Just a few weeks back they announced the opening of their english site to cater to overseas customers. Previously they had been focused only on selling to local Japanese customers.
I had already ordered something from Amiami in order to write a review, so far I had found their customer service to be very friendly. Their stocks for Gundam model kits however are quite limited. I was hoping that they migrate more products from their Japanese site to the English site. Of course I also have to mention that their prices are quite competitive.
