Expanding to Japan
Claude's official developer account (@ClaudeDevs) has announced the return and expansion of the Claude Code Hackathon to the Japanese market. The registration portal is officially open and will accept submissions until 23:59 JST on October 26, 2026.
According to the organizers, the competition is not limited to software engineers, but is open to all builders living in Japan. The goal of the event is to encourage individuals and teams to leverage Claude Code to build real-world products and present them to the wider community.
Deepening Developer Engagement
Claude Code is Anthropic's AI-driven command-line interface (CLI) tool, engineered to assist developers in interacting directly with codebases and automating complex engineering workflows. Hosting the hackathon in Japan marks a deeper commitment to engaging developer communities across East Asia.
However, the announcement on X did not share specific details regarding the prize pool, format (online or in-person), or evaluation criteria for participating projects.
