Hakone Kowakien Motoyu Mori‑no‑Yu

Hakone Kowakien Motoyu Mori‑no‑Yu is a day‑use hot spring facility where guests can enjoy authentic onsen bathing while fully immersed in the rich natural surroundings of Hakone. The spacious open‑air bath offers sweeping views of the Hakone outer rim mountains, creating a relaxing sensation of bathing in harmony with nature. Even in the large indoor bath, expansive windows allow guests to enjoy the scenic landscape.
The facility also features eight private reservable hot spring baths (100% natural hot spring water), ideal for families and couples who wish to enjoy the onsen experience in complete privacy.
In March 2025, the lobby and relaxation areas were renovated, introducing a calm, wood‑accented lobby and newly designed rest spaces where guests can unwind after bathing. As a comfortable and authentic hot spring spot, Mori‑no‑Yu continues to be popular with travelers visiting Hakone.
