Typically Japanese cars have indicators on the right, wipers on the left,
the opposite to most cars.

However, more modern Japanese cars are following the standard convention of
indicators on the left

I'm guessing that more modern Japanese cars are being manufactured in
Europe, hence the change in positioning of controls on those models.
Overall, Japanese cars seem more standardized with positioning of
wiper, headlight and other controls. Although European manufacturers
seem to have standardized on indicator positioning, the rest of the
controls still vary between manufaturers, and even models from the
same manufacturer.
