That simple conversion formula doesn't really apply anymore. Japan is in deep recession right now and the yen has dropped sharply against the dollar in the last few months to $1 : ¥118 at the moment. It's projected to go as far as $1 : ¥130 by 2016 and $1 : ¥140 by 2017.The amount in US dollars will depend on the conversion rate in April (since most places won't charge you until then). My general rule is to go 2 decimal places over, so 6,296yen would be around $62.96 (then you'll have to take a guess with shipping).
You can get Figma Lucina for only $44 on NY for example https://www.nippon-yasan.com/figures-others/10130-fire-emblem-awakening-figma-lucina.html
Next few years are going to be amazing for figure importers.
