Sakamoto Days Explained: The Secret Power Struggle Between JCC and JAA
If you’re deep into Sakamoto Days, either bingeing the manga or catching the latest anime, you know the world looks deceptively ordinary—but scratch the surface, and it’s pure chaos.
Behind the calm streets of Japan lie two massive organizations that dictate who lives, dies, or thrives in the underworld: the JCC (Japan Clear Creation) and the JAA (Japanese Association of Assassins).
On paper, they might sound like bureaucratic acronyms, but in practice, they’re a deadly ecosystem of training, control, and ruthless ambition.
As a long-time anime fan, I can tell you—the distinction between the two isn’t just academic. Understanding them changes how you see every fight, every mission, and every character’s choices.
So let’s break it down, fan-style, and uncover the hidden hierarchy of Sakamoto Days.

1. What is the JAA? The Corporate Overlords
The Japanese Association of Assassins (JAA) isn’t just an organization; it’s the shadow government of Japan’s assassination industry. Imagine a mega-corporation—but instead of office cubicles and spreadsheets, it’s filled with lethal killers and contract enforcement.
Key Roles of the JAA:
- Regulation: They control who’s allowed to be a professional hitman. A JAA license is basically your “corporate ID,” but getting it is infinitely harder than any Japanese driver’s license.
- Contract Handling: From life-or-death missions to “cleaning” up after them, the JAA keeps the underworld running smoothly.
- Monopoly: Almost every professional assassin in Japan falls under their umbrella. Refuse their cut—usually 30%—and you might be looking at a one-way ticket to your own grave.
- Public Perception: While feared in the underground, the JAA cleverly masquerades as security firms or corporate consultants.
The Order: Legends Within the JAA
Inside this already terrifying system exists The Order, a group of assassins so powerful they’re almost mythical. They take on only the highest-stakes threats—think of them as the “boss level” in the game of assassination. Rarely seen, almost never survived an encounter with them, they are the living embodiment of why the JAA rules the underworld.
2. What is the JCC? The Deadly Academy
If the JAA is the corporate overlord, the JCC is the elite academy that forges the next generation of assassins. It’s like Hogwarts for killers—but without the charming ghosts and cozy meals.
Inside the JCC:
- Purpose: Train, test, and weed out assassins. Only the strongest survive.
- History & Size: Operating for roughly 50 years, the academy hosts around 1,000 students in a four-year program.
- Graduation Rate: A brutal 10%. The rest either quit or die. No sugarcoating.
- Location: A remote, heavily guarded island keeps “extracurricular activities” safely away from civilian eyes.
Notorious Exams:
The entrance and transfer tests are legendary for sheer lethality. In one unforgettable instance, 360 applicants fought aboard a plane, and only seven survived, including Sakamoto and Shin. That’s not just schooling—that’s survival-of-the-fittest training.
3. JCC vs. JAA: Side-by-Side Comparison
It helps to see the two organizations next to each other. Here’s a quick guide:
| Feature | JCC (Japan Clear Creation) | JAA (Japanese Association of Assassins) |
|---|---|---|
| Nature | Training Academy | Governing Body / Corporate Entity |
| Goal | Forge elite assassins | Regulate and monetize the industry |
| Status | Prestigious School | National Monopoly |
| Key Members | Students, Instructors (e.g., Satoda) | Licensed Pros, The Order |
| Admission | Deadly entrance exams | License via exam or JCC alumni |
| Outcome | Skills, prestige | Authority, power, influence |
4. Do You Need JCC to Join the JAA?
A common fan question: is graduating from JCC mandatory to earn a JAA license? The answer is no—but it helps immensely.
- Alumni Advantage: Graduates like Sakamoto, Nagumo, and Rion Akao automatically get prestige and access to high-value contracts.
- Outsider Paths: Characters like Shin Asakura or Osaragi bypassed JCC entirely but still achieved elite status via external exams or exceptional skill.
Think of the JCC as the Ivy League of assassination—it’s not strictly necessary, but it certainly opens doors.
5. Corruption, Secrets, and the Dark Side
Both the JCC and JAA are far from heroic.
- JAA: Their corruption is systemic. From milking profits to manipulating assassins and contracts, they maintain control through fear and greed. This corruption drives antagonists like Slur to aim for their total destruction.
- JCC: While presented as a school, it’s complicit. By filtering the “weak” and promoting the ruthless, it ensures the JAA gets only the most lethal candidates.
6. Must-Watch Arcs for Fans
If you want to truly understand the power dynamics:
- JCC Transfer Exams Arc: Witness the lethal training process firsthand.
- JCC Infiltration Arc: Sakamoto and Shin go undercover, revealing the school’s inner workings and secrets of Slur.
- JAA Jail Arc: Explore the high-security prison that keeps rogue assassins—or failed ones—from wreaking havoc.
7. Final Thoughts: Why This Lore Matters
The brilliance of Sakamoto Days is how it layers seemingly ordinary life with an unseen, high-stakes hierarchy. The JCC teaches you how to kill, the JAA decides who gets killed. Together, they form a deadly ecosystem where every choice is life-or-death—and every character carries the weight of their training and affiliations.
As someone who’s followed the series obsessively, I can honestly say the tension between JCC alumni and JAA veterans adds depth beyond the action. Every fight isn’t just a brawl—it’s a clash of philosophy, skill, and survival instinct.
For anyone diving into the series, understanding these two organizations isn’t optional—it’s essential. Once you see how Sakamoto navigates both worlds, every subtle move, every calculated decision, and every quiet smile carries way more weight.
