Embracing Japan’s Beauty
People living in Japan from ancient times perceived ultimate beauty in the changing of the four seasons, and as people shared the excitement of experiencing this beauty, a distinct aesthetic came to be cultivated. Harmonizing this land’s nature, culture, and history, we feel the joy of guests as our own joy. The ideal hotel envisioned by HOTEL THE MITSUI is encapsulated by the brand concept, “Embracing Japan’s Beauty.”
■ HOTEL THE MITSUI HAKONE’s location
Hakone was located on the old Tokaido road that connect Nihonbashi in Tokyo with Kyoto, so historically it was an important post town. For many years, it has been a resort area to beat the heat enjoyed by many people both domestic and foreign, including the birth of Japan's first hotel exclusively for foreigners. It currently is one of Japan’s leading tourism areas where both domestic and foreign travelers gather for the experience of hot springs, the many museums, and the view of Mt. Fuji from Lake Ashi.
In addition, the topography, formed by volcanic eruptions in ancient times, possesses natural diversity. One of the major appeals of Hakone’s natural setting lies in the coexistence of a rough volcanic landscape that still remains and a peaceful resort area atmosphere. The planned site in particular is directly in front of Mt. Sengen. There’s also Jakotsu River that flows at the foot of the mountain, murmuring peacefully, and Chisuji Falls that has a mysterious appearance. It is a prime location for fully experiencing the grandness of nature as its expressions change from season to season.
Hakone’s hot spring come from the activity of the Mt. Hakone volcano, and the Hakone area has hot springs with diverse types of hot springs water. The Kowakudani hot springs, where HOTEL THE MITSUI HOKANE is located, is characterized by an abundance of sodium, and from a source on the site, rich and natural hot springs water that wells up hot will be pumped to all the rooms and thermal springs. Guests can enjoy the experience of a distinctive hot springs in a space fully integrated with nature.

■Sustainability in the Mitsui Fudosan Group
Based on the meaning of its “& mark,” “to generate new value with society through cooperation, coexistence and co-creation, we forge ahead, innovating,” the Mitsui Fudosan Group views the “creation of social value” and the “creation of economic value” as two wheels of a cart. Accordingly, we believe that the creation of social value leads to the creation of economic value, and that this economic value then creates even greater social value.
Moreover, we identified six Group Materiality priority issues when formulating our new management philosophy in April 2024. These Group Materiality priority issues are (1) Contribute to industrial competitiveness, (2) Coexist with the environment, (3) Health and Vitality, (4) Safety and security, (5) Diversity and inclusion, and (6) Compliance and governance. The Mitsui Fudosan Group will work to address each of the materialities through its core business activities and contribute to the promotion of sustainability.
