Actually, it was a 9.0 on the Japanese magnitude scale. The quake was in (or close to) Japan, so the American scale is irrelevant.

This makes no sense.

Earthquakes in different places can be compared only on a common scale.

Looks like JMA says 9.0, USGS says 9.1. I don't really have enough expertise to know which number is more accurate, and I suspect it doesn't make a huge difference. It's in any case the highest magnitude earthquake ever recorded in Japan.

Japan gets earthquakes every day, and is much more seismically active than the US, so I would favor their expertise more. But yeah, it was the highest ever recorded. According to Wikipedia, it actually moved Honshu (the main island of Japan) by over 2 meters to the east!
