A typical 9-year-old boy usually spends his days immersed in school, play, and the joys of childhood.
From schoolwork to playing and hobbies, as well as making new friends and exploring creativities, boys at this tender age have their daily routines largely directed by adults—parents, teachers, and caretakers. At this stage, children are still developing their emotional intelligence, curiosity, and independence.
They're still dependent, and it's extremely rare to see them handling the stress and risk of having responsibilities.
But Ryu Kintoro managed to skip most of those childish activities, and ventured towards branding in entrepreneurship and being an online celebrity.
Ryu enters the picture through the unforgiving online world of the internet, equipped with his extraordinary skills.
Ryu Kintaro first carved a name for himself when he became a YouTuber.
Born in Indonesia and mentored by his father, Ryu began making content as early as age 5. By age 6, he had built his own content team, and uploaded videos of him unboxing and reviewing toys. By the age of 7, he started running small ventures, like selling crispy chicken from a cart and fresh milk.
These early experiments fizzled due to time constraints and perishability, but they laid the groundwork for bigger ideas. His real breakthrough came with “Tjap Nyonya Kaya,” a bottled herbal jamu drink (Indonesian herbal drink) he’d formulated to be sweet and kid‑friendly without added sugar, targeting those who disliked the traditional bitter taste.
The product quickly gained traction: priced at around Rp15,000 per bottle, it generated approximately Rp1 billion in annual revenue—an extraordinary achievement for someone still in elementary.
In parallel, Ryu’s YouTube channel skyrocketed.
Boasting over 1 million subscribers, he received YouTube’s Silver Play Button after reaching 100,000 subscribers and the Gold Play Button within a year for surpassing one million.
His content spans short-form vlogs, DIY experiments, challenges, product unboxing, and educational tidbits for kids—often shared via YouTube Shorts, which he credits for his rapid growth and viral success. During one nine-year span, a video garnered over 70 million views, cementing his presence as a digital star among Indonesian families.
As a child juggling between being an online celebrity, product lines, and content teams—it’s not just impressive, it’s extraordinary.
While Ryu certainly has adults behind him, there are all behind the scene, and Ryu literally is the brand.
In 2025, Ryu was named runner‑up in the Southeast Asia Young Entrepreneur X Factor competition, becoming the youngest finalist in a field of innovators aged 8–17.
His Tjap Nyonya Kaya venture earned recognition for blending local tradition with modern branding, earning cash awards and entry into mentoring programs and boot camps across the region.
A lot of people praise Ryu for his achievement, most notably due to his young age. But a lot of others mock him.
There are several reasons for this.
First of, Ryu is the son of Christopher Sebastian, the CEO of Makko Group, who have had a troubled past.
Sebastian was once entangled in drug abuse and criminal activity. Born in Surabaya, he left formal education early and never applying for a job using his high school diploma, and began working in unlikely roles—first in advertising at a subsidiary of PT Gudang Garam and later in distribution for hotel supplies.
But then he fell into the shadows of addiction and became both a drug and gambling dealer following the emotional trauma of his parents’ divorce. He was arrested and incarcerated twice.
After hitting rock bottom, he found guidance and redemption through rehabilitation, where his spiritual mentor helped him reframe his life and pursue a brighter path.
He then reemerged to become the founder and CEO of Makko Group, a major automotive accessories and food conglomerate in Indonesia.
Christopher Sebastian’s life reads like a dramatic turnaround story.
Based on this, then came the second reason: Ryu was born into privilege, meaning that Ryu’s family situation enabled early access to resources: his father gifted him business ventures instead of toys for his seventh birthday, coached him in time management, and supported his schooling, coaching, and content creation.
In general, most people in Indonesia who wish to become entrepreneurs are those who are either unemployed, laid off, or born from low income family and couldn't afford formal education. What this means, Ryu's story is nothing more than just a boy trying to showcase his father's wealth and influence, on behalf of the family.
One of example of this is clearly shown in one of Ryu's most viewed YouTube Shorts videos, where he can be seen selling jamu from a Lexus.
In other words, critics argue that Ryu had it easier than most.
Harsh comments escalate when Ryu Kintaro started offering an exclusive e‑book titled “Cara Mendapatkan 100 Juta Pertama di Usia 8 Tahun” (“How to Earn Your First 100 Million in Rupiah by Age 8”).
In it, he shares his journey—from making videos on his parents' phones to building a content team, launching viral campaigns like selling jamu, and hitting financial milestones before turning nine. The e‑book covers his passion discovery, child‑safe content strategies, balancing school and creation, YouTube monetization, and branding tips.
It's marketed as a roadmap for aspiring young creators or supportive parents interested in youth entrepreneurship and digital creativity
As a result of this, a lot of social media users challenged his narrative of entrepreneurship, questioning whether a self-aware sense of risk and "hustle mindset" could be fairly attributed to a child from a wealthy family with pre-existing networks.
In other words, Ryu’s story isn’t something the average person can connect with—his path is so exceptional, so far removed from what most 9-year-olds or even adults experience, that there’s little anyone can take from it to apply to their own lives. His fame, his platform, and the resources around him form a world that feels alien to most, making his success not instructive.
Others still find Ryu admirable, and applauded his vision and performance in the competition, emphasizing the mismatch between public assumptions and individual opportunity.
Regardless, Ryu himself expresses gratitude and determination, positioning his story as inspiration.
His story tells that age isn’t a barrier to innovation and self-reliance. He also places education first, ensuring school remains a priority alongside his ambitious extracurricular endeavors.
Despite the criticism, Ryu continues to expand.
He regularly appears on Indonesian TV shows and podcasts—such as Raditya Dika’s channel—and is featured by major publications. His Instagram and TikTok content rack up millions of views, and he speaks candidly about failure and success with surprising maturity. He often shares the lesson that perseverance, curiosity, and support matter more than age or background.
YouTube Shorts remains a key outlet for his creativity, thanks to its accessibility and youth-oriented format—short vertical videos packed with relatable scenes, fun challenges, and glimpses into his business life.
Looking ahead, Ryu sets his sights on expanding his brand through collaborations, more engaging content, and business diversification. He aims to inspire other kids to dream big and work hard, positioning himself as a model of modern youth entrepreneurship. For him, success is about shaping his own path and helping others see that creative ambition knows no age limit.
In essence, Ryu Kintaro is a rare blend of digital creator, business strategist, and young motivator—caught between YouTube stardom, entrepreneurial innovation, and the scrutiny that comes from both public admiration and social media skepticism.
