Former Warehouse of the Maruyon Textile Company (Dolce Warehouse)

A Cotton Warehouse That Turned Out to Sound Good

The Former Marushi Textile Company Warehouse, known today as Dolce Souko (旧丸四織物合名会社倉庫（ドルチェ倉庫）, Kyū Marushi Orimono Gōmei Gaisha Sōko), is a wooden storehouse in the Fukude district of Iwata City, Shizuoka Prefecture, built in the early Shōwa period between 1926 and 1945 and entered on Japan's national register of Tangible Cultural Properties on 21 June 2013. It has a building footprint of 129 square metres, and since 1997 it has worked as a small acoustic concert hall.

The conversion was not a developer's project. Terada Akiko, the founding representative of the local music society Andante, remodelled the warehouse on her own family's property and opened it in April 1997. According to the Shizuoka Shimbun, a musician from the NHK Symphony Orchestra who played the opening concert remarked that the warehouse had a dolce sound, and the name stuck. Dolce is the musical direction meaning sweet or soft.

The registration in 2013 covered the warehouse together with the neighbouring Terada House Main Building, the company's office and residence, a Japanese house with a Western-style wing attached.

What the Building Is

It stands at the southeast corner of the site, and it was built to hold thread and cloth. The roof is gabled and laid in pantiles (sangawara). On the north face a lean-to (geya) shelters the entrance at the centre. The outer walls are clad in horizontal weatherboarding (shitamiita-bari). Two double-leaf windows open on each of the east, south and west faces, and a clerestory window sits high in each gable end.

Then comes the decision that made the building what it is now.

The warehouse originally had a floor across the attic level, giving it two storeys of storage. That floor was taken out, and the roof structure above is now open to the room: a nijūbari wagoya, the Japanese double-beam truss, with a lower and an upper tie beam carrying the rafters. What was a low, stacked storage space became a single tall volume of exposed timber. Removing a floor is normally a loss for a heritage building. Here it revealed the carpentry and produced the acoustics at the same time.

The venue's own guidance is honest about the consequences. The hall is a prewar timber building with no acoustic treatment and no soundproofing. Amplified instruments and large drums are not suitable. Unamplified voices carry perfectly well, and audiences describe hearing the performer's breathing.

Why Fukude Had Warehouses Like This

Fukude, pronounced fukude and not fukuda, is the coastal district of Iwata City that faces the Enshū Sea, and it is the reason a warehouse of this size existed here at all.

The local textile tradition is usually traced to 1831, when a village headman named Terada Hikozaemon brought the technique of unsai-ori, a heavy cotton weave, back from a journey to the Yamato region and introduced it as a sideline for farming and fishing households. Corduroy production followed in the mid-Meiji period, driven by demand for geta thong material, and Fukude grew into a specialist centre. The two fabrics the district is known for are betchin, velveteen, and kōruten, the local name for corduroy. Fukude remains the only domestic production area for them.

The warehouse also carries a wartime trace. It served as a storage facility for cotton held by the state at the end of the war, and a Japanese government notice board from that period still hangs at the entrance, citing the penalty under the Potsdam Ordinance. Employee shoe lockers survive as well. Visitors tend to walk past both of these on the way to a concert without registering what they are.

Visiting: This Is a Venue, Not a Museum

There is no ticket window and no standing opening schedule. Dolce Souko is a rental hall, managed by the founder's family, and the practical way to see the interior is to attend one of the concerts held there or to book the space yourself.

The published rates run at 7,000 yen for a daytime session of 9:00 to 16:30 and the same for an evening session of 17:00 to 21:00, or 14,000 yen for a full day, with air conditioning adding 1,000 yen per session. The hall keeps a piano, around seventy chairs, a staging platform, three air-conditioning units and an accessible toilet. There is also a Yamaha reed organ made in 1942. Bookings and enquiries go through the venue's own website, or by email at dolce.souko@gmail.com.

Free parking on the site holds up to twenty-seven cars. The venue has announced that overflow parking outside the grounds becomes chargeable from 1 June 2026, so a group event needs planning.

If you are in the area for the textiles rather than the music, Corduroy House in Fukude Nakajima, run by the Tenryūsha textile cooperative, displays and sells roughly six hundred kinds of locally woven fabric. It makes a natural pairing with the warehouse: the cloth that used to be stored here is still being made a short drive away.

One note on the address. The national database records the site as Fukude, Aza Murasaki-higashi 4447-2 and others, while the venue publishes its address as Fukude 6085-15. The discrepancy reflects land-parcel numbering against a postal address, and the venue's version is the one to use for navigation.
