So, I just returned from Japan (Tokyo, Osaka, Kyoto, Kobe, etc...)  I must say the survival phrases 1-10 were amazingly helpful, I recommend them to everyone.  I am continuing to study Japanese now that I am back in the US.
I bought a Japanese appliance and need to find a step down travel converter.  It needs 100v 200w 50-60Hz.  I should have bought a travel converter in Japan, for travel to the US.  I need to find one here in th USA.  I am hoping someone has dealt with this in the past.  I know they have small ones, but alas my internet searches only found larger oversized transformers.
Thank you in advance.
