Arm Spirit, as I'm sure you can surmise, is an arcade arm wrestling simulator. Atlus has now recalled these machines (150 in total), after 3 cases of players breaking their arms. Anyone played this particular machine? I've played a few of these in the states, and they were never strong enough to break my arm. Although Atlus' spokeswoman says that these aren't either, so...

they're all weaklings. i would break the arm of the machine! so then they have to recall those machines in the other way.
According to this source (in Japanese) among the 3 that broke their arm/hand there were one tourist from France and one from South Korea. Not that it means anything though...
I remember almost breaking my wrist punching the boxing arcade game, Sonic Blastman or something. Ouch. And I'm not limp wristed either.
