AHC/WI Japan continues to be the high-tech, futuristic wonderland of the 1980s?

What if by the 2010s, Japan continues to be a country that seems like to be at least 30 years ahead of the USA and Western Europe in technological development, and also completely free from the West's moral constraints, similar to its 1980s image?

By the 2020s, Japan continues to be seen as a place where all carnal desires can be fulfilled with no shame, if the person is willing to work for his/her money extra hard to pay for these services.

Essentially: "In Japan, nothing is impossible, provided you can pay for it."
 
Gonna point out the obvious: they'd have to avoid the Lost 20 Years somehow. No idea how since I'm too lazy to read up about it :^)
