How to use the Air Conditioner in Japan?

How to use the Air Conditioner in Japan?

The main kanji on Japanese air conditioner remotes, plus extra buttons on fuller models.

The summer in Japan is very hot and rainy, and many people end up suffering from heatstroke. A great lifesaver is the air conditioner, however some foreigners who encounter it feel lost with those words entirely in Japanese. Of course, there are air conditioners from various brands and different types. Knowing the main words written on a remote will help you use it.

Each remote control is different, so it is pointless to put a photo here indicating each button. What we can do is present a list of words that are present on remote controls so you know what each button does.

JapaneseHiraganaRomajiEnglish
停止ていしteishistop, turn off
運転うんてんuntenturn on, operate
冷房れいぼうreiboucooling
暖房だんぼうdanbouheating
除湿じょしつjoshitsudehumidify
ドライdoraidehumidify (dry)
自動じどうjidouautomatic

These are the main basic functions of a Japanese air conditioner. Dehumidify (除湿 or ドライ) pulls moisture out of the air, which is why it shows up so often in the rainy season. Most units only cool weakly in that mode, so the room feels less sticky without a full chill. Automatic holds the temperature you set by switching between cooling and heating. You can still move that target with 温度.

Some air conditioners have many more functions and settings. See below some words you may find on these air conditioners or even on heaters:

戻るもどるmodoruback, return
入タイマーいりタイマーiri taimaaon timer

強風きょうふうkyoufuustrong, high
弱風じゃくふうjakufuuweak, low
微風びふうbifuubreeze, very low
静音せいおんseionsilent
運転うんてんuntenoperate, turn on

Some of the settings above sit on the same button and cycle from strong to weak. The fan-speed words usually appear on the screen to show how the unit is running. 運転切換 changes the operating mode. 風量切換 only changes how hard the fan blows.

  • The swing function allows the flap to rotate from top to bottom;
  • The laundry mode adjusts the temperature and humidity to dry your clothes;
  • The fan speed can be set to strong, weak or silent. You click the same button several times to set it the way you want;

Well, I hope these words help you understand how the air conditioning works in Japan. I know that it is still necessary for you to have a basic understanding of temperature and how 冷房 or 暖房 reacts, so you can set it the way you want.
