“Off-the-grid housing module” that recycles all domestic wastewater will be exhibited at CEATEC 2022.


WOTA Corporation (CEO: Yaosuke Maeda, from now on referred to as “WOTA”) will exhibit an “off-the-grid housing module” equipped with WOTA’s “small-scale decentralized water circulation system” at CEATEC 2022 (from now on referred to as “CEATEC”) from Tuesday, October 18, 2022, to Friday, October 21, 2022.

CEATEC 2022 will be the first face-to-face exhibition in three years to realize “Society 5.0,” which balances economic development with solutions to social issues. It also envisions the future through “co-creation” by bringing people, technology, and information together from all industries and business sectors.

On Wednesday, October 19, 2022, from 12:20 p.m. -1:00 p.m., Maeda, our CEO, Mr. Kasai, Representative Director of Hokuryo Corporation, and Mr. Sakai, Representative Director/Founder & CEO of MUSIVI Corporation, will talk about “Social Change and the Future through Sustainable Distributed Infrastructure.” Maeda will speak on the theme of “Social Transformation and the Future through Sustainable Distributed Infrastructure.” We look forward to seeing you there.

About the “off-the-grid housing module”
The “WHOLE EARTH CUBE” developed by Hokuryo Corporation (CEO: Takeshi Kasai, hereafter “Hokuryo”) has a concept of “anyone living freely anywhere.” It is an “off-the-grid housing module” that allows people to live without being separated by various boundaries while staying connected to nature and the community to which they are attached. The “WHOLE EARTH CUBE” is equipped with MUSVI Corporation’s (CEO / Founder & CEO Yusuke Sakai, from now on “MUSVI”) telepresence system “Window” and WOTA’s “small-scale decentralized water reuse system.”

About the Conference
On Wednesday, October 19, from 12:20-13:00, a panel discussion will be held at the Talk Stage Trend/Future, featuring Hokuryo President Kasai, MUSVI President Sakai, and WOTA Representative Maeda.

Under the title of “Social Transformation and the Future with Sustainable Distributed Infrastructure,” we will discuss how a small-scale distributed infrastructure can solve existing infrastructure problems, such as maintenance costs, tremendous repair work, and inflexible urban planning. We will also discuss new lifestyles that embody Society 5.0 and are not bound by regions or infrastructure.

About the System to Recycle All Domestic Wastewater

The system for recycling all domestic wastewater is a system that collects all wastewater, recycles it through membrane treatment, biological treatment, disinfection, and other processes, and safely circulates it for reuse. Using our proprietary “water treatment autonomous control system,” the system flexibly controls water treatment in response to fluctuations in domestic wastewater, thereby achieving advanced management at the level of large-scale treatment plants and maintaining water safety at the WHO-standard bacteria and virus removal rate, while also being able to reclaim various types of domestic wastewater (*).

About WOTA
WOTA is a Japanese start-up company that aims to “understand the water crisis from a structural perspective and take on the challenge of solving it.” WOTA is developing “water treatment autonomous control technology” and “small-scale decentralized water reuse systems” to solve various water crises caused by uneven distribution, depletion, and pollution of water resources on the earth.

Our products include “WOTA BOX,” a portable water reclamation plant that can be used as a temporary shower facility in times of disaster, and “WOSH,” a water circulation hand washing station that does not require running water. While these products have been used nationwide in Japan for disaster and hygiene measures, we have also demonstrated our future vision of a “small-scale decentralized water reuse system.”

We will continue to promote research and development and product diffusion, aiming to make a “small-scale decentralized water recycling society” in which people can freely use water resources more sustainably.
