Owning a western style BBQ

My wife and I just bought an akiya in the countryside of Okayama. I very much look forward to barbecuing every single time we are able to head out there over holidays and weekends. My question is, does anyone here have experience buying a western style gas barbecue? I've seen them for sale at Costco and online, and have used them when "glamping", but my big concern would be refilling the fuel tank. Is it propane? Kerosene? Where can you get it refilled? My experience back home has been big white cylinders of propane that you can take to the local hardware store and have refilled. I don't need anything too elaborate, just a simple gas fueled barbecue for simple cooking.
