Portable Toilet Management System hint

Portable toilets have evolved

Recently, there are more outdoor events such as music festivals and fireworks shows, where regular people use portable toilets. More portable toilets are also western style, and more people are demanding clean and comfortable toilet spaces. “hint” is a system that collects data on the usage of the portable toilets and manages them on a website. We aim to provide toilet environments that are comfortable and safe for both the managers and users of portable toilets. Using IoT technology, hint propels us toward a new era of portable toilets.

We are currently recruiting monitor stores.

Winner of Good Design Award Best 100


Our portable toilet management system: hint was awarded the 2019 Good Design Awards Best 100. It was also selected as a “judge’s favorite”.
The “Good Design Award (G Mark)” is the only system in Japan for evaluating and promoting design, conducted by the Japan Institute of Design Promotion. Many companies and other organizations both from Japan and abroad participate in these awards to make our lives, industries, and society as a whole more prosperous, by selecting and awarding “good designs” from among various developments in the year.
Judges highly praised our system when selecting the Best 100.

“By implementing IoT in portable toilets, the company has offered a stress-free system that not only tells users which units are unoccupied, but also gives the remote maintenance company updated information on the levels of water and septic tank. Designed specifically for porta potties, it offers convenience and an indispensable service in an area where the significance is often overlooked. It is developed with the use at large-scale events such as fireworks and music festivals in mind, but will sure become extremely useful at construction sites and in the event of emergency such as natural disasters. All the judges gave high appraisal for offering a lightly regarded but important service.”
