has confirmed that some Akane Banashi characters were inspired by real rakugo performers.
However, no official source has identified a specific rakugo artist as the direct model for Karashi.

Many fans specifically believe his appearance resembles vocalist Ryuta Shibuya.
Although this has never been officially confirmed as a direct model, the theory remains popular.
Karashi’s Role in Akane’s Journey
Beyond being a talented rival, Karashi serves an important narrative purpose.
He challenges Akane to think differently about rakugo.
Where Akane often focuses on mastering traditional techniques, Karashi demonstrates the importance of:
- Audience engagement
- Creativity
- Adaptability
- Personal style
His presence forces both Akane and viewers to consider what makes a rakugo performance truly successful.
Final Thoughts
Karashi Nerimaya is far more than a rival character.
His combination of talent, confidence, humor, and unconventional thinking has made him one of the standout personalities in Akane Banashi.
