Climate Technology Product Manufacturing in Japan

Jeplan, Inc

This company was founded on a simple idea: “We want to recycle the huge amount of clothing that is being thrown away every day.” By recycling unneeded items as components for making new things, we can use those materials over and over again. This is true not only for clothing, but also for other items that are no longer useful. Recycling reduces our reliance on petroleum and other mining resources, reduces the energy required for manufacturing processes, and lowers our emissions of carbon dioxide and other greenhouse gasses. Recycling is a key part of realizing a sustainable society, a vital issue for the entire world. We aim at an exciting world—one in which society as a whole works together to put everything back into circulation.

Ooyoo Ltd

OOYOO's cutting edge materials technology enhances air and gas purification for a cleaner and more mobile world. Purified gases, such as oxygen, carbon dioxide or natural gas play a crucial role in every part of our daily lives. Purifying gases comes at a cost, to industry, and failing to capture and purify some gases such as carbon dioxide, comes at a cost to our planet. Conventional sense is that the successful players in the chemical, health and energy sectors can profit by consolidating costs and developing large plants. OOYOO thinks differently, striving to deliver low-cost, small-footprint, air and gas cleaning technologies.

Spacecool Inc

SPACECOOL INC, a climate-tech startup, develops and sells the radiative cooling material SPACECOOL. SPACECOOL's unique optical technology can reflect the heat from sunlight to suppress heat absorption during the daytime, while also emitting heat into outside space by radiative cooling, creating temperatures cooler than the ambient air with zero energy. We are aiming to contribute to improving the heat issues for “people, things, society” worldwide, for example, resolving the thermal issues in outdoor electronic equipment, and reducing energy used for cooling, also preventing heat stroke by the extreme wethers.

Carbon Fly, Inc

About carbon nanotubes (CNTs) Today many industries are looking at CNTs as new structural or functional materials. CNTs have 100 times stronger mechanical strength than steel, yet are lightweight and flexible. CNTs are used as structural materials in space development and aeronautics, as well as construction and civil engineering. CNTs are also used as functional and composite material in the semiconductor and energy sectors (LiBs etc.) taking advantage of electrical conductivity resistance, which is around times higher than that of copper. CNTs also have extremely high thermal conductivity and heat resistance. Our uniqueness CarbonFly has developed a unique technology to grow CNTs with uniform control of diameter and length on a commercial scale. This has enabled the mass production of CNTs with higher quality, compared with conventional production processes. With this technology, Carbonfly offers 100% CNTs in a variety of forms (powders, films and cables) so that our clients can process this material easily. At the same time, our equipment is compact enough to install even in standard offices. Carbon recycle technology As a tech-driven company on this planet, environmental impact is a key driver of our R&D roadmap. We are developing CNTs production process using carbon dioxide (CO2) as a raw material with commercial viability. We believe our CNTs make a significant contribution to the carbon-neutrality of the world.

Atierra

To restore climate balance, we must remove 10 billion tons of CO₂ annually by 2050. But beyond the data, this is really about reimagining how we live, create, and connect with the planet. At Atierra, we harness the natural power of microalgae and enhance their potential with synthetic biology to not only remove CO₂, but also produce oils for applications in Sustainable Aviation Fuel (SAF) production. By unlocking these co-benefits, we aim to turn CO₂ into regenerative materials that help people and the planet thrive!

Gomi Snap

Gomi Snap is an AI-powered waste sorting application that provides real-time disposal guidance and behavior-level data. We built and deployed an MVP to address a simple gap: waste systems lack feedback at the moment people throw things away. Gomi Snap closes that gap by helping users sort correctly while generating insights organizations can actually use. The platform is designed to support universities and cities seeking practical, data-driven ways to reduce contamination and improve waste outcomes.
