You cant order from there as long you are not using a japanese ip adress which might only work if you are sitting there
You get redirected according to your countries IP adress Origin Store Page if you try to use the Japanese Store..
And even you manage to use a japanese ip adress, i am not sure if you can purchase at the store with your CC if its not asian..
In my opinion, the only way would be to have a friend in Japan, purchasing the items there for you, sending you the codes and you use it on your shard..
And even than, i am not sure if you can use the codes lets say on Atlantic - might only work on a Asian shard...but i couldnt try this yet..
Wouldnt be that bad, just had to make a char on tha Asian shard, put the codes in, transfer the char to your shard you like...
Maybe try with some of the broker sites if they can get you this chest...but it wouldnt be cheap thats for sure hehe
