['FAS' Fermented Aging Care Brand × HOTEL THE MITSUI KYOTO] Limited-Time 'Precious Escape' SPA and Lunch Plan Announced

FAS, a fermented aging care*¹ brand developed by Shiroku Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Yuta Iizuka), announces a collaboration plan titled 'Precious Escape' at 'HOTEL THE MITSUI KYOTO' (Location: 284 Nijoaburano-koji-cho, Nakagyo-ku, Kyoto; General Manager: Yuji Kaseda), located in front of the World Heritage Nijo Castle in central Kyoto. The plan, offering a SPA treatment and a special lunch course, will be available for a limited time from Monday, May 11, 2026, to Sunday, September 13, 2026.

This special collaboration was realized through a deep resonance between FAS's craftsmanship—which sublimates the ancient Japanese technique of 'fermentation' through modern 'science' to approach the skin in diverse ways—and the spirit of 'Inheritance and Rebirth' cherished by HOTEL THE MITSUI KYOTO, creating new value by adding modern sensibility to inherited traditions.

This day-retreat plan allows guests to enjoy a SPA treatment alongside a special lunch course created around the theme of fermentation. Guests can indulge in a spa experience luxuriously utilizing FAS fermented skincare products at the 'Thermal Spring SPA,' which earned a 5-star rating in the SPA category of the Forbes Travel Guide 2026. Additionally, guests will enjoy a special lunch course incorporating Kyoto-produced 'black rice' and 'multifloral honey,' which are used as ingredients in FAS skincare products.

Through this plan woven by two brands breathing life into Kyoto, elegantly satisfying both mind and body, please spend a special moment away from the hustle and bustle of daily life to relax to your heart's content.
