No need for plumbing or electricity. A futuristic toilet that allows for "flushing" anywhere.

This is a completely self-circulating flush toilet that cleans and circulates wastewater simply by supplying water during installation. Since it is a flush type and all processing occurs within the system, there is almost no need for vacuum trucks to empty it. Additionally, it can be reused without discharging water, making it eco-friendly, low-cost, and energy-efficient. ✨ Furthermore, it can be customized to meet customer needs! ☞ Low maintenance costs Due to the circulation system for sewage, the running costs are nearly zero! The power supply also utilizes solar power systems, resulting in zero power consumption! ☞ Environmentally friendly with advanced wastewater treatment capabilities By utilizing a unique patented technology for separation tanks, the water quality after purification is such that fish can live in it, eliminating odors and being considerate of the environment. ☞ Contributing to the community even in case of disasters Even in situations where flush toilets cannot be used due to disasters, water outages, or power outages, the solar power system allows for safe toilet use! It can also be transported by truck, making it ideal for evacuation centers. ☞ Can be installed anywhere Suitable for event venues, festivals, construction sites, glamping facilities, and campgrounds. It can also be installed in mountainous areas where there is no power, water, or ability to empty tanks.

Applications/Examples of results

【Introduction of Achievements】 Fujiyama Twin Terrace Parking Lot in Fuefuki City This is a tourist spot in Fuefuki City, Yamanashi Prefecture, where you can enjoy a spectacular view of Mount Fuji from the observation deck. Due to the lack of electricity and water, a temporary pit toilet was initially used on site, but for reasons related to odor and hygiene, we have installed Astia mobile temporary flush toilets.
