The kind of software in keitai (feature phones), car ECUs, and video games is different from the rest of the software industry. They’re good at making gadgets with embedded software and nothing else. In particular, nothing ever gets reused and nothing is ever made more abstract or flexible - that’s why most of the products can’t be exported and the iPhone killed all the Galapagos phones.

There are a lot of interesting lessons in video games though; it’s the only kind of software people love using enough to write emulators for, and game developers seem to exist in a lot more countries than other software businesses do.
