Introduction
The sauna as a tea room, the rest area as an engawa
OOO's concept is the “communication sauna”. The sauna room is seen as a tea room, the cold-bath space as a garden and the rest area as an engawa veranda. Every sauna room has tatami.
Finland has the phrase “sauna diplomacy”, and the tea room was a place where people became equal regardless of rank. This space grew from what the two have in common.
01 · Full Moon room
The largest room
The Full Moon room is 36.2 m² and takes 1–8 people.
In the large sauna you sit around the stove as if around a hearth — an arrangement for talking in a group.

02 · First Quarter room
A room for 1–4
The First Quarter room is 23.3 m² and takes 1–4 people.

03 · Crescent Moon room
A small room for 1–2
The Crescent Moon room is 15.0 m² and takes 1–2 people.
In the smaller rooms you sit side by side facing the stove — an arrangement for time with someone close.


What is a chashitsu?
A small room for making tea and receiving guests. Some have a low entrance so that everyone bows their head to enter.
SAUNA OOO treats its sauna rooms as tea rooms.
