I bought on Sunday from UK - it was listed as ¥6500 (roughly, can't quite remember) but when added to basket that changed to ¥7,087.
Shipping was ¥1,851, plus I paid for gift wrapping ¥314 (following above advice so it's guaranteed to be shipped in a box).
Total = ¥9252 -> £60
On the Amazon invoice (which is in Japanese so not the easiest to make out...) underneath the breakdown of costs I just mentioned, there is an additional section which states the "Tax Rate" (20%) and "Total Tax Amount" (¥1542 -> £10.25). I'm unsure whether that is already included / not required to be paid for, or whether this a separate cost yet to come - I'll keep you updated, but I'm sure someone else here might know better - this is my first time ordering from Japan!
