A marine sauna that makes you feel Japan's early summer.

Beyond everyday life, experience a short trip to Noto's satoyama and satoumi with Gokurakuyu's marine sauna.

Instead of a distant journey, we designed this as an easily accessible Gokurakuyu experience, evoking a familiar, nostalgic sea that blends into daily life, rather than a grand adventure at sea.

Even on days when you can't go to the sea, bring the seaside feeling to the sauna. It's designed as a micro-vacation-like experience that will refresh your mind in a short time.

A special scent inspired by the "Satoyama and Satoumi" of Noto, Ishikawa Prefecture, a World Agricultural Heritage site.

This project expresses the sea of Noto, Ishikawa Prefecture. Noto is a land where the culture of connecting life and nature thrives as "Satoyama and Satoumi." Noto's Satoyama and Satoumi was the first in Japan to be certified as a Globally Important Agricultural Heritage System (GIAHS) on June 11, 2011. The sea is integrated into the landscape not only for tourism but also for daily life – we thought this sense of proximity would be a good match for the marine sauna at the easily accessible Gokurakuyu.

This scent was blended exclusively for Gokurakuyu and RAKU SPA by "KaleidoPath Inc.," which invigorates communities through scent. In collaboration with "MARY JIMENEZ CO.," rooted in Ishikawa Prefecture, we used natural ingredients from Ishikawa to create a blend of natural essential oils that evokes a familiar, nostalgic sea, perfectly matching the image of "beloved, familiar spaces" like Gokurakuyu and RAKU SPA.

Scent Components and Intended Meaning

A bright, clear marine herbal scent reminiscent of Noto's satoyama and satoumi. Grapefruit, evoking a refreshing sunny day on the summer seaside, is complemented by locally grown lemongrass from Ishikawa Prefecture, adding a light, slightly humid, breezy coolness. The scents of laurel, black spruce, and frankincense create depth, like passing from a forest to the sea, expressing the essence of travel that makes you want to breathe deeply. Finally, Japanese perilla from Ishikawa Prefecture adds a familiar greenness found in both gardens and on dining tables.

It's a scent that takes you on a short trip to the sea of Noto, just beyond your everyday life, as if you experienced it in the sauna.

Message from the Representative of KaleidoPath Inc.

Kanta Shimizu, President and Representative Director

I also have roots in Ishikawa Prefecture and often visited my grandparents' home and other places there. I frequently went to the sea and mountains, and those original landscapes are very precious memories for me.

Even when tired from the hustle and bustle of daily life, or when traveling is difficult, I directed this so that people could feel as if they had traveled, even just a little, by visiting their nearby Gokurakuyu.

I also hope this will be an opportunity for people to become interested in Ishikawa, purchase related products, or visit the area.
