Tokyo Tech Talks #4: Closing the Loop
Join us on May 26, 2026 at Build+ in Ebisu for an evening of talks and conversation about systems that act, observe, and adapt — from agents to feedback to real-time control.
We’re excited to announce Tokyo Tech Talks #4.
Last time, we looked at how data becomes something people can see and feel. This time, we want to follow what happens next: when a system observes the world it just acted on, learns from the result, and tries again. The theme for this event is Closing the Loop.

The Theme: Closing the Loop
Most software runs open-loop. It takes an input, produces an output, and stops paying attention. The interesting work happens when a system keeps watching — when the output becomes the next input, and behavior starts to change with the world it’s operating in.
That shape shows up everywhere right now. Agents that read their own results before deciding the next step. Recommender systems that watch what people actually click. Robots and control systems that correct themselves in real time. Evals that route changes back into the model that produced them. Once the loop is closed, the system stops being a static pipeline and starts being something that has a relationship with its environment.
What We’ll Explore
This event brings together people building systems where the output matters less than the loop around it.
Agents That Observe and Re-plan
LLM agents are most interesting when they get to look at the world after acting on it. We’ll look at how people are structuring observation, memory, and re-planning so that an agent’s second move is better than its first.
Feedback as a First-Class Input
When telemetry, evaluation, and user response feed back into the system that produced them, the design problem changes. We’ll hear from builders treating feedback not as a metric but as a primary input to the loop.
Acting in Real Time
Some loops only matter when they close fast. We’ll look at systems that react inside the window where the world is still changing — control systems, live media, real-time interaction — and what it takes to keep them honest.
Who Should Attend
- Engineers and developers building agents, control systems, or anything that adapts at runtime
- ML and research engineers working on evals, RL, or feedback-driven training
- Product and design people thinking about how systems should respond to people, not just serve them
- Anyone curious about what changes when software starts paying attention to its own output
Join Us
If you’re interested in attending, register here.
Come spend an evening with people building systems that don’t just run — they notice, react, and try again. The talks will be short, the demos concrete, and the conversation open-ended.
