You can try for a student visa for Japanese language school for two years. If you're willing to pay for a plane ticket to a nearby Asian country, you could probably renew it in perpetuity every three months. There are also other visas like entertainment or modelling that you could try to obtain for three months. You can even teach English part time and try to get a visa that way. As you make friends and build up a network you're certain to find a way to make it work. In practice, visas are easier for people from Western developed countries. The only major risk of overstaying a visa is getting a random stop from police and at worst you just get deported. It's really not as restrictive as it seems. I've met plenty of people who visited Japan on a whim and ended up staying for years.
