I got this back from Nintendo when I emailed them:
Dear Customer, thank you for your e-mail.
I am sorry that you feel disappointed but Nintendo have no control over the amount of import duty that is imposed, the sales tax (VAT) that is imposed, the transport costs to get product here from Japan, the distribution costs to individual retailers or the amount of profit margin demanded by them. These have to be paid by someone and unfortunately it is the customer
Kind regards,
Your Nintendo Team
