Is this really specific to Japanese air conditioners? Or is this really about mini-split ac that are manufactured around the world under many companies. I don't see whats specifically Japanese outside of the person using Panasonic and is in Japan. The person could be in the USA with Mrcool mini split, it would be a similar article. Edit: title has been changed to remove mention of Japan, so my nitpick may no longer valid:)

I've never seen an apartment building in the US with special pipes for running the refrigerant lines. It's just not feasible to install a mini split in the US if you're renting, but it appears Japan is totally set up for it.

  Impossible to live without AC in Japan. Also almost every move company can remove/install AC's pretty easily so it's kinda convient. Also if all rooms already have installed AC's then apartment rent price is much higher than similar without it so it's 50/50 what you want.

    It's the same in many parts of the US, but unless the apartment comes with central AC, we're stuck with noisy and inefficient window AC units[1], or worse, portable AC units[2].

        Even in rural area, temperatures in this August is sometime 36-40C (or even high) so cooler is mandatory.

He uses the Echonet Lite protocol[1] and says that it is a home automation protocol used in Japan. So that whole second part is Japan specific. I agree that the rest probably isn't. 1. https://echonet.jp/hems_en/ https://echonet.jp/hems_en/

It's not uncommon for renters in Japan to provide the AC unit, the washing machine, and other appliances. The plumbing is already there for a split AC unit, but the appliance is not.

  Air conditioner is now almost mandatory equipment for condominium meanwhile washing machine and refrigerator is an offer from some condominiums.
