I’d say it’s more because they’ve established a reputation and they’ve kept it up, which is were Japanese culture really shines. Compare it to, say, Blizzard, which cashed out and pissed its reputation away mostly. Sure, Japanese companies will try to cash out sometimes, but if there’s the possibility of them losing their reputation because of it, they will back off even at a loss and try to make up for it. Do not confuse with South Korean companies, by the way.
