LOL. From your wording and questioning, my guess is that you have been reading too much Meditation from a Western cultural perspective. And I would not be surprised if most of them are indeed, Scams.
My suggestion would be to travel to Japan and find the answer for yourself.
Honestly, its a scam in Japan as well. It is really really hard to find something that really works given most people have swung towards being apolotical & agnostic. Shintoism is carried forward as a legacy not because people actively believe in it. Zanzen or "zen" Buddhist retreats charge a ton of money and make you go through a mindless routine. And its a make-believe that you learnt meditation.
Being a functioning Buddhist, the only thing I can say it takes months to years of everyday mental training to bring that discipline. I tried with some degree of success but it needs more time for legendary results that people talk of.
