Let’s talk about Dobuko Busujima—yeah, that’s right, Dobuko, sometimes also referred to as Dobusu Busujima—a central figure in the wildly popular anime Mr. Osomatsu. This quirky yet oddly endearing series is actually based on the classic manga Osomatsu-kun by Fujio Akatsuka, and within this chaotic world of antics and absurdity, Dobuko stands out as a breath of fresh air. He’s one of the six main characters, but more than that, he’s the eldest son of the Busujima family, which kind of sets him apart from the get-go.

Now, if you’ve watched the show, you’ll know that most of the Matsuno brothers are, well… let’s say “energetic” in the most generous sense. But Dobuko? He’s different. He brings balance. He’s often seen as the voice of reason—the calm in the storm, so to speak. Among all the chaos caused by his siblings, Dobuko remains level-headed, logical, and, dare we say, mature. He’s intelligent, composed, and let’s not forget—good-looking too. It’s no wonder fans have such a soft spot for him.

Despite being the responsible older brother type—always looking out for the others and stepping up when needed—he’s not without a mischievous side. Every now and then, Dobuko will throw in a sarcastic comment or play a little prank on his brothers. It keeps things interesting and reminds us that even the most serious guy can have a sense of humor. That said, his maturity really shines through in how he carries himself. You’ll usually see him dressed in a sleek black suit with glasses—classic, refined, and totally fitting for someone with his demeanor.

Professionally, Dobuko works as a salaryman, and he’s pretty successful at it. His dedication to structure, order, and professionalism fits perfectly with his role in the corporate world. But here’s the thing people don’t always talk about: Dobuko is also an amazing cook. Yeah, that’s right—he whips up meals for his brothers regularly. It might seem small, but it shows another layer to his personality: he’s not just responsible; he genuinely cares. That nurturing side makes him more than just the “serious one”—he’s a caretaker in his own quiet way.

So overall, when you look at Dobuko Busujima as a whole, you’re looking at a character who embodies intelligence, stability, and deep loyalty. He’s the grounding force in a family full of wild energy, and in many ways, he serves as a role model—even if the others don’t always admit it.

Now, let’s dive a bit deeper into personality types, because Dobuko Busujima is a fascinating case study. Based on his behavior throughout Mr. Osomatsu, there’s a strong chance he fits the ISTJ personality type in the MBTI framework. ISTJs are known for being practical, organized, and big on tradition—all traits that describe Dobuko to a T. His strict adherence to rules, strong work ethic, and no-nonsense attitude line up perfectly with the ISTJ profile. He holds himself—and others—to high standards, which can make him seem critical at times, but it comes from a place of responsibility.

Also, notice how Dobuko isn’t one for long emotional speeches? He doesn’t wear his heart on his sleeve. Instead, he shows care through actions—like cooking dinner or quietly fixing problems before they escalate. That’s textbook ISTJ introverted feeling: expressing love and concern indirectly, through deeds rather than words.

And then there’s the Enneagram angle. When we look at Dobuko Busujima through that lens, Type 6—”The Loyalist”—really stands out. Why? Because Dobuko deeply values security, both emotionally and socially. He’s loyal to his family above all else, constantly seeking stability in a world that’s anything but stable. He often looks for reassurance, checks in on his brothers, and worries about potential risks—sometimes a little too much. That underlying anxiety? Yeah, that’s classic Type 6 energy. He anticipates problems before they happen, which can stress him out, but it also means he’s prepared.

But here’s the thing about Dobuko Busujima: even when he’s anxious or doubting himself, he doesn’t back down. When push comes to shove, he shows real courage. He’ll stand up for his principles and protect his loved ones without hesitation. That blend of caution and bravery? That’s the heart of a true Type 6.

So putting it all together—Dobuko Busujima is more than just the straight-laced older brother. He’s a complex character shaped by duty, loyalty, and quiet strength. Whether you see him as an ISTJ, a Type 6, or just a cool guy in glasses, one thing’s for sure: Dobuko Busujima plays a vital role in Mr. Osomatsu. And honestly? We wouldn’t want the show without him.
