Kosekiya Annex

Established around the Tenpo era (1831-1845) under the name "Kosekiya," this historical ryokan has been serving guests seeking therapeutic hot spring stays for an extended period, known as "toji."

Situated alongside the Ginzan River, at the core of the onsen town, this inn exhibits an aura of the Taisho Romance era with its wooden Japanese-style architecture. With the "Romantic Rooms" on the newly renovated fifth floor in 2016 being a highlight, the guest rooms on both the river and mountain sides are spacious, featuring a suite of two adjoining rooms to ensure a comfortable stay.

The bathhouse, filled with Ginzan Onsen's therapeutic waters reputed to benefit conditions like neuralgia and rheumatism, has two indoor baths: "Chika Bath of Warmth" and "Kintaro Bath of Coziness," both luxuriously drawing directly from the source. The baths alternate between men and women depending on the time, enabling guests to experience both during their stay. Those looking for an open-air bath experience can visit the sister inn, "Ginzan-so's" outdoor bath, which is complimentary for overnight guests—a delightful perk. The dinner, a traditional Japanese set meal prepared with local seasonal ingredients, is acclaimed, with varying menus every season, adding to the anticipation of each visit.
