Hi, fellow YTer~
I do read Japanese and kinda browse through the website.
It seems like the "Happy Market" (how the website's name directly translates to) states that they don't offer international shipping at this time.
As for
http://www.prettyyoko.com/, I have personally ordered from them before.
One of YTers posted this site here long time ago, & I ordered some clothes & 2 beds & feeders for my baby girl.
The shipping was fast and I didn't have any problems w/ them.
(It's just that the shipping for the bed was pretty expensive.....)
I don't think
http://www.prettyyoko.com/ sells knockoffs~ since that website is linked through
http://www.creativeyoko.co.jp/ (lower left hand side at the end of the page)
Anyways, hope it helps.
(My baby girl is the 1st yorkie I've ever had, so I've never actually "helped" here on YT when pll have questions regarding yorkies' health issues or things like that, and it feels good that I can finally offer my help somehow.
)
