I’ve been looking at Anko Itosu’s 1908 letter again. It’s one of those documents people often cite. But if you look past the standard translations, I’m not sure the letter says what people think it says.

Itosu was in a difficult position. He wanted karate in the school system, which meant he had to make it palatable to the Okinawan education authorities and, by extension, the Japanese military interests of the time.

He had to make it structured, safe, and efficient for large groups. That’s where the physical education version of karate was born. But Itosu wasn’t just a bureaucrat; he was a man who understood the old ways of Shuri-te. Even as he was stripping the art down for children, he left clues in that letter that suggest he never intended for the school version to be mistaken for the whole version.

He talks about the “villain or ruffian” – the real-world threat, not a sporting opponent. He insists on striking practice and the repetition of kata until, as he puts it, you are naturally ready for a real encounter. He wasn’t talking about looking natural in a performance; he was talking about the physiological state of being prepared for violence.

Most importantly, he explicitly tells the reader to decide if their training is for health or for duty. That is a massive distinction. One is about building a better citizen; the other is about surviving a violent encounter.

The problem we face today isn’t that Itosu changed things. The problem is that we’ve lost the ability to distinguish between the two paths he laid out. Much of what is taught today – the rigid lines, the synchronized movements, the focus on external form – is perfectly suited for the physical education goal Itosu was pitching to the schools. It builds discipline, health, and structure. There is immense value in that. But the danger comes when we pretend that this specific type of training automatically prepares us for the villain he warned about.

We tend to look at this letter as a historical curiosity, but it’s actually a mirror. The uncomfortable truth is that many people spend decades training in a system designed for twelve-year-olds and then wonder why it feels hollow when they think about real-world violence.

If your training is dominated by synchronized lines, aesthetic precision, and a focus on the external look of a technique, you are participating in the health and physical education version of the art. There is nothing wrong with that, provided you are honest about it. The danger starts when we dress up that schoolyard version in the language of non-consensual violence.

Itosu was explicit. He didn’t say these two paths were the same thing; he said you have to choose one. He mentioned the makiwara, the villain, and the need to be naturally ready for a reason. Those aren’t concepts for a PE class; they are the remnants of a civilian protection system that he was trying to keep alive under the radar.

When we ignore that distinction, we aren’t preserving tradition – we are just repeating a misunderstanding that has been handed down for over a century. The letter isn’t just about what karate was; it’s a demand for us to decide what our karate is right now.

Are we building better citizens, or are we building the ability to survive? You can do both, but you can’t pretend they are the same thing.

Itosu knew exactly why he was adjusting the dial. He understood the context of the schoolyard versus the context of the street. I think we’ve taken the schoolyard version, polished it, and treated it as the ultimate expression of the art. We’ve kept the structure but forgotten the intent.

Karate doesn’t fail people – unclear goals do.

We should probably spend less time reciting Itosu’s letter and more time answering the question he posed in it: what is your training actually for?
