It sounds like a lot, but there's about a hundred yen per usd, so in govt budget terms that's single digit billions. Still, it's Japan, so it'll probably be used judiciously.
There is not "about a hundred yen per usd".
Awesome how almost every time I see almost anything asserted on HN within my areas of expertise it will reliably be dramatically incorrect.
USD/YEN > 150
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.
