Anpanman train over the Seto Bridge

We’ve seen pictures of the Anpanman train that goes over the Seto Bridge to the mainland. My son loves Anpanman right now so he'd be thrilled to be able to ride it. We're staying in Kagawa. How do we get tickets?

There seem to be three lines with a Anpanman train. So I'm not sure which one you’re talking about. The one that goes over the Seto Bridge runs from Okayama on the mainland to Matsuyama station in Ehime. In either case, you’ll need to make reservations online. http://www.japanvisitor.com/japan-transport/anpanman-train
