Hoshinoya Tokyo brings the hot springs spirit to the heart of the Otemachi business district. The scent of incense wafts through the city’s first luxury ryokan inn, which inhabits an entire 17-story tower; each floor, accessible only by its guests, is designed like a typical Japanese inn. True to tradition, the 84 rooms are minimally furnished with soft cotton futons and soaking tubs; tatami-mat-covered halls lead to a shared lounge with a library, sofas, and dining area for tea and morning miso soup. The top-floor bath is the perfect place to enjoy Tokyo’s seasons through the colors of the sky, along with the winds that drift in.
