I guess Japanese society values stable trajectories in life more than money, whereas in the US the common trope is "you work for someone — you never get rich" and since getting rich is the only definition of success we have this hustle culture.
I even noticed this with a black and white picture of some AI startup group picture google bought. It looked exactly like a band picture from the 90s. Everyone all serious looking, different fashions, the lead singer/ceo a little bit more forward and center in the photos.
Another amusing cultural thing is I remember the saying like "even CEOs of big business want to be in the music industry".
Now it is the opposite and even the biggest music artists in the world want to be CEOs.
