I just received my first order a week or so ago. Their customer service is very good. If you ask a question, expect a quick response.
They also have an ebay site that sells a lot of Japanese teaware. If you contact Maiko in Japan, they will discount the price of the teaware if ordered direct from Maiko instead of their ebay site.
The Japan Store
They must have just added a converter right with their yen prices. When I ordered I used paypal and converted it that way, but your credit card will handle it if you prefer. I just liked control of knowing what my conversion would be.
