Japanese expert data
Train your model on Japan's Juiciest Data
Expert judgment from licensed Japanese practitioners.
Tokyo / Independently held
AI has enough data. Now it needs better data.
The next generation of AI will not be built on more internet data. It will be built on data that captures real expertise, real judgment, and the way work is actually done.
Juice Data builds high-quality training data from Japan's professionals.

02 / Quality
More useful data in every hour.
We optimize every dataset for the things that matter to model training: how much happens, how much varies, and how reliably it is captured.
- Task density
- More tasks and meaningful actions captured per hour.
- Diversity
- Variation across environments, tools, workflows, and real-world conditions.
- Consistency
- A software-native pipeline for capture, structuring, validation, and delivery.
03 / Method
Nothing here came off the internet.
Practitioners write up their own experience as anonymized cases. Nothing proprietary leaves anyone's building, and there is no way to reproduce this with a translation tool or a synthetic pipeline.
04 / Independence
We are in Tokyo, and no model team owns a piece of us.
Nothing you send here ends up shaping a competitor's roadmap. If your side needs the data to stay in Japan, it stays in Japan.
