Case Study: Rakuten accelerates software development with Anthropic’s Claude Code

Rakuten accelerates development with Claude Code

Rakuten, a major Japanese technology company, sought to accelerate software development and innovation across its diverse businesses. The challenge was to find an AI coding tool that could handle complex, multi-language codebases autonomously at an enterprise scale while maintaining high quality and security standards.

Anthropic's Claude Code provided the solution, enabling sustained autonomous coding and parallel development. The implementation resulted in a 79% reduction in time to market for new features, dropping from 24 days to just 5 days, and achieved 99.9% accuracy on complex code modifications, dramatically accelerating Rakuten's ability to deliver value to customers.
