Situated in Tokyo’s business district, the latest offering from hotel and resort operator Hoshinoya Resorts, Hoshinoya Tokyo, features a spa and top floor natural hot spring.

Designed by Azuma Architect & Associates and created by large-scale construction specialists Mitsubishi Jisho Sekkei, the 17-storey, 84 room hotel is the city’s first luxury ryokan (traditional Japanese inn), offering traditional Japanese culture combined with high-level hospitality.

Each floor of the hotel replicates a single ryokan, while guest rooms feature cotton futons, low level furniture, deep bathtubs and contemporary styling.

A key feature is the onsen – an inside/outside bath – which is located along a dimly lit corridor on the top floor and is enclosed by walls, providing guests with an unobstructed view of the sky.

The Otemachi Hot Spring's gentle, mineral-rich waters are piped up from 1,500m below street level; they are reported to help the body maintain its temperature and heal cuts, while helping to revitalise and reduce fatigue.

CLAD has previously explored the growing trend of reviving ryokans and onsens, looking at some of the most innovative examples to have emerged in recent years. c
