An innovative shower recycles five gallons of water for two weeks

in Innovation by

If in Europe severe winter weather is wreaking havoc, on other continents drought is a serious issue. Scarcity of water is not a new issue especially in Africa. Two Japanese engineers seem to have found a spectacular answer to save water! Using the device they developed, you would take 50 showers … with only 20 litres of water!

If you are moving or going on a camping trip, you can take it with you!

With the Hotaru shower Riki Kitawaga and Ryo Yamada had only one idea in mind: optimize as much as possible the water filtration potential for maximum recycling. And they succeeded!

The Hotaru shower invented by these two Japanese would be able, on each use, to recycle between 95 to 98 percent of the water contained in the tank. While on average, one shower requires 80 litres of water; with the Hotaru shower you will use 20 litres of water for 50 showers!

At first many persons rightly questioned, about the hygienic aspect of the device. But they have been reassured by the designers. Equipped with a pump and a filter, the system also possesses inbuilt detectors that measure the quality of the water and sends an alert in the event of a problem…

But this is not the only advantage of this invention. Compact and lightweight, it can be taken anywhere, provided it has access to a minimum of electricity. This is not a big issue, as the cigarette lighter of a car is enough… However, for hot water, it must still plug into an AC outlet.


In summary, the Hotaru shower would save substantial savings while preserving one of the most precious natural resources and reclaiming the pleasure of long showers. And if you are moving or going on a camping trip, you can take it with you!

Seduced by the Hotaru shower, Japanese billionaire Taizo Son decided to sponsor the project. As a result, the first Hotaru showers should be marketed this year around € 2,700.
