No. There were no US Einsatzgruppen, there was no US equivalent to the nazi Backe-Plan.
The US occupation of Japan was remarkably benign, for a country concerned with "systematic and indiscriminate extermination". You may wish to contrast this with, say, the behaviour of the Japanese Imperial Army within the Asian-Co-Prosperity sphere, which, while not really engaged in genocide, had a habit of large-scale massacres, gang rape, torture and enslaving the local Asian population which they considered as inferior, for all the propaganda about freeing Asia from the white man's rule.
If you really want to see what a blueprint for genocide looks like, I invite you to read about the Nazi Hunger plan [1]. Nothing the US did was even remotely like this.
