It used to be roughly that not too long ago, so it's not surprising that that's still the exchange rate people have in mind. I don't think it's worth making an issue out of or being upset by.

A 50% difference is substantial

Still single digit billions, as I said.

A dollar goes a lot further in Japan. Wages aren't inflated, workers are more efficient, and government waste is highly scruitinized.

I had a look at trends over time (https://www.macrotrends.net/2550/dollar-yen-exchange-rate-hi...) and looked back by decades. In 2013 it was 97.6, in 2003 it was 115.94, 1993 it was 111.08. So roughly around a hundred yen per usd. Before that it was 237.55 in 1983.
