Takes 6 days usually from Japan to me here in YYC.
Problem is, when you order from Yamiya it's so exciting (cause your you know your getting the cool jewellery) that the 6 days are very loooooong.
There is a Shipping option from Japan called SAL, I beleive it stands for Surface Air Lift. It's about 1/3 the cost of the Air Priority that Yamiya uses, and it take 2-3 weeks for stuff to get here.
I wish Yamiya offered SAL shipping, it works well. No tracking number though, that's probably why they don't.
