I am currently in Japan and I am going to Mandarake. I can take some orders for Johnny fangoods and Doujins from various bands.
Mandarake sells Doujinshi and a lot of fangoods from old concerts and some other stuff like pamphlets and magazines, but it's not sure that I can get things if you search for something special.
I can also offer to buy shop photos, since we'll visit Johnny's shop.
If you are interested leave a comment here, and I will contact you.
Costs for this:
Price of the doujin/fangood + Paypal fee + Shipping + 500Yen fee.

Leave comment or write me a PM with following information:
Fangood (Concert, Band etc.):
Money you want to spend:
Payment must be made before I go shopping, you get everything refunded if I don't find what you search for of course!!!
Maybe I can help you with finding some stuff :)
