I don't expect a resurgence in Japan anytime soon.
They have the lowest fertility rate in the developed world, with a combined (male + female) median age of approximately 46.5, the oldest in the developed world, whilst also continuing to age the fastest (although may soon be overtaken by Taiwan).
An economy that has long been in either a state of recession or stagnation, coupled with the aforementioned demographic issues that are only going to get worse, there is no recovery in sight.
The country may have a population of ~128 million people, but the break down and the trends of demography sure aren't favorable for a market that relies heavily on the intake of previously unexposed people (i.e new generations).
Japan is dead, for the foreseeable future. I'm sure this will come across as a controversial opinion to some, given the ultra-left views of some members on this forum and the hatred for anything that might be considered conservative (like... breeding above replacement rate), but it's a genuine factor in the death of the industry in Japan that I don't think is often considered. The console market always has a chance to be revitalized in a country that's been as tech-savvy as Japan, for so long, but the rate of population replacement simply hinders that potential.
