I assume you're getting those numbers from Yahoo Finance.
They don't make sense. I'm assuming their figures are wrong because of incorrect input of data somewhere along the line.
http://ycharts.com/companies/NTDOY/enterprise_value - current enterprise value $7.974 billion
http://www.infinancials.com/en/financial%20ratio,Nintendo%20Co%20Ltd,90524FJ.html - current enterprise value $8.123 billion
Enterprise Value = Market Cap + Debt - Cash. Nintendo's Debt is about zero, and it's Cash (according to Yahoo Finance) is about $10.74 billion...
https://www.google.com/finance?q=ntdoy&ei=EWnkUujXD4XBkAXiyAE - Its Market Cap is $18.54 billion according to google. That puts its Enterprise Value at $7.8 billion.
I assume that what's happening is Yahoo Finance is working only on shares available outside of Japan, which is limited, as I understand it. And this is resulting in it calculating a market cap of $2 billion, rather than $18.54 billion.
