Mitsui Fudosan to open a 126-room onsen hotel on its family's former Hakone estate
Every one of the 126 rooms will have its own hot-spring bath — the second hotel under Mitsui Fudosan's HOTEL THE MITSUI brand bets on space and privacy, not room count, at a former family villa estate in Hakone.
Mitsui Fudosan said it will open HOTEL THE MITSUI HAKONE on 15 December, a 126-room hotel in Kowakudani, Hakone, where every room will come with its own private natural hot-spring bath. Reservations open on 15 July, two days after the announcement.
The hotel sits on roughly 135,500 square metres of land in Kowakudani which, according to Mitsui Fudosan, was once home to a cluster of the Mitsui family's own villas. Divided across 126 rooms, that works out to more than 1,000 square metres of grounds per room — a low-density ratio that signals space and privacy, rather than room count, is the product here. Interiors are by the international design firm Yabu Pushelberg, the company said.
HOTEL THE MITSUI HAKONE is the second hotel under the HOTEL THE MITSUI brand, Mitsui Fudosan said, following HOTEL THE MITSUI KYOTO. It will be run by Mitsui Fudosan Resort Management, the group company that also operates Halekulani Okinawa under its own separate brand — evidence that Mitsui Fudosan is assembling a small portfolio of distinct luxury-hotel labels rather than one chain.
For a developer whose core business is dense Tokyo towers and shopping centres, the logic here runs the other way: convert a single legacy landholding into a small-format, high-privacy hotel, and let the address and the generous room-to-land ratio carry the story ahead of any room rate, which Mitsui Fudosan has not yet disclosed. The December opening also lands just ahead of Japan's peak New Year onsen-travel season, in a Hakone market that already gives affluent domestic and inbound travellers plenty of choice. Whether the bet pays off will show first in how quickly the 15 July booking window fills.
