Souan Kosumosu vs Kaze no Mori: Shared Baths or a Private Onsen in Every Room?

Checked: September 27, 2026 These two inns suit different kinds of Yufuin stay. Souan Kosumosu sits near town’s walking sights and lets main-building guests use shared private-use baths. Kaze no Mori is quieter and more self-contained: all ten rooms are detached, and every room has its own indoor and outdoor bath.

Kaze no Mori makes the room choice simpler

Kaze no Mori has six room categories, but the basic bathing setup is consistent. Every detached room includes a private indoor bath and an open-air bath supplied by the inn’s own spring. The official room page lists the spring at pH 9.0 and describes it as a sodium bicarbonate spring; its bath information says the room tubs are free-flowing. The shared public bath has set opening hours, so rely on the room facilities if bathing late or early is important.

The categories mainly change floor area and layout. The Standard room is 23 square metres and suited to one or two guests; the Royal Suite is 104 square metres, has a separate dining area and can accommodate a larger group. For two people, it may be enough to choose by room size and sleeping arrangement rather than assume a higher category is needed to get the private bath.

Souan Kosumosu needs a closer look at the room type. Its detached rooms all have a free-flowing outdoor spring bath available 24 hours. Main-building rooms vary: one category has an indoor bath, while other categories list a shower. Main-building guests can use the public baths and two first-come private-use bath sets during opening hours.

What do you want the extra room cost to buy?

At Souan Kosumosu, the main building can be the practical choice if you do not need a private tub in your room. The two shared private-use sets each include an indoor and an outdoor bath; they are free to use, but cannot be reserved. Opening hours are 3–11 p.m. and 6:30–10 a.m. You may have to wait if another party is using them.

Booking a detached room at Souan removes that uncertainty and adds a private outdoor bath that can be used at any hour. At Kaze no Mori, the same basic private-bath setup comes with every room. If you expect to soak several times a day—or prefer not to plan around shared facilities—Kaze no Mori is more straightforward. If one scheduled private soak is enough, Souan’s main-building option leaves more of the budget for the location or meal plan.

Town on foot or a reserved pickup?

Souan Kosumosu is around a 15-minute walk from Yufuin Station and close to Lake Kinrinko and Yuno Tsubo Street. Guests can call for pickup after they reach the station; it cannot be booked in advance. That makes it easier to build a day around town without arranging taxis between the inn and central sights.

Kaze no Mori is about a 20-minute walk from the station. The inn’s complimentary pickup is limited to five scheduled afternoon arrivals, runs only with a full advance reservation and must be booked by 3 p.m. the previous day. Seats are limited, and an unreserved shuttle does not run. If your train misses those slots, arrange a taxi or be ready for the walk.

The difference matters more in autumn, when the walk back after a day outdoors can feel longer in cold rain. The private baths are useful either way; the transport plan is what changes. The Yufuin access guide covers the longer trip into town, while the Yufuin autumn ryokan guide compares other bases.

Autumn is scenery around the stay, not a room guarantee

Oita’s tourism guide gives Mount Yufu a usual foliage window from late October through mid-November. Yufuin’s central sights are easy to reach from Souan Kosumosu; Kaze no Mori’s quieter setting puts more of the stay on the grounds. Neither inn can guarantee peak color on a particular date or from a specific room.

If you expect to spend most of the day walking around Kinrinko and the shopping street, Souan’s location cuts down on logistics. Kaze no Mori makes more sense when the room itself is part of the plan: both tubs are private, and you can return to your cottage for another soak without checking a shared-bath timetable.

A quick way to compare the actual booking

Use the same date, guest count, meal plan and cancellation terms. At Souan, compare a main-building room against the detached category you would genuinely book; at Kaze no Mori, match the room size and layout to your group. An entry-level room at Kaze no Mori already includes the two private baths, while a Souan main-building room does not necessarily have a bath in the room.

Choose Souan Kosumosu if you want to stay close to town and are comfortable deciding between shared facilities and a detached-room upgrade. Kaze no Mori is the easier fit when a private indoor and outdoor bath in every room is the starting requirement, and you can work around its scheduled pickup.
