Why We Created the Sauna
A stone oven, an irori hearth, a rocket stove ...
We had built a number of fire-themed spaces for relaxation, with the exception of a wood-burning stove.
This led us to focus on the environment offered by Daikonjima.
This volcanic island offered underground water at a cool 15°C year-round, ideal for a post-sauna dip.
Moreover, scattered underfoot were basalt rocks, also perfect for a sauna.
Here, where firewood, stone, and water all converged, the Finnish-style private sauna Notta was born.

Commitment to Quality Materials
Sauna stones made of basalt from Daikonjima
Renowned for its quality, hardness, and beauty, Daikonjima basalt was even used in the stone walls of Matsue Castle.
Removing this rare material from Daikonjima is now prohibited, so it may only be used on the island.
Using basalt for our sauna stones offers the following features:
- Superior heat retention and strong far-infrared effects
- Retains heat evenly and generates steam steadily (Löyly in Finnish)
- The steam is gentle and kind to the skin
- Its beautiful black appearance brings elegance to the space

A special time even after the sauna

After your sauna experience, relax in the theater room, a converted attic where silkworms were once kept.
Another highlight is a “sauna meal,” unique to the island.
Enjoy hearty ramen, Chinese dishes, and eel, a specialty of Daikonjima.
We also recommend eel restaurants such as Yamamiyo and Fukamigusa, serving eels kept alive in a tank in Lake Nakaumi.
