Japanese for onsen & bathhouses

What the signs mean, what the etiquette is, and the handful of phrases that make a first onsen visit relaxed rather than nerve-racking.

Onsen etiquette is strict but simple, and almost all of it follows from one rule: you wash before you get in, and the bath itself is only for soaking.

Signs to read first

onsen
hot spring
sentō
public bathhouse
otoko / onna
men / women - check before the curtain
yu
hot water - often the only sign on the curtain
rotenburo
outdoor bath
kashikiri-buro
private bath you reserve
Why it works

The 男/女 curtains are sometimes swapped between morning and evening, so check every time rather than relying on where you went last night. 湯 is the character to burn into memory - it marks the baths everywhere.

Etiquette

kakeyu
rinsing yourself before entering
karada o arau
to wash your body (before the bath)
taoru
towel - keep it out of the water
irezumi / tatū
tattoo
datsuijo
changing room
Why it works

Two things catch visitors out. You wash thoroughly at the seated showers first - the bath is for soaking in clean. And many onsen still refuse entry to guests with visible tattoos; search for 入れ墨OK (irezumi OK) places or book a 貸切風呂 if that affects you.

Useful phrases

hajimete desu.
It’s my first time.
taoru o kariraremasu ka.
Can I rent a towel?
atsui desu.
It’s hot.
kimochi ii.
That feels good.
Why it works

初めてです is quietly the most useful sentence here - staff will happily walk a first-timer through the routine, and saying it removes any worry about getting the etiquette wrong.
