How is it possible to sell via YJ?

Doese anyone know how to sell via YJ? ... Any explanations for people outside of Japan?

(Or is there maybe anyone who could sell as a proxy?)

You must have a Japanese bank account at an actual Japanese bank, for starters. That's going to be the biggest stumbling block that will prevent any gaijin from selling on YJA.

 

There are proxy services who will list stuff for you on there though. I don't remember exactly who off the top of my head since it's been a long time since last I looked. Maybe Shopping Mall Japan?
