Please re-read the rest of my reply.

"Diverse often means to accept less qualification for the sake of accomplishing diversity, unfortunately."

This is your opinion. It's not factual, and I'm pointing this out. There is nothing intrinsic about being more diverse that makes it lower quality or less able "to execute" than a monoculture. There is nothing about monocultures that means they are more, or less, capable "to execute" in the first place... a lot of them are just buddies hiring buddies. It's your assumption in the first place that these are efficient or meritocratic in the first place. They can be. Many businesses aren't even efficient or good at executing.

"It's not the perspectives that matter, its execution."

...perspectives are what influence execution in the first place. You need to be able to execute a plan well, but creating a good plan is also vital. Diverse perspectives catch potential design flaws and other things that can be missed by having a monoculture (any monoculture) in leadership.

I find it discriminating of you that you distrust any ones ability to do the job. In Japan there are Japanese people. Who should do the job? They of course, why not, they live there. Why shouldn't "some of them" create enough diverse views? What do you want? That people from other countries go to Japan and enrich them? Gentrify and replace them? Will they have/add better perspectives? Will they mix or integrate into the local population while providing more diverse views and creating a more diverse population (also: physically - like "mixed ethnicity babies")?
