Are they? They are crazy here so I can't imagine the US being much worse. It will be over ¥3000 for a movie most of the time. Maybe more. At the current exchange rate, that is crazy enough, but back when ¥100 was $1, it felt even more insane.
Prices for streaming are more normal, but if you want to then buy that movie on DVD? You are looking at ¥8000-¥9000. Insane doesn't behind the cut it.
$80 for a DVD? wow
