Yamada Ryokan Bathroom

About the Yamada Ryokan Bathroom

The Yamada Ryokan Bathroom (山田旅館浴室, Yamada Ryokan Yokushitsu) is a two-storey timber bathhouse at Otari Onsen in Otari Village, Nagano Prefecture, rebuilt in its present form in 1926 and registered as a Registered Tangible Cultural Property on October 12, 2001, under number 20-0094.

Despite the name, the Yamada Ryokan Bathroom is a building rather than a room: a gabled Kirizuma-zukuri structure with a sheet-metal roof and a building area of 96 square meters. The inn calls it the Moto-yu bath hall, places it at the center of the house, and still fills its tub every day from the original Moto-yu spring.

Why It Was Registered: From Open-Air Shelter to Western-Style Bath Hall

The Yamada Ryokan Bathroom was registered for its contribution to the historic landscape. According to the Agency for Cultural Affairs, it is joined to the west gable of the row building, the nagaya, and runs west toward the New Building.

The Agency also records how it began. At first it was nothing more than a simple shelter roofed over an open-air bath. In 1926 it was rebuilt and the bathing room inside was finished in a Western style. A shed over a hot pool became a two-storey bathhouse built to receive guests who came to take the cure.

Outside, the two-storey gabled building stands taller than the nagaya to its east. The Agency credits the line of nagaya, bathhouse and New Building with giving the inn the look of a spa-town street. The Yamada Ryokan Bathroom sits between the low row building and the three-storey guest wing, stepping the line up in height.

What to Look For: A Two-Meter Cascade and Keyaki Double Doors

According to the inn, the tub of the Yamada Ryokan Bathroom has been in use, unchanged, for more than a century and has a design that recalls the romantic taste of the Taisho era. Spring water drops about 2 meters in a small cascade, so bathers can stand under it as an utaseyu, a falling-water bath. The inn also offers lying-down bathing, floating and steam inhalation.

The entrance has Kannon-biraki double doors of Keyaki (Japanese zelkova), which the inn says survive from the original building. Before you step in, take a moment to look at the grain of those doors.

The water comes from the inn's own Moto-yu spring and goes into the tub without added water or heating. It is a sodium bicarbonate spring.

In 2021 the Yamada Ryokan Bathroom was renovated by Tokutake, a master carpenter from Otari. The changing room became a tatami space under a coffered Gō-tenjō ceiling, and a multipurpose room with large exposed beams was created upstairs, which the inn offers for remote work.

Visiting the Yamada Ryokan Bathroom

Only overnight guests and day bathers can enter the Yamada Ryokan Bathroom. Overnight guests can use it at any hour except during cleaning, every day of the year. Day bathers can use the Moto-yu bath hall all year from 11:00 a.m. to 3:00 p.m., for 700 yen for adults and 400 yen for children, with reception closing at 2:30 p.m. When the outdoor bath closes for winter, the Yamada Ryokan Bathroom remains open to day visitors. No visits without bathing are offered.

The bath is small, and the inn asks guests to avoid busy times so that everyone can soak in peace. Do not take photos while others are bathing, and ask the staff if you want to photograph the room. From within the grounds you can see the building between the nagaya and the New Building (checked October 9, 2026).
