Kangen water is created by a Kangen water machine manufactured by Enagic, a Japanese company, it is not as the name suggests some rare form of water from the planet Kangen, or a natural stream running through mountains, Kangen is a brand name belonging to Enagic.
Kangen water is alkaline water, many different manufacturers make alkaline water machines which are known as water ionisers as its ionisation of the water that makes the water alkaline, but only Enagic can call their machines a Kangen and their water Kangen water.
So to answer the question directly now you have the background Kangen water is from a Kangen machine that is manufactured by Enagic, thatís not to say that you canít get alkaline water which is what the Kangen machine produces from other alkaline machines but you can only get the Kangen brand of alkaline water from a Kangen machine.
Kangen water machines are expensive, over £3,000 for the SD501 which is recommended the most by independent distributors, only these distributors sell Kangen machines and they sell the machine on a commission basis, so some of the money that you pay for the machine goes to pay the distributor that sold you the machine their commission and also the distributor that sold the distributor that sold you the machine a commission too, this is called an upline and this network marketing or direct sales is how Kangen water machines are sold.
You canít buy a Kangen water machine anywhere other than from a Kangen distributor although, sometimes your see second hand machines or as new machines being sold privately online, but you can buy a machine known as a water ioniser that makes alkaline water (the water that a Kangen machine makes) from several suppliers online and much cheaper than a Kangen machine because these other water ioniser distributors are not paying commissions.
Kangen water machines can produce a range of different waters, not only alkaline water but acid water too and to different strengths, the different strengths of alkaline and acidic water are good for different things from drinking water to washing your vegetables, to using in cooking to using to remove makeup and wash your face, other cheaper water ionisers may have a fixed alkaline water pH, but still the other brands of ware ionisers tat can vary the pH of the water are less than one third the price of a Kangen machine.
