Foundational research into intelligence, decision realism, and long-horizon AI systems.
Himitsu Lab Limited is an Advanced AI research organization focused on how intelligent systems understand the world, reason under uncertainty, and act safely in real environments. Since 2019, our research has contributed to Native AI Intelligence and the long-term foundations of trustworthy machine intelligence.
Our work studies the scientific foundations of Native AI Intelligence - internal world understanding, uncertainty-aware reasoning, decision realism, and safe real-world action across digital and physical environments.
We pursue decision-complete intelligence, where systems know when to act, when not to act, and when to seek human input.
World Model+ is our architectural framework for Native AI Intelligence and decisions. It extends classical world models with uncertainty-aware reasoning, decision timing, safe plan-to-act execution, escalation pathways, and continuous learning.
Designed for Native AI Intelligence that must operate safely under real-world uncertainty, time pressure, and operational constraints. World Model+ supports autonomous AI reasoning systems and autonomous systems research where safe decisions, pauses, and escalation matter.
We situate our work within the broader global research effort, alongside peers across the AI research community advancing reasoning, world modelling, embodied intelligence, distributed systems, and long-horizon security. Our research contributes one of several serious paths toward more capable and responsible intelligent systems.
