We make brand leaders’ work easier.
No translation. No copywriting.
Welcome to the self‑driving era of content—AI proposes, local consumers perfect, and YOU approve.
Brand‑safe by design.

Welcome to Tetra Tokyo.
We’re an AI creative startup reshaping the advertising industry.
We aim for happiness.
We celebrate diversity.
We believe in the power of technology.
We break down language barriers.
We create a future where brands cross borders and coexist with the communities they serve.
Let us help your brand become globally loved —
just like these brands we've had the pleasure of working with.
Make the native make sense.
Know Before You Go.
In Japan, “I love you” was once translated as
“The moon is beautiful tonight.”
Between the words. Like haiku.
For brands, this is where things break.
Not because it’s lost in translation — but because the game changes.
What reads as clear elsewhere can feel blunt, loud, or empty here.

Where Culture Meets
Brand Strategy

On‑brand.
Your brand’s integrity—consistently.
A custom AI that rigorously enforces your brand guidelines works as part of your team, delivering a consistent brand voice across every customer touchpoint. It also engages in conversation.
Starting with Japanese.
As a sample of Brand AI, have a listen to the radio program we supported with our AI technology.
“AI Shoko” — a 20‑year‑old from 1945 — crosses time to talk about love with today’s university students.
