Japan Invents Mobile Toilets

Admin September 28, 2026

Japan has invented a variety of innovative mobile toilets, which are detailed below:

Portable Toilet minimLET

The portable toilet minimLET designed by Japan's Nendo company is highly distinctive. It simplifies the toilet into six components: a C-shaped toilet seat, aluminum tubes, nylon tent fabric, toilet paper, garbage bags, and coagulant. Setting it up is very convenient. Insert the aluminum tubes into the holes beneath the C-shaped seat to transform it into a small stool. Moreover, there are holes of different sizes beneath the seat. In special circumstances, mineral water bottles and stacked cans can also serve as toilet supports. Then, place a garbage bag at the bottom of the seat, and a simple toilet is ready. Additionally, the aluminum tubes, nylon fabric, and an umbrella can jointly support a small tent, ensuring privacy for users. The nylon fabric also has multiple uses; it can be directly worn as a cloak. The gray backpack that comes with the toilet can hold 16 liters of water. In emergencies, this water can be used for both storage and firefighting, making it highly versatile and practical.

"Folding" Toilet

Japan has also invented the "folding" toilet, whose biggest advantage is its portability. For women, queuing for toilets in public places is a common issue. The emergence of the "folding" toilet provides convenience for women, enabling them to resolve their toilet needs promptly when required and avoiding the hassle of long queues.

Otohime

Invented by Japan's TOTO company in 1988, Otohime is an electronic device primarily used in women's public toilets. When using the toilet in public places, people may feel embarrassed by the sounds. Otohime cleverly masks these sounds by emitting the sound of running water or musical clips, creating a relatively private and comfortable environment for users. This reflects Japan's meticulous consideration of user experience in toilet design.
