Why it’s popular
The 'seven springs' hidden deep at the foot of Mount Nyūtō in Akita (Tsurunoyu, Taenoyu, Ganiba and others), cut off by heavy snow in winter, are a mecca of Japan's 'hitō' (secret hot spring) culture. The most famous, Tsurunoyu, with its thatched mixed open-air bath, is almost impossible to book all year — many have heard of it, but few actually go.

Culture & customs
Background
The name 'Nyūtō' (nipple) comes from the shape of Mount Nyūtō; Tsurunoyu is said to have opened in 1688 and was the 'official bath' of the lords of the Akita domain; the 'Yu-meguri-chō' (a stamp book for touring all seven springs) is a coming-of-age for hot-spring lovers. Thatched roofs, irori hearths and yam hotpot make up a winter poem of a Tōhoku mountain village.
Local customs
- Always rinse off before bathing
- towels must not go into the water (you can put yours on your head)
- in mixed open-air baths follow each inn's rules (women may wrap themselves in a bath towel
- don't stare at others)
- speak softly inside the ryokan.
Religion & beliefs
No particular religion. But 'tōji' (hot-spring healing) has an almost devotional tradition in Japan, and gratitude to the springs is a shared local value.

Rules that apply here
If you have tattoos, check the rules before using a hot spring
- Before you go, email the facility to ask about its rules
- Small to medium tattoos can be covered with skin-coloured patches (some onsen sell them)
- Choose a tattoo-friendly onsen, or book a private bath (kashikiri-buro) in advance
- Ignoring 'no tattoos' signs and getting in anyway
Most onsen do not allow guests with tattoos to bathe, but rules vary by facility and are often more relaxed for foreign visitors.

Wash your body thoroughly before getting into a hot spring
- Before getting in, sit on the small stool in the washing area and wash your whole body with the shower or a bucket, leaving no soap
- Leave your small towel at the edge of the bath or fold it on your head
- Getting into the bath without rinsing first
- Dipping your towel in the bath water
- Leaving a used towel in the washing area
Not illegal, but other guests and the staff will see it as very rude. Most onsen require you to be fully naked in the bathing area.
