WHAT is the Bubble90

A water-saving nozzle that conserves up to 95% water, significantly improves detergency, and requires no electricity to function.

With the power of the Bubble90, even hard to clean substances like wine, chocolate, coffee, grease, and even blood take much less time to wash off. This increased washing efficiency is what adds the last 5% to the average 90% water-saving capacity of the Bubble90.

Normally, nozzles with a high water-saving capacity lower the detergency power of the water stream too much, and that makes them unfit for industrial use. On the other hand, nozzles with low water-saving capacity provide only marginal benefits. In an unprecedented feat of engineering, the Bubble90 combines the best of both. It is, by far,

the world’s best amalgam of extreme water-saving and 
high cleaning power.

Thanks to this breakthrough, we have been able to tailor the benefits of water conservation to the fast-paced needs of the industry. Our clients include factories and local businesses, major hotels and supermarkets, chain stores and restaurants, hospitals and welfare institutions, as well as many others. In fact, the Bubble90 is currently used by the top restaurant chains in Japan, in more than 24, 000 different locations. These various customers often receive a return on their investment in as little as 6 months out of the 5 year lifespan of the Bubble90.

So you’ve probably already gauged where the “90” in “Bubble90” comes from, but what about the bubbles? Well, the truth is, it’s all about the bubbles. But to explain that, we’ll have to tell you a bit about:

HOW it works

Pulsating Flow Technology

The patented Pulsating Flow Technology is the defining feature of the Bubble90. It is the reason behind its incredible cleaning power and water-saving potential. Thanks to some engineering wizardry, only 10% of the water makes it out of the nozzle. The high-velocity water jets shooting out of the Bubble90 are actually made up of 90% air bubbles. This creates the effect of water droplets crashing down at high speeds, punctuated by air. The resulting water flow feels like a pulsation against one’s hand - hence the name.Read more >>


A normal stream of tap water spills around the surface of an object, forming a film of water that blunts its subsequent force of impact. When the Bubble90 water jets hit the surface, they land with force than much greater than normal tap water, while the large content of air prevents spilling. These two features result in a machine gun-like momentum, where water always hits the surface at full force, making cleaning faster and easier. The increased effectiveness translates into shorter cleaning time, which is especially noticeable in hard to wash substances, such as oil or chocolate.

One-touch maintenance

Cleaning and maintaining the Bubble90 is incredibly easy and requires no plumbing skills whatsoever. All you need to do is pull down the end of the nozzle and turn on the faucet - simple as that. This will flush any dirt or gravel from the inside of the nozzle, cleaning it in no time.Read more >>


The Bubble90 uses no electricity, so you never have to concern yourself with faulty wiring or empty batteries.

Simple Installation

Installing the Bubble90 is a very straightforward process. All you need to do is unscrew the tap of your faucet, and screw the Bubble90 in its place. You don’t need any specialised skills.Read more >>


We work with all the standard Japanese faucet dimensions, but sometimes an adapter may be necessary. If that is the case, our sales team would be happy to assist you.

Constant evolution

Even after the Bubble90 won the Grand Prize for “The Best Product Of The Year” in 2009, our team never stopped improving on the efficiency of the original design.Read more >>


The Bubble90 that you purchase today is the result of over 9 years of research and development, as well as thousands of hours of testing in hotel, restaurant, and supermarket chains all over Japan.

WHY Bubble90

If, however, you are interested in the underlying motives and the overarching goal I have set for this product, then I encourage you to read on.Read more >>


People have often asked me why I started working on a water-saving nozzle in the first place. The answer I usually give goes something like this: All the water-saving devices I had found were too expensive and too constricting towards the user. Looking at them, I thought, “Water saving shouldn’t be a chore. It shouldn’t demand I change my habits. Instead, it should be something profitable, something I want to buy because it tangibly benefits me.”

My other reason was the ongoing water crisis around the world. In Japan, this has mostly been felt through the steep and constant increase in water prices, but water scarcity already impacts about ⅓ of the globe - that’s some 2 billion people. If current trends continue, this number will double by 2025. While the problem is most visible in economically challenged areas, it is equally severe in large cities. Many of the world’s metropolises rely heavily or solely on ground water to meet the daily needs of their citizens. But this is only a band-aid solution, since those ground waters are being harvested at an unsustainable rate.

What happens when they run out?

In the case of Tokyo, we’re already seeing issues like land slumping and saline water intrusion as a result of groundwater depletion. Some have put their future hopes in seawater desalination, but that’s not a permanent solution either. The UAE is a country which has historically suffered from water shortages, and Abu Dhabi and Dubai have already invested heavily in such technologies. Their efforts confirm that desalination as a solution, while pertinent, is neither infinite, nor devoid of downsides.

In my opinion, the best way to solve the issue of groundwater depletion in our cities, is to not let it happen in the first place. I believe that if water conservation becomes profitable enough to facilitate a mass-scale adoption, it is possible to curb the overconsumption enough to allow the aquifers beneath our cities to recharge naturally, as they have for thousands of years. And if we can accomplish this in Japan, we can do it worldwide as well! If we manage to save the water resources of economically prosperous cities, we can develop a low-cost version of the Bubble90 and also help poorer areas of the world! This is my dream. This is the purpose and the motivation behind my invention.

Is this dream too big?

Not if you believe in people’s capacity to act according to their best interests. The biggest consumers of water in urban areas are businesses of all sizes, but especially factories and restaurants - the latter is already our biggest customer group, and the former is rapidly growing. By severely reducing our clients’ water footprint, my Bubble90 reduces the stress on local water reservoirs and other natural water resources in their communities. The higher the debit, the higher the environmental impact of the Bubble90, and also the higher the monetary incentive for the customer to make one.

Most Japanese companies have a “message from the CEO” section on their websites. I didn’t want one in ours, because I didn’t think I had anything to share. But while writing this, I realised I had at least one thing worth sharing - my dream. So here it is, “the dream of the CEO.”
