I suggest leaving "Work" untranslated (as "Work") in the Japanese UI for Rovo Chat, rather than translating it to "作業" (Sagyo) or similar terms.

Rationale:

1. Mismatched Nuance of "作業" (Sagyo):
   In Japanese, the term "作業" implies low-level, repetitive, or atomic operations (e.g., manual data entry or basic tasks). It fails to convey the core capability of this mode - formulating multi-step plans, making contextual decisions along the way, and driving complex, sequential outcomes.
2. Alignment with Industry Trends & User Mental Models:
   Across the AI landscape, similar capabilities retain their English nomenclature (e.g., Claude Cowork, ChatGPT Work, Copilot Cowork). Japanese users in the tech and enterprise sectors are already accustomed to "Work" in these agentic, collaborative contexts. Leaving it as "Work" maintains a modern, capable impression and aligns with standard industry terminology.
3. Consistency & Brand Identity:
   Keeping "Work" untranslated clearly distinguishes this autonomous, multi-step problem-solving capability from simple, transactional command execution.

Conclusion:
Please keep the English term "Work" in the Japanese locale.
