A very practical question regarding Japanese electricity supplies

[Jasper Sharp]

Hello fellow Kinejappaners,
My gosh this list has been quiet of late. I hope there's still a few people
out there who can answer my question.
I am heading off to Japan for two weeks with nothing more than a rucksack, a
railpass, a rendez-vous in Kyoto and a video camera, the last of these
things being the problem. Having bought the thing in Holland, it is PAL
standard and will need recharging according to European standards. So, does
anyone have any experience about recharging or electrifying European things
from the Japanese power supply? Can I buy an adapter here in Holland or is
it better to get in Japan. I will also need something to charge my minidisc
player as well (essential, obviously...) 
And whilst I'm on the subject, I have two weeks and aside from Tokyo and
Kyoto I'm wondering where else to go. As I mentioned, I have the railpass,
so I basically have the freedom to go where I want within those two weeks,
and after the big cities I'm rather tempted to get off the beaten track a
bit and practice my elementary Japanese, hopefully somewhere a little
cheaper than in the big city. Hokkaido appeals in this respect, but I think
it might be a little too far to get to in the time I have allowed myself.
Any other suggestions?
Look forward to hearing your replies,

Regards,

Jasper
