Expo 2025 Osaka, Kansai, Japan
RIKEN will have an exhibition and provide exhibit support at EXPO 2025 in Osaka from April 13 to October 13, 2025. The theme of Expo 2025 is “Designing Future Society for Our Lives.” Make sure to check out RIKEN's cutting edge research at the Expo!

Cooperation with Signature pavilion: Future of Life

RIKEN projects and Centers are collaborating with the Signature Pavilion "Future of Life," which was created by leading robotics engineering expert, Professor Hiroshi Ishiguro.
- Conversational robots that provide appropriate information based on the observed context.
Two robots from the Guardian Robot Project will be showcased conversing at the Expo and pavilion. The robots are able to engage in conversations that are appropriate to the situation while being aware of what's going on around them. Enjoy the feeling of co-existence with the robots at the pavilion.

- Whole human brain simulation and brain analysis inducing artificial general intelligence
A future where a digital copy of the human brain can be created The RIKEN Center for Computational Science (R-CCS) will collaborate in this research exhibit which uses the supercomputer Fugaku. With collaboration from Dr. Tadashi Yamazaki at the University of Electro-Communications, the project was supervised by RIKEN's High Performance Artificial Intelligence Systems Research Team Leader Dr. Mohamed Wahib and Senior Scientist Dr. Jun Igarashi.
They will showcase two technologies relating to human whole brain analysis including how the brain understands and judges information using human whole brain simulations. The technology uses generative AI and image analysis using the power of Fugaku to reproduce the some 86 billion neurons that make up the human brain.

Kokoro + Robot Lab: The day when people say "thank you" to robots
Exhibition of dialogue with autonomous learning robots that care for people and provide them with subtle support.

The Guardian Robot Project will have an exhibition at the Future Life Experience in Expo 2025's Future Society Showcase.
Visitors can have a conversation with a robot that can carry out autonomous communication with people by surmising a person's latent intent using memories obtained through the robot's own experiences.

Demonstration of high-precision data analysis with remote-sensing technology and real-time broadcasting (collaboration)


The R-CCS Data Assimilation Research Team is taking part in the Expo 2025‘s Action Plan with a demonstration of a high-precision numerical weather prediction system that uses advanced remote-sensing technology and real-time data transfer, operated using Fugaku supercomputer.
The system is the world‘s first at using dual multi-parameter phased array weather radar (MP-PAWR), an advanced radar which can observe the three-dimensional structure of rainfall. It is capable of high-precision rainfall prediction every 30 seconds up to 30 minutes in the future for rapidly evolving heavy rainfall systems at 500 meter resolution. Rain forecasts will be made public for about a month during the demonstration period on RIKEN's weather forecast research website and the app "3D raincloud watch."

(Collaboration with) entangle moment [quantum / earth / universe] × art

To commemorate the declaration of the year 2025 as the "International Year of Quantum Science and Technology," we will showcase an exhibit that "entangles" science, technology, and art under the three themes of the micro world of quantum; the ocean and earth that nurtures our lives; and the vastness of space.
RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) will showcase the "Black Hole Recorder." The Black Hole Recorder is a prototype that imagines a possibility where research on how information is stored within black holes could lead to future large-capacity information storage. It collects sound through a horn that simulates the curvature of spacetime around a black hole, with the capability to record and playback on an artificial black hole, designed through the concept of fictional black hole engineering.
The RIKEN Center for Quantum Computing (RQC) will collaborate with the exhibit by holding a quantum computer virtual reality experience.
