That's a cute little radio. I like hand-cranked radios.
One limitation to keep in mind with this particular radio is that in Japan, the FM band only spans 76–90 MHz instead of 88-108 MHz in the US. You can see the frequency spread in the photo. You can see TV channels 1-3 also, but that still won't give you US FM reception up to 108 MHz. I think AM is the same, though, so for emergency use and listening to your local AM news station, it should be fine.
Maybe they'll have a US version.
