Mt fuji is 20% taller than than Mt Tate in Central Japan. 

It is several orders of magnitude more famous. Not 20%. Have you ever heard of Mt Tate, or the other "100 famous mountains of Japan" besides 3 or 4 active volcanoes in the news? Mt fuji is an internationally recognized symbol. Though just ~800m taller, it is probably the only mountain most people can name from Japan. It should have its icon rendered as soon as the label for Tokyo is rendered - it is arguably as well known. Same with Denali, vesuvius, Everest, Kilimanjaro, The Matterhorn, and other iconic mountains from around the globe. 

Mt Akagi is ~40% shorter than Tateyama. It is also more famous. But not 25% as famous as mount Fuji

your suggestion to use elevation as some substitution for what z level a mountain should have its icon/label shown breaks at the most fundamental level on first attempt of application. 

Please think it through and try again. 

Mt Fuji - 3776m -Internationally iconic. 
Mt Tate ~3000m - regionally famous 
Mt Akagi ~1700m - nationally famous. 

Hill near my house - 25m AGL-  not important.
