This mat has received unjustified bad reviews. The person who complained about it being green should have realized that this mat is made of fresh rush grass in order to be flexible enough to weave. Anyone who has ever ventured outdoors knows that fresh cut grass is green, and this grass will remain green for a number of weeks. Thus, any fresh tatami is going to be green when it is first received. And of course, until it thoroughly dries, it will also smell like the lawn after it is mowed (to address what the other poster said about the smell). Unfortunately a lot of people are uneducated about these mats before they give them poor reviews. I put this mat outside in the sun for 3 days, and it turned a beautiful golden brown color like my other goza have in the past. The quality of the weave and the border is very good, and the price simply cannot be beat for a fresh finished goza mat. I will be purchasing more.
