I guess they don't understand 'hand-waving' to communicate things like 'where are the all the wall warts?' I had to ask my wife to translate for me, I really was trying to avoid that so I could think I was fitting in here.
I scored a SONY AC-E45A at Bic-Camera for 2500 yen. I don't know if there is anything special about it other than it saying it can handle 100-240 50/60Hz but I bit the bullet and got one (they are like $20 in the US). It reminds me of the lappy computer AC-DC adapters that are worldwide, the only thing is there is a flip out, fold away-plug on the adapter itself; not so much a wall wart as a wall slug. You gotta get another plug adapter to make it fit those funky 220-240 plugs. I didn't want issues with the M1 or the charger or anything I plan to use it for (CD player and whathave yous).
Maybe I am paranoid. I don't know alot of ins and outs about living in Japan yet. I would be happy to hear any suggestions on places to buy things here...like a Rat Shack equivalent for starters. One thing is they don't use CCs that extensively, so I gotta pack a wad of bills anytime I go anywhere. $100 (10,000 yen or ichimon yen) flies from my hand faster than you can say 'youpay-now'. On the other hand, the ramen and udon noodles are amazing and pretty cheap.
