Kokedama transaltes to "moss ball." Koke meaning moss, and dama meaning ball.
"Kokedama is a form of Japanese garden art that is centuries old and tied into the practice of bonsai. It is an accent to that mode of plant display where a moss ball is the focal and supporting point for a sculpted tree or plant."
Upon receiving your kokedama, soak it in water for 30 minutes. You can fill up your sink or a bowl or bucket with a few inches of water, enough for the moss ball to become completely saturated. There is dirt inside the moss ball so don't be alarmed if the runoff water is brown or green. After soaking, drain water and let your kokedama sit for a few minutes until all the excess water has run through. Hang it back up or place back where you had it and voila! Do this once a week to ensure your kokedama thrives.
