Latest Sakana AI News
Nov 17, 2025
Founded about two years ago, Sakana AI is working on AI technologies aimed at supporting Japan's economic and demographic needs. 🧠 Food for thought Implications, context, and why it matters. Funding momentum without verifiable product traction Sakana AI raised $135 million, while third-party listings show $0 reported revenue and no prior funding . That gap invites questions about traction in Japan's AI market. The company cites partnerships in finance, defense, and manufacturing. Public sources list few verified deployments or revenue details, while Fujitsu's Takane LLM (a Japan-focused enterprise large language model) names Mizuho Financial Group and Mitsubishi Electric as customers Open-source releases and ideas like the Continuous Thought Machine (an AI architecture concept introduced by Sakana AI) lack independent validation or adoption metrics. The gap makes it hard to judge technical leadership beyond press posts. Opportunity for third-party Japanese AI tooling providers Local adoption creates space for specialized tools in Japanese-language evaluation and domain datasets. EDINET-Bench (an open-source financial benchmark built from Japan's Electronic Disclosure for Investors' Network, or EDINET) finds that leading LLMs barely beat baselines on fraud detection and earnings forecasting IT service firms plus tooling startups can offer fine-tuning and knowledge graphs (structured representations of entities and relationships). They can also build retrieval-augmented generation, or RAG, tailored to Japan's rules and industries. Fujitsu's Takane LLM integrates knowledge graphs with RAG, targeting sectors like government and healthcare Japanese financial AI remains underserved versus English-language models . That gap opens room for infrastructure built for Japan's language and rules as firms seek options to handle sensitive data without general-purpose cloud LLMs
