There is one thing that I've seen and heard Japanese and Korean companies having over Western ones: a lack of infighting and turf wars. Everybody pulls in the same direction for the most part. That part of their culture is a really strong suit - it's not only the capable individuals.
If I didn't know better I would think you were trolling. Japanese companies absolutely have infightings and turf wars the likes of which make western ones look like child's play.
Toshiba literally hated their NAND flash division (former Toshiba Memory, now Kioxia) despite being one of their only consistently valuable assets.
Sony Interactive Entertainment (SIE) despises Sony Music Entertainment Japan (SMEJ) because SIE perceives SMEJ with its subsidary Aniplex to be encroaching upon their core business of video games.
Subaru for the longest time brushed away their team working on EyeSight, now a standard feature and widely heralded, because they perceived the guys working on it as infatuated dead weights.
ANA and JAL loathe each other (also with a healthy mix of commercial vs. governmental rivalry due to their history) and will drag each other down at every turn.
I can go on but I think you can get the idea: Japanese companies really do not like playing together.
