> I'd spend a year in Japan just to see what it's like

There's laws and shit about that. You can't just immigrate to a country illegally.

You can however signup for a long-stay tourist visa, which lets you spend a year in Japan

with enough money, anything is possible

		2m isn't going to make Japan allow more than 6 months of stay in a year on a tourist visa. It might be enough to hide yourself from deportation, though who knows what happens when you try to leave. It might be enough to convince a local to get into a sham marriage for spouse visa sponsorship.
