Japan's Funny Portable Toilets

Admin September 22, 2026

Japan has designed unique and funny portable toilets, mainly including the minimLET portable toilet, the 'World's Smallest Toilet', and Oki Sato's 'Portable Toilet'.

minimLET Portable Toilet: Developed by a Japanese company, it boasts extremely high portability and can be carried around easily. It consists of six components: a C-shaped seat ring, four lightweight aluminum rods, a garbage bag, a large piece of lightweight canvas, a coagulant, and a carrying bag. When in use, insert the four aluminum rods under the C-shaped seat pad. If aluminum rods are not available, plastic mineral water bottles can be used as a substitute. Then, put on the garbage bag to assemble a simple toilet. To avoid embarrassment for users, the designer has also considered privacy issues. Aluminum rods can be inserted through the small holes on the C-shaped seat pad to fix an opened umbrella, and then a tent made of nylon fabric can be put on. This tent can also be worn as a cloak in daily life. The gray carrying bag is made of waterproof material and can be used as a water bag in addition to holding components, holding up to 16 liters of water.

'World's Smallest Toilet': Known as the 'Pocket Toilet', its compactness is astonishing, being as small as the palm of a hand. When opened, it may seem like just a garbage bag, but it contains a lot inside, including a bag that can hold 1000ml, a coagulant, a deodorant, an odor-proof bag, and hand sanitizer. When in use, first find a toilet stand and put the bag on it. If there is no stand, the bag can be spread out and used as a squat toilet. Then, throw the deodorant and other materials into the bag. Finally, fold up the bag and put it into the odor-proof bag. After that, wash your hands. The whole process is both interesting and practical.

Oki Sato's 'Portable Toilet': It also has the characteristic of portability and can be put into a handbag. It consists of four aluminum rods, a C-shaped seat pad, a tent, tissue paper, a garbage bag, and a coagulant. The usage method is similar to that of the minimLET. Insert the four aluminum rods under the C-shaped seat pad. Four mineral water bottles filled with water or sand can also be used as a substitute. Then, put on the garbage bag to use it. To solve privacy issues, aluminum rods can also be inserted through the small holes on the C-shaped seat pad to fix an opened umbrella, and then the tent can be put on.
