SATO is broadening its product portfolio to address the evolving demands of our growing customer base, thereby establishing a sustainable social business. As we expand our sales network into more remote regions, we are working to meet the broader needs of people and communities. By diversifying our offerings, we believe that we empower people around the world to lead better lives and look forward to a brighter future.

SATO's product range, manufactured within Asia and Africa, has consistently reached the milestone of distributing 1 million units annually over the past five years. As of March 31, 2024, we have shipped approximately 8.6 million units across 45 countries, improving sanitation and hygiene for an estimated 68 million people. In FYE2024, we launched the SATO business in the Philippines and Indonesia, with local production established through our newly appointed manufacturing partners. Furthering our market expansion, we have also entered Madagascar in collaboration with USAID's Partnership for Better Living. This approach underscores not only our commitment to improving global sanitation and hygiene but also supporting local economies.

SATO toilet solutions embody a range of innovative, affordable, and easy-to-install toilet systems, specifically designed for rural and peri-urban areas lacking access to basic sanitation facilities. Our water-efficient designs ensure efficient flushing with less than one liter of water. The waste is effectively managed via a counterweight trapdoor mechanism that opens during flushing to remove waste, then closes to mitigate odors and reduce disease-carrying insects, such as flies. Made from durable yet lightweight plastic material, SATO products are designed for effortless transportation and installation, a vital consideration for remote and rural communities where transport options are limited. In our ongoing commitment to sustainability and innovation, we are exploring the use of recycled plastics and alternatives to fossil fuel-derived plastics to further reduce our environmental footprint.

・SATO Pan

The original SATO model, the SATO Pan was developed to address the sanitation needs of communities in Bangladesh. This pioneering model emerged as an affordable solution for constructing new latrines and upgrading existing ones.Starting the production and sales in 2013, Bangladesh is the inaugural market for the SATO brand.

Conceived during the COVID-19 pandemic, SATO Tap is a compact and portable handwashing solution designed to facilitate better hygiene practices in homes and communities. Recognizing the diverse needs of regions worldwide, especially those with limited access to water or handwashing facilities, our product development team adopted a user-centric approach. This approach prioritized simple materials and production methods, ensuring the SATO Tap was not only easy to use but also cost-effective to produce. As a result, the SATO Tap was strategically priced to be affordable, making it a feasible option for widespread distribution and adoption across various customers without access to running water.

SATO Tap consists of a plastic base with a nozzle that can be fitted with widely available plastic bottle shapes and sizes. It uses gravity, delivering a minimal and controlled flow of water—just 100 ml—that is sufficient for effective handwashing, achieving an impressive 90% reduction in water usage compared to conventional taps. In the Philippines, a survey conducted by the German Agency for International Cooperation (GIZ) affirmed the SATO Tap's exceptional water-saving capabilities, particularly in school settings where such efficiency is crucial. The manufacturing simplicity of the SATO Tap's plastic components not only keeps production and retail costs low but also promotes the reuse of plastic bottles, thereby contributing to the reduction of single-use plastic waste.
