Gatland said: “It is good to have the full details announced as the excitement for the tournament continues to grow.
“We have spoken recently about our aims and belief for 2019 and how our focus on the next two years is to provide a platform for us to peak in Japan. With this announcement we can continue our planning and preparation for the tournament in finer detail.
“We kick off the tournament against Georgia before facing Australia, both of whom we play this November in Cardiff. We then have a good block of time before facing Fiji in Oita, before the short turnaround before our final pool encounter versus Americas 2.
“We have four cities to visit so it is important we buy into the culture of Japan and the tournament.”
