Dokuritsu Shashin Kenkyūkai

Dokuritsu Shashin Kenkyūkai (独立寫眞研究會; modern Japanese: 独立写真研究会; lit. "Independent Photography Research Association") was a photography circle based in Nagoya, Japan, founded in October 1931 by the photographers Kentarō Shimizu, Hachirō Tomita, and Mitsuya Okonogi.^[1]

The group published a printed, pamphlet-format bulletin titled Dokuritsu (『独立』) in four issues, from A.1 (November 1931) through B.2 (April 1932).^[2] In histories of Nagoya modern photography, Dokuritsu is discussed as part of the interwar Shinkō shashin (新興写真) milieu.^[1]

Among its members was the photographer-poet Kansuke Yamamoto, who began making highly accomplished and sharply critical photo-collages during this period.^[3] His 1932 gelatin silver print collage Development of a Man's Thought…Mist and Bed Room (或る人間の思想の発展…靄と寝室と) is in the collection of the Nagoya City Art Museum.^[4]

The group's name appears in contemporary materials in prewar orthography as 独立寫眞研究會.^[5] In modern Japanese writing it is generally rendered in shinjitai as 独立写真研究会.^[6]

In English-language scholarship on Kansuke Yamamoto, the name has been romanized as Dokuritsu Shashin Kenkyūkai and translated as the “Independent Photography Research Association”.^[7] Macrons are often omitted in English contexts (Dokuritsu Shashin Kenkyukai).^[8]

The association's bulletin was titled 『独立』 (Dokuritsu, “Independent”).^[5]

The Nagoya City Art Museum notes that a distinctive feature of Nagoya's photographic culture was the production of self-published media—group journals, newsletters, and photo books—used to communicate photographers’ intentions and ideas alongside exhibitions.^[9]

Within the annual report's survey framework, the interwar period is presented under the heading “Modern cityscapes: the rise and experimentation of 新興写真 (Shinkō shashin)”, and the object list includes the numbered bulletin 独立 (Dokuritsu) issued by Dokuritsu Shashin Kenkyūkai.^[9] The museum describes Dokuritsu as a printed, pamphlet-format publication (a folded booklet; two sheets, eight pages) and records that it ran for four issues, from A.1 (November 1931) to B.2 (April 1932).^[10]

The same section also lists Kansuke Yamamoto’s 1932 gelatin silver print collage Development of a Man's Thought…Mist and Bed Room.^[10] A later chronology records that a photocollage by Yamamoto was reproduced in issue B-2 (1932).^[11]

The 独立寫眞研究會 (Dokuritsu Shashin Kenkyūkai) was formed in Nagoya in October 1931. Later accounts describe the group as a new generation of local photographers seeking alternatives to pictorialist “art photography” and the gum-printing process; Kansuke Yamamoto joined as a founding member at age seventeen. The group was organized by the Nagoya photographer Mitsuya Okonogi, and its membership included Kentarō Shimizu and Hachirō Tomita, as well as founding members Masaya Kaifu and Shōjirō Mikuni (both formerly associated with the Aiyū Photography Club).^[12]

The group's principal documented activity was the publication of its numbered bulletin 独立 (Dokuritsu). A Nagoya City Art Museum annual report lists Dokuritsu as the group's organ and records that it ran from November 1931 to April 1932, ending after four issues numbered A.1–B.2 (tabloid format).^[13]

In later scholarship, the Dokuritsu bulletin has been discussed as an important forum for debate and exchange within Nagoya's emerging Shinkō shashin (New Photography) milieu.^[12] The final issue (B.2) also reproduced Yamamoto's photocollage Aru ningen no shisō no hatten—moya to shinshitsu (The Developing Thought of a Human… Mist and Bedroom and) (dated 5 April 1932), indicating the magazine's role as an early print venue for montage-based experimentation.^[11]

Published accounts note that surviving documentation on the 独立寫眞研究會 (Dokuritsu Shashin Kenkyūkai) is limited, but identify Kansuke Yamamoto as a founding member of the group, which was organized by the Nagoya-based photographer Mitsuya Okonogi.^[14] The same account names Kentarō Shimizu and Hachirō Tomita as prominent members, and identifies Masaya Kaifu and Shōjirō Mikuni as additional founding members (both also associated with the earlier Aiyū Shashin Kurabu).^[14]

• Kansuke Yamamoto (山本 悍右) — founding member.^[14][15]
• Mitsuya Okonogi (小此木光也) — organizer; named as a member in Yamamoto's chronology.^[14][15]
• Masaya Kaifu (海部誠也) — founding member; also named as a member in Yamamoto's chronology.^[14][15]
• Shōjirō Mikuni (三國庄次郎) — founding member; also named as a member in Yamamoto's chronology.^[14][15]

• Kentarō Shimizu — described as a prominent member.^[14]
• Hachirō Tomita — described as a prominent member.^[14]

The Dokuritsu Shashin Kenkyūkai issued a numbered bulletin titled Dokuritsu (独立). A Nagoya City Art Museum annual report describes the bulletin as a printed, self-produced folded booklet (two sheets, eight pages), and notes that the run is confirmed in four issues from A.1 to B.2 (November 1931–April 1932), after which it ceased publication.^[16]

In the inaugural issue A-1 (5 November 1931), the group's statement of purpose defined the bulletin as a vehicle for affirming the creator's freedom in production and for rejecting constraints imposed by collective research bodies, emphasizing instead the value of individual personality: 「作家の自由製作態度を肯定し、研究会団体、研究者共同組織による束縛を排除し、個人の個性を尊重する」.^[11]

Documented contributions by Kansuke Yamamoto include a short text titled Dai to shudai (題と主題; “Title and subject”) in issue B-1 (5 January 1932), and the reproduction of a photocollage from his early series Aru ningen no shisō no hatten… moya to shinshitsu to (ある人間の思想の発展…靄と寝室と) in issue B-2 (5 April 1932).^[11] The Nagoya City Art Museum annual report also records this 1932 collage (g.s.p., collage) in the museum's collection, underscoring how the group's small-scale print forum overlapped with early montage-based experimentation in Nagoya.^[16]

Later accounts emphasize that the group's bulletin 独立 (Dokuritsu) did more than circulate essays: it also reproduced members’ works, making the printed page a practical site for experimentation and exchange in Nagoya's early-1930s photographic modernism.^[17][11]

The bulletin provided an early venue in Nagoya for montage-based practice. According to Yamamoto's chronology in the 2001 Tokyo Station Gallery catalogue, a photocollage by Kansuke Yamamoto was reproduced in issue B-2 (5 April 1932), alongside his contribution “題と主題（二）” (Dai to shudai [“Title and subject”], part 2).^[11] In broader discussion of Yamamoto's 1930s work, Eiko Aoki also treats collage and montage as central to how his photographic modernism has been framed for international audiences.^[18]

A key surviving example associated with the group's early print culture is Yamamoto's Development of a Man’s Thought…Mist and Bed Room (或る人間の思想の発展…靄と寝室と), dated 1932. The Nagoya City Art Museum records the work as a gelatin silver print with collage on paper (28.1 × 20.7 cm).^[19] The museum's annual report likewise lists the piece together with surviving issues of 独立 (A.1–B.2), underscoring how making pictures, writing about them, and circulating them in small printed formats operated as a single, locally sustained workflow in Nagoya's prewar photography networks.^[17]

Later museum catalogues and scholarship treat the short-lived 独立寫眞研究會 and its bulletin 独立 (Dokuritsu) as a key piece of documentary evidence for interwar photographic modernism in Nagoya. In the catalogue for Tokyo Station Gallery's retrospective on Kansuke Yamamoto, the bulletin is described as a self-produced forum for debate and exchange and is characterized as an essential catalyst for the development of Shinkō shashin (New Photography) in Nagoya.^[12]

Institutional collection documentation likewise preserves the group's print activity within Nagoya's photographic history. The Nagoya City Art Museum’s annual report lists the bulletin 独立 as a printed, folded booklet, noting its four-issue run (A.1–B.2) from November 1931 to April 1932, and records surviving copies in private collections.^[20] In the same report, Yamamoto's 1932 gelatin-silver print and collage Development of a Man’s Thought…Mist and Bed Room is catalogued as a museum holding, underscoring how the group's bulletin culture intersected with early experiments in montage-based practice in Nagoya.^[20][21]

Because it is repeatedly invoked in curatorial and scholarly narratives as both a primary source and a material trace of Nagoya's self-organized photographic networks, Dokuritsu has remained a durable reference point for accounts of the city's Shinkō shashin milieu and its early crossings with photomontage and Surrealist-inflected techniques.^[12]
