The Conceptual Leap

This website is currently like a personal playground for a Japanese guy. He has no English-speaking friends and hardly any opportunity to use English in daily life. ChatGPT is pretty much his only companion who speaks English. Feeling isolated, he felt he should share his life with the English-speaking world.

Right now, he’s keeping work logs in English to practice — like this:

Jazz is the Kotodama of English

To understand English, you must feel its rhythm — and that rhythm lives in jazz. Discover why vocabulary alone can never reveal the emotions behind English, and how Offbeat Counting opens the door to both groove and language.

The Blind Spot in Japanese Perception

There’s a rhythm that Japanese people can’t pick up on. Even though you can discern the pitch when listening to it in isolation, once it’s placed in a certain position, there’s a blind spot in rhythm perception where the very existence of the sound becomes unrecognizable. This is an entirely separate issue from not being able to discern pitch, and it requires dedicated corrective training.

Be Myself

A poem about breaking the boundaries of identity — where self, others, and the world dissolve into a single rhythmic existence. It reveals that the world you perceive is a model inside your mind, and therefore, the world is also you.

The Essence of Jazz Is Rhythm Switching

Jazz isn’t defined by a specific rhythm - its essence is the act of switching rhythms. Rhythm varies, but jazz itself does not. Jazz matters because it reveals the importance of rhythmic transformation; without rhythm switching, it is no longer jazz.

    • It’s not that rhythm is important to jazz

Triple Offbeat-Leading Rhythm

The SNL shopping-skit theme uses a fully offbeat-leading, tail-to-tail rhythmic structure that feels ordinary to Americans but is nearly unrecognizable to Japanese listeners, revealing how deeply linguistic habits shape unconscious rhythmic perception.
