^size 11 is probably too big in Japan. I think you're right, they go up to about 9.5 or 10.
Kato is easily available, they advertise heavily in Free and Easy.
Restir sale is happening now, if you like the fashunz:
I have a couple packages in hand now, gotta weigh them out for an accurate shipping cost, and then I will collect payments and ship them on. First proxy shipping run.
Magazines are available but it's not wise to buy them unless you want them shipped surface. They're just too heavy, a Japanese magazine weighs at least 500g if not almost 1kg @ 300 pages or so. Clothes weigh a lot less, usually - jeans are about 500g and outerwear goes up to about 2-3kg for the heavier stuff usually.
As it costs about $10 to get into the shipping to start with and goes up from there, you can amortize that cost by getting at least a couple items - that way you don't pay so much just to receive one item. It's more pleasant to pay $40 and open a package with two things for you (no matter how cheap or expensive they may be) than to pay $30 just for one thing, IMO
let me know if you guys need help browsing through a website or something.
