Four waters,
one order.

The hall runs on a fixed sequence. Follow it and the effect compounds; skip it and you are simply having a warm bath.

The sequence

In this order.

Tomo sets the circuit and checks the water four times a day. He will move you along at twelve minutes in the hot tub whether or not you are ready, and he is right to.

41°Cedar soaking tub — twelve minutes, no longer.
SteamHinoki steam room until the first proper sweat arrives.
14°Cold plunge — ninety seconds, breathing through the nose.
RestTwenty minutes horizontal on the stone deck. This is the part that works.

Repeat the cycle up to three times. Bathing is included with every treatment and every day pass.

The waters

Where each one comes from.

The cedar tub

Hinoki, replaced every four years, filled from the borehole beneath the garden and held at 41°. Twelve minutes is not arbitrary — it is where most bodies stop benefiting.

The steam room

Stone-lined, 46° at ninety percent humidity, with hinoki oil dropped on the coals at the half hour. The one place in the house with a scent, and it is the wood itself.

The plunge

Held at 14° year round, refreshed continuously. Ninety seconds is the target; the first three visits it will feel impossible and then one day it will not.

The stone deck

Warmed from below, open to the garden, and silent. If you only have an hour, spend forty minutes of it here.

Etiquette

How the hall is used.

Most of this is ordinary onsen practice. If you have never bathed this way, Tomo will walk you through it once on arrival and then leave you alone.

Wash before you enter

Properly, seated, at the wall stations. The baths are for soaking, not for cleaning.

No swimwear

The main halls are separated by gender and bathed unclothed, as is normal here. The garden bath is mixed and robed.

No talking

Not whispering, not quietly. Anything that needs saying can be said in the garden room.

Tattoos are welcome

Unconditionally, and without a cover patch. We are aware this is unusual in Japan; we made the decision in 2009 and have never revisited it.

Hydrate between cycles

Barley tea and cold water sit at both ends of the hall. Two cups per cycle, at least.

Hours

Before you get in

Worth knowing.

No. Roughly a quarter of guests never use it and the circuit still works. If you would like to build up to it, start by standing in it to the knee for thirty seconds and go from there.

Tell Tomo before you enter. Contrast bathing puts real load on the cardiovascular system, and he will design a warm-only sequence that skips the plunge and shortens the hot tub.

Yes — the day pass at ¥6,800 covers the hall, the classes and the rest rooms for as long as we are open.

Nothing. Robe, towels, cotton wear, comb, and unscented amenities are all provided. Leave your own products at home — the fragrance rule applies in the changing rooms too.

Only during the Saturday family hour, robed, in the garden bath. The main halls are adults only at all times.

The water is open from seven.

A day pass includes the whole hall, the timetable, the rest rooms and the tea. Nothing else needs deciding in advance.
