Business Overview

About Rakuten’s Business
We are a core marketing organization that supports over 70 diverse services within the Rakuten Group, both in Japan and internationally.

Roles and Strengths of GMSD (Group Marketing Strategy Department)
Our mission goes beyond simply increasing cross-use metrics. We lead the following areas to maximize the brand value of the "Rakuten Group," elevate its impact, and strengthen the bond between users and Rakuten:

- Embodying Brand Identity: Reconstructing Rakuten’s powerful assets within a brand strategy context. We design unified brand communication and experiences across the entire group.

- Accelerating Cross-Use through User Experience: Leveraging data-driven analysis and collaborating with each business unit to visualize the "emotional value" of using Rakuten’s services, thereby driving cross-use through the power of our brand.

- Building a "Rakuten" Design Foundation: Our creative team establishes design systems and UI/UX standards, ensuring that users feel the "Rakuten identity" across every service, embedding our world-view into society.

- Group Marketing: Orchestrating all marketing channel strategies from a group-wide perspective to lead the design of optimal experiences at every user touchpoint.

We are looking for individuals to join us in this challenge—using the power of marketing to leave a mark on our massive ecosystem and ensuring "Rakuten" remains an indispensable presence for our users.

Department Overview

The Data & Insights Group utilizes data from across the Rakuten Group to rigorously measure the Return on Investment (ROI) of marketing initiatives and provide recommendations for budget optimization, driving profitability for the entire group.
