Overview
Hoshino Resorts KAI Hakone is distinguished by its rare format in Hakone, featuring only 34 rooms. This unique aspect alters the flow, silence, and pace of the stay.
The property also includes 2 Hakone Gokochi Suites, each exceeding 110 square metres. For families, this is certainly a point worth considering.
Another notable feature is the 14-sided tower, which gives the ryokan a less conventional silhouette compared to the usual folklore of Hakone.
At Hoshino Resorts, the establishment plays with this contrast. On one hand, there is a codified thermal setting, complete with hot spring ryokan, sauna, jacuzzi, and swimming pool. On the other hand, the limited capacity prevents the feeling of a bustling resort.
Dining here highlights two signature dishes: the classic boiled beef and vegetables in broth, a staple of Hakone, and a seafood shabu-shabu served in sea urchin broth.
In this context, Hakone is better appreciated as a serene edition rather than a grand spectacle.
History & Heritage
Opened in 2012, KAI Hakone embodies the contemporary interpretation of the ryokan concept championed by Hoshino Resorts. The establishment merges thermal hospitality with a keen attention to the landscape.
Since its inception, the hotel has welcomed guests around two key features of Hakone: the outdoor public bath and rooms that overlook Mount Yusaka and the Sukumo River.
Its heritage is also reflected in the decor. The ryokan is adorned with Yosegi-zaiku, a traditional marquetry from Hakone, with geometric patterns that extend the region's artisanal history.
This presence of local craftsmanship is far from incidental. It supports an approach focused on experiencing the traditions of Hakone, within a setting designed to connect stay, bathing, and culture.
Thus, the history of KAI Hakone is relatively recent but already distinctly defined. It is a house operated by Hoshino Resorts since 2012, attentive to the identity of the locale rather than merely its effects.
A new chapter will begin with its reopening scheduled for 1st August 2025. This continuity illuminates the purpose of the establishment: to embody a certain vision of Hakone over time.
