I have the latest model Mitsubishi whole home dehumidifier that keeps the air at a constant 50 percent humidity.

Could you post a link? Sounds interesting

Sure! This is the model:

I searched kakaku.com to find the best deal and ordered from there. I paid about 77,000 yen and I'm very satisfied with it. The tank is large and holds an enormous amount of water. I empty it once per day into the kitchen sink but it has the option of a hose attachment which can pipe the water to your washing machine basin instead.

I have the latest model Mitsubishi whole home dehumidifier that keeps the air at a constant 50 percent humidity. This is ideal for human comfort and eliminates the moldy or musty smells that tend to creep in once humidity surpasses 60 percent. In my bedroom I keep the AC at 23 degrees constantly (never turn it off) and I sleep very well.

I can't imagine how anyone could use a humidifier during the Japanese summer. Was that a typo?

No typo here! Obviously you don't seem to need it in your situation. Like you say, it's only beneficial if your AC is drying out your air to below 50%; otherwise it would be somewhat crazy.

Ah, that makes sense. I tend to think that the humidity level in my "manshon" is high because I'm cooling it which causes the relative humidity to increase since cooler air holds less water. At 23 degrees it naturally seems to be at 60-70 percent RH but drops to 50 with the dehumidifier. When the AC auto-cleaning feature kicks in the room temp briefly goes up to 28 degrees and the hygrometer plummets to 30 percent RH which does feel dry.

My partners parents have been sleeping in separate rooms for decades and swear it's the secret to a long marriage.

We've been doing the same. Of course having a room each is a luxury I guess many don't have, but you can read in bed as long as you like, use whatever blankets and air-conditioning you like and not worry about when your partner wakes up and/or their snoring.

I've also set up some heat sensors and home automations with an infra-red blaster which really helps keep the office just right. Nights still aren't so hot that I've had to do that in the bedroom yet, but I plan to. The remote controls timers are terrible, but using home assistant and node-red you can program a series of rules to automatically turn on/off or adjust your aircon.

We use a queen bed with 2 blankets - Get one of these for yourself!

Thanks for this tip! Which one do you use, the ultra cool? Does it keep you cool without having to use an AC at all?
The AC in our bedroom is broken and we had to replace two others in the living room and in the wife's "office" last
summer, so we are kinda putting off another big purchase. Running a fan all night causes weird cold-like symptoms-runny
nose, dry throat, etc., so this blanket idea might be the best way for us to make it through the real heat that is coming!

I have just finally purchased a 4LDK house in Kanto and I'm hoping that there might be some alternative or compromise on the heating/cooling that I have to install for energy, budget efficiency.

We'll mostly use the LDK, bedroom and office, and 2 rooms will be fairly empty for awhile. I am more tolerant of temperature for my home office, I think, so maybe only 2 rooms at this point need those good quality heating/cooling units installed right away. Any recommendations for those? Or, do I just bite the bullet and install in every room from the start? Then, walking around Tsutaya Electrics in Futago Tamagawa had some cool stuff in there and various fancy new space heaters so I thought there might be some cheaper alternatives for the home office and extra rooms in case of guests, but still would need some kind of basic cooling in the Summer too.

I doubt if it’s worthwhile installing units that will hardly be used, but you could ask for quotes with and without, see if anyone will give you a better deal for more work.

For the office, if it’s just you it’s not really necessary to heat the whole space. We have a couple of electric powered carbon heaters which are not horrendous costwise and do the job of heating you up if you stay reasonably close to it.
