Depends what wall voltage they use in Japan. America has 110v coming from its outlets while Europe uses 230v. I haven't the faintest on japan though. :?

Japan uses 100V mains so no.... Japanese adapaters are NOT suitable for use in the US. US voltage is 120-125V these days where I live. It's been creeping up for decades a volt or two at a time. Running a wall-wart at 125% is asking for meltdown.

As a side note.... depending on what island you're on, the power is either 50Hz or 60Hz.  

That's the great thing about standards.... there are so many to choose from.

Take care,

Do you mean some DC jacks and plugs diameter?

Some japanese equipment commonly used ones that were just a little different size than some common european ones, like european common was 3,5 mm and japanese used something like 3,8 mm (dunno if I remember the numbers)

It was just so small difference you could not easily see the difference, and you could plug a 3,5 mm to a 3,8 socket, but it was not so reliable...

And you could stuff 3,8 to 3,5...

thanx for the replies.
  here's he deal:
    i have a cliet in sweden that wants to use the device in japan most the time. i need to find the right adapter. all my pedals can run on a "boss" type adapter.[ 9v 200-300mA, input:120V~60Hz6w , type thang ]
   maybe i should contact roland/japan?

One way around that is to use a US adapter that still puts out enough power when run from 100V at 50Hz (the plugs are the same Edison style), just don't try it the other way around.

An adapter that puts out 12V in the US should do the trick nicely.

Good luck!

thank you peter,
  that's just what i have

it's 100V 50Hz/60Hz east-/western Japan. Two-prong non-polarized plugs are standard (most outlets are two-prong I guess the same as the old U.S. standard??), FWIW.
