Japan has a bunch of solid long running studios.

Earlier in my career I worked with a game director who had done "major arcade franchise which is now a console franchise". He had the same employer and similar co workers since the early 1990s and was coming up on retirement.

Nintendo is the obvious example but there are many others. Japan benefits from other jobs being less competitive work/life balance wise so games are if anything a sweet spot. Plus a focus on stability, which brings stability.

The methods are simple but involve defocusing shareholder returns. Hence how Nintendo has Miyamoto as an executive while Tod Howard is not an executive of Xbox.
