📍 Tokyo, Japan · 🤖 NLP Engineer · 🔧 AI Agents & Harness Engineering
I’m an NLP Engineer with a background in natural language processing, knowledge graphs, and LLM applications.
More recently, I’ve been exploring AI Agents and Harness Engineering, building tools, interfaces, and workflows that make agents easier to steer, inspect, and use in real-world tasks.
My current interests include agentic workflows, developer tooling, human-in-the-loop systems, and building practical agent applications.
- 🤖 AI Agents
- 🔧 Agent Harnesses & Developer Tooling
- 🔄 Human-in-the-loop Agent Workflows
- 🧩 Agent UX & Tool Interfaces
- 🧠 LLM & NLP Applications
- 📝 Japanese Language Processing
I'm especially interested in the layer around the model: how agents use tools, receive feedback, manage workflows, and interact with humans.

Building at the intersection of:
AI Agents × Harness Engineering × Developer Tools × NLP
I like turning emerging agent ideas into small, practical tools and learning what actually works by building them.
