I'm not terribly knowledgeable about cell phones. The edge looks exciting and I like supporting gadgets that are powered by open source, but I live in Japan. Could somebody point me to online info that would let me know whether or not I could use this device to make phone calls here in Japan?

This question appears to be off-topic. The users who voted to close gave this specific reason:
"The Ubuntu Edge is an open device, not locked to any particular network. It works in all countries that provide GSM/3G/LTE-based network services", I quote from the project site. From that it is clear you can use it in Japan with any network that provides GSM/LTE services.

I hope that is what you are asking for.
