How Rakuten Built a Tech Empire by Breaking the Rules

Key Concepts

• Virtualization/Cloud-Native Mobile Network: A telecommunications architecture that replaces hardware-based infrastructure with software-defined, cloud-based systems.
• B2B2C (Business-to-Business-to-Consumer) Marketplace: A model where the platform empowers small merchants to sell directly to consumers.
• Englishnization: The strategic mandate to make English the official corporate language to facilitate global competitiveness and talent acquisition.
• Ecosystem Strategy: Integrating diverse services (e-commerce, finance, travel, mobile) through a unified loyalty point system.
• Entrepreneurial Power: The focus on fostering innovation and risk-taking to revitalize the Japanese economy.

1. The Evolution of Rakuten: From E-commerce to Telecom

Hiroshi Mikatani, founder of Rakuten, has built a multi-billion dollar conglomerate by consistently betting against conventional wisdom.

• E-commerce Origins: In the late 1990s, when internet shopping was widely considered a failing model, Mikatani launched Rakuten Ichiba. He focused on small merchants, often personally educating them on using PCs and digital cameras to digitize their businesses.
• Telecom Disruption: In 2019, Rakuten entered the mobile market by deploying the world’s first fully virtualized, cloud-native mobile network. Despite initial performance skepticism and years of financial losses, the network has matured. By December 2025, the unit reached 10 million subscribers and achieved its first full-year EBITDA profit, validating Mikatani’s "scientific proof" approach over market consensus.

2. Strategic Frameworks and Methodologies

• The "Englishnization" Mandate: To compete globally, Mikatani mandated that all employees switch to English. The rationale was twofold:
  1. Global Benchmarking: To compete with international firms rather than just domestic ones.
  2. Talent Acquisition: To hire from a global pool of engineers, as the domestic Japanese supply was insufficient.
  • Implementation: The process was gradual, involving intensive language training and deadline adjustments, eventually resulting in near-universal compliance.
• Leadership Philosophy: Mikatani defines the leader’s role as "sticking the flag"—setting a clear social and business mission. He prioritizes long-term investment over short-term profit maximization, arguing that immediate profit-taking would stifle the company's future growth.

3. Artificial Intelligence and Operational Efficiency

Mikatani views AI as a tool for massive operational optimization rather than a total replacement for human intellect.

• Efficiency Gains: Rakuten achieved a 10% improvement in operational efficiency through AI in the previous year.
• Financial Impact: Mikatani projects that a 20% improvement in operational efficiency could lead to a 50–60% increase in profit, highlighting the significant bottom-line impact of AI integration.

4. Global Branding through Sports

Rakuten utilizes high-profile sports sponsorships (Tohoku Rakuten Golden Eagles, Vissel Kobe, FC Barcelona, and the Golden State Warriors) as a strategic marketing tool.

• Rationale: Mikatani describes sports as "a drama without a scenario" that fosters community and emotion.
• Application: These partnerships provide global brand recognition, particularly in tech hubs like Silicon Valley, where the Rakuten brand is highly visible at venues like the Chase Center.

5. Key Arguments and Perspectives

• On Risk-Taking: Mikatani rejects the label of "troublemaker," instead framing his actions as a refusal to be constrained by conventional wisdom. He emphasizes that he does not act impulsively; he conducts rigorous research and lab testing before committing to major pivots like the mobile network.
• On the Japanese Economy: Mikatani expresses concern over Japan’s stagnant GDP growth over the last two decades. He believes that by proving a Japanese company can become a globally respected, entrepreneurial leader, he can help shift the direction of the Japanese private sector.

6. Notable Quotes

• "Everybody thought internet is going to be popular, but nobody will make any money from it. But I thought it's just a matter of time." — Hiroshi Mikatani on his early e-commerce vision.
• "We have to benchmark our global competitors, not our domestic competitors." — On the necessity of the English language mandate.
• "Making money is a means to do it [the social mission]. It's not the ultimate objective for me." — On his leadership philosophy.

Synthesis and Conclusion

Hiroshi Mikatani’s leadership at Rakuten is defined by a contrarian approach to business, characterized by long-term vision and a willingness to endure short-term criticism for long-term structural gains. By successfully transitioning from a niche e-commerce platform to a global, cloud-native telecom and tech ecosystem, Mikatani has demonstrated that traditional corporate structures can be successfully disrupted. His current focus on AI-driven efficiency and his mission to restore Japan’s entrepreneurial standing suggest that Rakuten will continue to prioritize aggressive, technology-led growth over conservative, short-term financial stability.
