In Japan, "washed river sand" is more like what we call pumice.  It's volcanic.  Very light.  Rounded.

Herman they use washed river sand because its readily available.  We use their substrates because they are successful with it.  They use their substrates because that's what they have available and it works.  In reality, we have readily available, inexpensive substrates here that work too.  Using inorganic substrate takes the guesswork out of that part of the equation.  You know what you have and what you need to add, it drains well and won't rot.  Organics in your soil will work very well so long as you know how to handle them, and unfortunately many people don't understand them.

So, imo the soil is not the difference you are looking for.  It is a factor, but not the factor.
