Which side is your gas tank filler on? Don't look back.

36. I believe it's on that side because it was built for the Japanese market

Just like many minivans have the rear door on the left, opening into traffic here. Your filler was designed to be on the driver's side for when someone pulls up on the left side of the pump.

There's another way to tell where most of your car model was sold. In the rest of the world turn indicators are required to be amber, but cars intended to be primarily sold here will use one of the brake lights to signal a turn. I can see the Euro/Sino rule to be far better because it still uses two brake lights at all times. It's safer.

Now you can go out and look.
