Sorry didn't see this. There are very few trains that stop at AEON Mall (Tokoname Rinku) station. They go from the Centrair Chubu Airport terminal at 22, 24, and 52 every hour. The trains from Tokoname Rinku leave on the hour, at 23 after, 30 after, and 53 after the hour. There might be a couple more but there are few. This was all I could find today on the internet. But, you can pick up a paper schedule at the airport or at Nagoya station or maybe at Rinku Tokoname. I am enclosing a Nagoya to Chubu and Chubu to Nagoya schedule. It is better to keep shopping, leave 6 minutes for the walk to the train station, get ticket, at AEON at the food end near the terminal, because, in the winter it is a very windy platform if you don't have a hat and a scarf.
