Our mission

The Target

We picked Billboard because a Japanese-language rap song has already been near the top of it.

For most independent rappers the US charts are still a long way off. Our part is the step before that: making your release understandable to people who don’t speak Japanese.

We can’t promise a chart position, and we won’t pretend to.

言葉の壁で止まっているリリースを、英語でも届く形にして出す。それが私たちの仕事です。目標はアメリカの Billboard チャート。そこに向けて、一枚ずつ英語で届けていきます。

FAQ

Common Questions

Why $399 to $499?

It’s six pieces of work for one release, written by someone who reads Japanese rap closely, done in two days. Priced separately, translation, subtitling and pitch writing would likely cost more and take longer.

Couldn’t I do this with AI for free?

You could get a literal translation. Rap lyrics lean on slang, dialect, double meanings and rhythm, and a literal translation usually flattens them. We use tools where they help, then a person rewrites every line, and you approve it before anything goes out.

How long does it take?

48 hours per release, counted from when we have your lyrics, video, bio facts and the deposit.

Who owns the rights?

You keep 100% of the rights to your music. We only do the language and packaging work and take no share of your masters, publishing or royalties.

Do you guarantee streams or chart positions?

No. Nobody can, and you should be careful with anyone who says they can.
