ABOUT

Flagship is a Shopify Plus dedicated e-commerce agency based in Tokyo, Japan.

At Flagship Inc., we are a dedicated system integrator specializing exclusively in Shopify Plus, focusing all our resources on supporting enterprise-level e-commerce. We were the first company in Japan to be recognized as a Shopify Plus Partner, and in 2024, we were honored with the “Enterprise Partner of the Year” award from Shopify Japan. In 2025, we were also selected as a Shopify Premier Partner under the new global partner program. With one of the leading track records for Shopify Plus implementations in Japan, our highly specialized team provides end-to-end support for building, migrating, and operating enterprise e-commerce stores.

Why Flagship?

Filling the Gaps in Shopify with Our Own Apps

Our journey began by supporting Shopify HQ with early localization efforts, and since then, we have developed and delivered a wide range of original apps tailored to the unique needs of the Japanese market. Starting with solutions that address gaps in Shopify usage within Japan, we now provide apps—such as those for employee purchases—that go beyond local requirements to fill global white space in the Shopify ecosystem.

Marketplace Development with Mirakl

Since 2025, we have been actively promoting marketplace development using the powerful combination of Shopify Plus and Mirakl. By leveraging Shopify’s rich frontend capabilities alongside Mirakl’s robust product aggregation and seller management features, we enable brands and manufacturers to launch D2C-style marketplaces in a short timeframe. As one of the few Shopify implementation partners in Japan with deep expertise in Mirakl, we provide end-to-end support—from requirements definition and system development to ongoing operations and growth strategy.

We also support Mirakl integrations where the e-commerce frontend is not built on Shopify.

Global, Multilingual Team

Our team is made up of members from over 10 countries, with English as our common language. While language is important, what truly matters is the global sensibility we share as citizens of the world. Architects, project managers, engineers, and UX designers work in close collaboration—not only within the team, but also with the headquarters of global companies—to support domestic e-commerce operations. We have also successfully helped many Japanese enterprises expand their cross-border e-commerce business, leveraging our deep understanding of both local and global contexts.

Pioneering AI Integration in the Complex World of E-Commerce

From the very day ChatGPT emerged, we have been exploring how to effectively implement AI in the highly multifaceted and fast-paced world of e-commerce operations. AI technologies continue to evolve beyond our expectations, and both within and outside our organization, practical and battle-tested AI tools are rapidly becoming a reality. At Flagship, we are accelerating the planning, development, and deployment of AI agents designed to support e-commerce teams on the ground. From customer support and product listing to marketing automation and reporting, AI is already becoming a “second right hand” for those handling day-to-day EC operations. We are especially focused on developing Slack-integrated chatbots and are currently seeking pilot partners for trial implementation.

Security Focused

We are ISO27001 (ISMS) certified, ensuring the highest standards of information security management for our clients' peace of mind.
