Well everyone who has worked for any major video game company has bad things to say. Read it all here, only this is for Nintendo. I left out a few things, so take a look at the link.
Cons – No layoffs means no change. Many of the management are there for 20+ year, and proud of it. Many of them joined Nintendo fresh out of college, or in some cases, high school. They do not know how the world outside Nintendo works. They do not know managers in the other successful companies are highly educated and competitive.
Because the old timers won't leave, there's no room for young talented people to move up. Many smart young people left. Those who get promotions are lazy workers who spend 50% of his day sucking up to management, lying about his achievements. Very disappointing for honest, hardworking, capable people.
Advice to Senior Management – The review in ONLY top down. No manager gets comments from subordinates. No use to complain to manager above, as they all protect themselves, knowing the limitation of their competencies. They really need 360 degree review process.
As someone who is a part of the corporate world, I can tell you first-hand that these are not Nintendo-only problems. Any company that gets large enough will have issues with Management being lifelong employees, and possible career stagnation if you don't work hard enough. These are all complains that are typical for any company that's larger than a postage stamp.
Unfortunately, networking is integral to promotion as well, and that complain sounds almost like someone who was jealous their peer got a promotion over them because they see themselves as more qualified.
One thing I can say: I'm grateful to work for the company I do BECAUSE they do things like manager effectiveness surveys, employee satisfaction surveys, 360 degree reviews, etc. It isn't a cure-all for managerial stubborness, but it definitely helps.
What I will say is that if the complains about management and NOJ being stubborn to change are true, then it's reflected in Nintendo's products.
