|Where||In a cavern behind the Waterfall|
|Opened||November 16, 2010|

The dojo itself was positioned on a large chunk of mossy rock, supported by chains. There were a series of streams that poured down from above onto the floor of the Water Dojo, which then were poured deep down by two small waterfalls in the corners of the dojo. There were two statues of Water Ninjas, and a raised platform where Sensei resided.
The Water Dojo first opened on November 16, 2010. At this time, like the Fire Dojo before it, construction was in progress, and a hunt for water was put in place to tame the waterfall the dojo was located behind. After the hunt and construction ended, Card-Jitsu Water training began.
- For a week after the Water Dojo was completed, there were many blue lanterns hung up around the Water Dojo, and two blue banners, which had the symbol of water on them.
- When snowballs were thrown here, they turned into water balloons.
- Originally, the whole Water Dojo would slowly sway from side to side, due to the chains. In 2011, this was removed, and the dojo remained stationary since.
- As seen in and according to the description of the Card-Jitsu card Water Party Sketch, the Water Dojo was originally going to have plants, small fountains, and even hot springs. According to the card's description, they were removed to make the room look more intimidating, to reflect the environment and challenge of Card-Jitsu Water.
