The Second “HOTEL THE MITSUI” After Kyoto

Opened in 2020, HOTEL THE MITSUI KYOTO achieved the rare double of Forbes Travel Guide Five-Star and Michelin Three-Key accolades.
Carrying on that legacy, the new Hakone property embraces the brand concept “Embracing Japan’s Beauty,” offering true hospitality woven from traditional culture, nature, and architectural elegance.
