To enter the sauna, guests are greeted by a cave-like entrance, which evokes the opening of a turban-like shell. At the tip of the sauna there is a slight oculus that illuminates the interior. ‘Projects that mimic living things are called biomimicry, and this time I was inspired by the irregularity of shellsobserves Taichi Kuma.

The private sauna was open exclusively to hotel guests on 29 September 2022. A full accommodation reservation is required to enjoy the benefits of the sauna experience, which offers towels, hats, detox water and whip rental, among others. other things.

Bringing on Instagram, chief architect Taichi Kuma further describes the interior design of the “SAZAE” sauna as acave-like space cut off from the outside world by a thick wall […] The only light that enters comes from the eye. To feel the light, I created countless folds and ripples with laminated plywood.‘By sculpting the surfaces with undulating movements, an engaging play of shadows invades the room, helping guests to further relax in the sauna experience at the HEALTHY MANE glamping facility without succumbing to any distraction.

To get that final spiral and pleated shape, the squad at Kengo Kuma & Associates, together TTNE and structural engineers created a series of digital simulations. ‘Normally, a space with such a high ceiling would not be suitable for a sauna. This is achieved by performing forced ventilation with intake from above and exhaust from below. By checking the model with 3D CAD and programming software, we were able to detail everything from shape to paneling and iterate heat simulationswrites the architect.

Once the final model was approved, the team proceeded to build the “SAZAE” sauna using approximately 5,000 pieces of CNC-cut plywood assembled on site as a puzzle, resulting in the intricately pleated and textured volume that changes shape from different angles.
