Cross&Crown Japan

What Cross&Crown Japan does

Cross&Crown Japan (Cross&Crown合同会社) is a Tokyo-based management and IT consulting firm founded in March 2008 by representative partner Masuko Takahito (増子 貴仁) and incorporated in September 2009. The firm focuses on Japanese small-to-medium enterprises and mid-tier companies underserved by large consultancies, offering business turnaround, operational improvement, financing support, and increasingly AI-driven consulting services. Headquartered in Minato-ku, Tokyo, with a secondary office in Osaka, Cross&Crown reports supporting more than 500 companies across industries since founding, with a stated 95%+ project success rate. The company has grown debt-free for 10 years and increased its capital to ¥11.27 million in August 2017 without external venture investment.

The firm's core offering is a three-service portfolio: Management Consulting (accompanied business improvement at ¥300,000+/month), AI Consulting (3-6 month AI adoption engagements at ¥98,000–¥220,000+ entry), and AI Company, a flagship product launched in 2024 that constructs an on-premise multi-agent AI organization for the client by integrating Anthropic's Claude, OpenAI's Codex, and Google's Gemini. The AI Company architecture runs locally via WSL on the client's own machine, embeds the company's documents and data into a knowledge base, and uses role-based agents (Management AI, Marketing AI, Analysis AI, Operations AI, HR AI) coordinated through a request-execution-mutual review-human approval workflow. Supporting technical assets include the open-source CCSI-LLM-Security framework (Apache 2.0), a 6-layer LLM defense architecture, and AI-independent automation tools designed to continue operating when AI services are unavailable.

Cross&Crown operates a primarily subscription-based revenue model with monthly fees starting at ¥98,000, plus initial setup fees ranging from ¥110,000 to ¥880,000+, and custom Enterprise contracts. Ancillary revenue streams include one-time system development work, low-cost website production under the Webma! brand, CMS Guardian security/backup (~¥10,000+/month), and cybersecurity services housed in the wholly-owned subsidiary Cross&Crown Security Intelligence LLC, which also runs the Michinori digital estate investigation and Sou-sou-roku online memorial services. Go-to-market is entirely web-driven: the company has historically operated without dedicated sales staff, acquiring clients through its website, free 60-minute consultations, a 48-page downloadable service PDF, case studies, SEO, and contributed articles in SME publications.
