My goal here is to disassemble Patrick's choice, learn from it whatever I can, try to make a prediction about the effect of that move on his life, see what Patrick thinks about the move to Tokyo 1-3 years later and learn again.

So far I think the move would have slightly negative impact, mostly because increased cost of living. That would force Patrick to deviate from his goals more, do more enterprise consulting (as opposing to product development) and add more stress to his life.
