Question 1

Does Corpshore provide AI training data in Japanese?

Accepted Answer

Yes. Corpshore delivers annotation, speech, and RLHF data in Japanese with native, in-region annotators across 3 dialects: Standard (Tokyo), Kansai, Kyushu. The data is dialect-deep and built by speakers who live in the language, not an English-first overlay.

Question 2

Which Japanese dialects do you cover?

Accepted Answer

Corpshore covers Standard (Tokyo), Kansai, Kyushu, with native speakers based in-region, primarily from the Manila hub. Dialect coverage is defined per project so the data matches the specific Japanese-speaking markets you serve.

Question 3

How many Japanese annotators does Corpshore have?

Accepted Answer

300+ native Japanese annotators. Annotation, RLHF, and evaluation in native Japanese. As a Japonic language, Japanese is handled by people fluent in its structure and everyday usage rather than second-language reviewers.

Question 4

Where are your Japanese annotators based?

Accepted Answer

Japanese annotators are based in-region across Japan, working primarily from the Manila hub. Because they live in the communities whose language they work in, the data reflects real usage, current vocabulary, and natural code-switching.

Question 5

What types of Japanese data can Corpshore deliver?

Accepted Answer

Corpshore produces Japanese annotation, including text labeling, classification, and NER, speech and audio datasets for TTS and ASR, and RLHF and evaluation data. Each type is delivered by native speakers and passes the three-tier QA cascade before handoff.

Question 6

How does Corpshore ensure quality for Japanese data?

Accepted Answer

Every unit of Japanese work passes the three-tier QA cascade: annotator plus peer review, an expert QA-lead audit, and programmatic consensus and gold-set checks, producing 97%+ accuracy. Native reviewers judge the language, so dialect and cultural nuance are checked rather than averaged away.

Question 7

Can Corpshore scale Japanese data collection?

Accepted Answer

Yes. With 300+ native Japanese annotators and dedicated pods rather than per-task marketplace bidding, Corpshore can hold a steady cadence and a consistent taxonomy as volume grows. Japanese is one of 35+ languages Corpshore covers with native, in-region talent.

Question 8

How do I start a Japanese data project?

Accepted Answer

Share your modality, volume, target Japanese dialects, and turnaround, and Corpshore returns an indicative team size, timeline, and cost band, then stands up a dedicated pod. You can start a pilot to validate quality on a real sample before committing to full volume.
