This is a much bigger issue than Konami. I really think that the Japanese triple-A game looks like it's headed towards extinction. While console gaming is still big in the west, it is essentially dead in Japan. To survive, a lot of Japanese companies are pivoting into more profitable industries instead of closing their doors. There is too much risk and money involved.
Well, there's a whole lot more to it than that. Japanese gaming moved over to mobile to suit the needs of an on-the-go lifestyle, but there's still a subset of gamers willing to buy these titles. Koei Temco is indicative of that - while their games don't break the banks, they do alright.
The real issue is finding a balance between mobile and home gaming. It's possible. I think Capcom is a pretty great example and doing better now than they used to. You have mobile games bringing up a good portion of money, and console games taking care of that shit so you aren't leaving anything on the table. If you can find a balance, it works.
(Obviously some companies can get away with not fucking with mobile ala Koei Tecmo, but that's a discussion for another day)
Couple that with better budgets, and I think Japan is finding its place better now than when they did with the PS3/Xbox 360. TGS had a huge slew of games coming out slated for next year, some of them incredibly niche. It's not as much as the PS2 days, but I do think it's getting much better.
