East Asia
Overview
Tokyo provides Corpshore's Japanese language capability, with access to native Japanese speakers suited to annotation, evaluation, and RLHF tasks requiring cultural nuance and high linguistic precision.
Japanese AI training data has historically been scarce relative to demand, making Tokyo a strategic addition for clients building multilingual models with Japanese coverage.
UTC+9 alignment is shared with Seoul, enabling joint East Asian programs on a unified schedule.

Public, approximate country-level context for the Tokyo network. Figures are rounded and indicative, not Corpshore metrics.
Why Corpshore staffs here
Japanese: consistently under-resourced in multilingual AI training datasets relative to economic weight.
High literacy and precision standards among contributors support complex annotation and RLHF evaluation.
Cultural nuance depth for tasks requiring contextual, polite-register, and keigo-aware judgments.
UTC+9 alignment with Seoul enables coordinated Japan-Korea programs on the same shift.
GDPR-aligned DPA plus APPI (Act on the Protection of Personal Information) compliance.
Talent pool
Japan's highly educated workforce brings strong precision and attention to detail to annotation and evaluation tasks. Contributors with technology and media backgrounds are well-suited to RLHF preference ranking, where culturally grounded judgment matters alongside linguistic accuracy.
Japanese requires specific register awareness — keigo (honorific language), polite forms, and contextual nuance — that only native annotators can reliably assess, making Tokyo irreplaceable for high-quality Japanese training data.
Specializations
Japanese text annotation with register and keigo awareness.
RLHF preference ranking for Japanese-language models.
Speech capture for Japanese TTS and ASR.
General annotation and labeling for Japan-market AI programs.
Egocentric video collection: first-person and POV footage for embodied AI and robotics training.
Field data collection: real-world environmental, sensor, and contextual data captured in-country.
Data residency and compliance
GDPR-aligned DPA, APPI
The Tokyo network operates under a GDPR-aligned data processing agreement and Japan's APPI (Act on the Protection of Personal Information), satisfying both international and local data-handling requirements. Access controls follow the Corpshore network standard.
Timezone coverage
UTC+9 (JST) is shared with Seoul and overlaps the late Beijing and Singapore windows, anchoring the East Asian portion of Corpshore's follow-the-sun coverage.
Why this location works for AI data
Japanese training data is consistently under-resourced relative to the language's economic footprint.
Register and keigo precision requirements make native annotators essential, not optional.
UTC+9 enables joint Tokyo-Seoul programs on a single East Asian shift.
APPI compliance adds a local data-protection layer alongside the GDPR-aligned DPA.
