Job Purpose Summary

As the leader of Japan's Commercial Forecasting & Analytics department, this role is accountable for leading a team of forecasting, integrated demand planning and analytics professionals, shaping forecasting strategy, and providing executive leadership with robust forecasts, market insights and scenario-based recommendations that drive business decisions.

Working closely with Commercial, Finance, Medical, and Market Access, the role develops, challenges and refines commercial assumptions, translates market uncertainty into actionable business scenarios, and ensures alignment between commercial ambition, demand plans and operational feasibility.

Lead integrated forecasting and demand planning

Represent Japan in Global planning process and ensure forecast accountability

·  Own Japan's forecast submission process and ensure forecasts are submitted accurately and on time as part of the commercial planning cycle.

·  Act as the key representative for Japan in regional demand discussion, providing clear explanations of forecast assumptions, business context, market dynamics, risks, and opportunities.
