Which is why one experiments with different sums, and starts small (though it's also possible that wishing for large sums causes only minor things to break, whereas wishing for tiny sums causes great catastrophe).It may be possible that whatever his wish is might affect what breaks in exchange, so wishing for money may not break something that bad, but wishing for large sums of money may do so.
Sure, but that depends upon the aforementioned relationship. It is very likely that he can successfully wish for ¥1. Wishing for ¥100,000,000 might cause fatal damage to his body or such a wish might be denied.Maybe even wishing for more money than he himself has is impossible, because he doesn't have enough property to break in exchange.
I suspect that @Luijs's suggestion would be another one that was simply ruled-out. And it's worth noting that it would the wish would need to be more carefully stated, as there are things that one actually wants to have broken.But clearly @Luijs is way ahead of all of us in thinking of a way to game the system.
