Now back in the 80s? Back in the 80s, despite being aligned with the West, they were perceived a lot like China is today. Everyone was scared that they were going to start eating the West's lunch and various negative stereotypes and exaggerations started to bubble up: it was a futuristic land, but a futuristic land of suicides, with little drone-like salarymen crammed into little shoebox apartments the size of a Western bathroom, working 20 hour days.
Between the Plaza Accords and the bubble bursting and decade after decade of Lost Decades, the Japanese threat was successfully neutralized. I think Cool Japan is mostly something they've earned for themselves, frankly.
