Any "evidence" (or anything substantial) about your hypothesis? Like, did Japanese companies actually invent inverters, or are inverter air conditioners more common in Japan compared to other countries?

Sorry for bad English, "develop" would be better word than "invent". AFAIK Daikin argues that Inverter Air conditioner is very popular in Japan compared to other developed countries. In Japan, mini-split type a/c is common and almost all producs are runned by inverter compressor (except very cheap one but almost no one buy it). Here's Daikin's argument (japanese). Green is % of inverter and Japan is 100%. https://www.daikin.co.jp/csr/information/lecture/act01.html https://www.daikin.co.jp/csr/information/lecture/act01.html https://www.daikin.co.jp/csr/information/lecture/images/act01_image02.gif https://www.daikin.co.jp/csr/information/lecture/images/act0... It seems that world's first inverter a/c is by Toshiba. https://toshiba-mirai-kagakukan.jp/en/learn/history/ichigoki/1981aircon/index.htm https://toshiba-mirai-kagakukan.jp/en/learn/history/ichigoki...

  Thanks for the links! I do found that inverter AC seem more popular in East Asian countries. But then again, they don't use central air conditioning in residential as much as the US do, so probably not an apple to apple comparison.

  My parents have an inverter mini-split. It’s amazingly effective at dehumidification. If I ever have to change out one of my AC units I will probably go with a multi-zone mini split. Being able to condition only the rooms that are in use and the super effective dehumidification the systems offer are a significant upgrade over traditional ducted AC systems. Heat pumps on mini splits tend to be far more effective too.
