How You Can Help Us
Pirika is tackling the global litter problem, which poses a significant threat to our environment. We need your help to eliminate litter from the world.
We can help you energize your clean-up efforts using the power of SNS and provide you with litter research and other related consulting services. We have worked with Fukui Prefecture, Minato City (Tokyo), Meguro City (Tokyo), Kawasaki City (Kanagawa) and Maebashi City (Gunma Prefecture).
Eliminate litter from the world using the power of social media

Design litterless cities using artificial intelligence
Takanome is an AI-based program that maps and measures litter using visual recognition technology. We aim to contribute to designing litterless cities by evaluating anti-litter efforts with our cutting-edge research and providing other consulting services related to urban development.

Reducing Ocean Microplastic Pollution
We have started to develop a method to capture samples of microplastics as they flow toward the sea. Rivers, ports, sewage plants -- every point of outflow has its own unique conditions. We invented Albatross as a flexible research device that can be used under all of these unique conditions. Please visit here for detail.
