I spent yesterday working with a translator to provide a Japanese interface for Quiz Edition. It strikes me that it's been a great use of time - in a single day, I've added a large new potential market.
And I'm particularly excited by the Japanese market. Generally, Japan is poised to do exceptionally well in the coming decades. I think its financial markets will suffer with the rest of the world in the short term with the inevitable return to a 'real economy' (as opposed to a 'financial services economy').
With the US looking down the barrel of deflation/stagflation/hyperinflation right now, Japan has been emerging from a 15 year deflationary period, stronger and leaner. The emerging Chinese market is on Japan's doorstep and with an emphasis on honesty and productivity, it's in pole position for a global rebalancing.
