A dance school with ~1,500 members was handed off after screening dozens of candidates. The turning point was "the results of a cancer screening"

Why give up a business you built from scratch into roughly 1,500 members? For Ayaka Saito, founder of Carnelian Inc., the answer was neither performance nor cash flow. It was the result of a cancer screening.

Carnelian is a school centered in Tokyo that offers dance lessons for adult beginners, with roughly 1,500 members. Saito launched the business at age 25 with 500,000 yen in capital. Then in 2020, a diagnosis of high-grade dysplasia from a cancer screening became the turning point that led her to hand over the business. The buyer was an individual with no experience running a dance school. The amount was undisclosed.

From founding to succession

Class design built around “who you want to become”

Carnelian’s distinctiveness lies in how it structures its classes. Most dance schools organize classes by genre — hip-hop, jazz, ballet. Carnelian dropped that and instead built classes around “the image you want to become.” Musical, anime song dance, club debut, K-pop. The axis is the image students envision for themselves. The stated concept is “dance and have fun becoming the self you want to be.”

This design maps precisely onto Saito’s own career. She danced to the level of appearing on TV as a professional backup dancer, but along the way came to doubt the industry atmosphere that treated “dancing well” as absolute justice, and drifted away from dance when she entered university. She has said she came to realize she didn’t actually like dancing. That it felt painful.

Then, after giving birth, her perception flipped at a beginner workshop she attended amid poor health and the absence of any mom friends. Dance could be more than a competition of skill. It could be a means of socializing and refreshment. Someone who had once thought “beginner lessons, please” came to know that value firsthand.

This is where the structure works. A person who knew the world of advanced dancers deliberately discarded the advanced-dancer evaluation axis when designing the classes. Classify by genre name, and beginners who can’t judge “which genre suits me” get stuck at the entrance. Classify by “the image you want to become,” and even someone with zero dance experience can choose their own destination. Her professional experience was used not for the quality of instruction but as the ability to articulate exactly where beginners stumble.

The turning point was clear — the 2020 diagnosis

The turning point in this case is easy to pinpoint: the 2020 cancer screening.

That was the first time Saito became conscious of “death.” And what she thought about wasn’t only her own body. “If I’m gone, Carnelian will disappear too.” A business with about 1,500 members was tied to the health of a single founder. Facing that fact pushed succession from an abstract idea into a real agenda item.

Afterward, Saito enrolled in the University of Tokyo’s death studies research lab. The sequence was that she decided on business succession in order to commit fully to research. The motive for succession, then, was not “withdrawal” but “movement.” Illness was the trigger, but the destination was research, not recuperation.

That said, how membership numbers or revenue changed before and after succession has not been disclosed. What can be traced in this case is the decision-making process, not the trajectory of the numbers, and that line is worth drawing honestly.

How the buyer was chosen — “not a profit-driven type”

Saito negotiated with dozens of candidates. That sheer number of candidates is itself one success factor. She set her top condition for the buyer as “someone who can provide better service to students and staff,” without regard to whether they were a company or an individual. However, sympathy with Carnelian’s vision was a non-negotiable requirement.

The person chosen, Mr. Furukawa, is a sole proprietor working in management consulting, with no experience running a dance school. Three things decided it: that he himself genuinely liked dance. That he took both school operations and business seriously. And that he showed a thoughtfulness that wasn’t profit-driven.

She chose based on values rather than industry experience. This might look like an irrational decision, but given that Carnelian’s competitive strength comes from “a design philosophy that doesn’t intimidate beginners,” it’s logically consistent. The moment efficiency is prioritized and the school tilts toward higher-margin classes for advanced dancers, this business’s distinctiveness is lost. When the asset that must be protected isn’t a physical thing but a design philosophy, a buyer’s values carry the same weight as financial terms.

Saito describes Carnelian as “feeling like a daughter I raised.” The effort of meeting dozens of people to choose one aligns with that sense.

What can and can’t be replicated

A succession elsewhere can reuse the same choices: casting a wide net before narrowing down candidates, defining selection criteria not by “industry experience” but by “can they protect the philosophy at the core of the business,” and handing over management in phases. At Carnelian, the phased transfer continues after succession, running in parallel with DX of the systems and a strategy for recruiting new students, starting from the areas where the buyer’s consulting experience is useful.

What can’t be replicated is equally clear. The professional backup-dancer career, the discomfort she felt toward the industry along the way, and the experience of joining a beginner workshop as a beginner herself after giving birth, only when all three overlap does that kind of class design emerge. Copying only the “classify by desired image” surface, after the fact, without being able to articulate beginners’ psychology at high resolution, produces just an empty shell.

And the condition least worth replicating is the trigger for succession itself. Saito has said, “Rather than struggling alone, expanding possibilities by having various people help you,” positioning M&A as a means of securing support during hard times. Whether you can treat the very state of a business being tied to a single founder as an ordinary-times risk, rather than starting to search only after a health scare, is the single point this case puts to us.
