If you ever travel by car up this way, it seems like it would pay to buy stuff and bring it back. Have you checked
Yahoo!オークション ? Might be a place to find something. Also may try looking for petroleum companies that might sell ethanol. But seriously. You might have to talk to a car place, or just stock up during winter. Buy a 20L kerosene container to hold the mix, and just pump from it. That's what I have right now.
