Biography
Keiko Kosaka (born 1953, Kyoto, Japan) is a senior Japanese lithographer whose mature practice has been associated with the Shun'yokai (Shunyo-kai), one of the principal Japanese association-of-artists groupings that has supported lithography and oil painting since the early twentieth century. She trained through the correspondence-education program at Musashino Art University, an unconventional pathway through Japanese fine-art education, and studied under the lithographer Eiji Nagai (永井研治). She is currently based in Tokyo.
Her recent practice, as documented in the 68th CWAJ Print Show 2025, presents lithographs in the medium-large format range — exemplified by 'Holding 24-1' (2024, 57 × 77 cm), a stone or aluminium-plate lithograph published as part of an ongoing 'Holding' series numbered by year and edition position. The 'Holding' title and the year-numbered subtitle (24-1 indicating 2024 first print of the series) suggest a sustained, organized project that returns repeatedly to a single visual or thematic motif.
The Musashino Art University correspondence program has been a notable channel for working artists who entered formal training mid-career or who balance studio practice with other work; the program produces a smaller cohort of graduates than the residential undergraduate degree but has been important for printmakers like Kosaka who came to lithography through a self-directed training pathway. Her study under Eiji Nagai (a senior lithographer associated with Tokyo print activity) places her in a transmission lineage rooted in Japanese postwar lithography.
The Shun'yokai is one of the older Japanese contemporary-art associations, founded in 1922, that has organised annual juried exhibitions across painting, sculpture, and printmaking. Membership for printmakers is sustained through annual exhibition participation and is a credential that signals serious mid- and senior-career practice within the Japanese association system. Kosaka's affiliation places her within the senior cohort of Tokyo-area lithographers active through both the Shun'yokai and the CWAJ.
The visual register of her recent prints, as suggested by the 'Holding' series, is contemplative and abstract or near-abstract: the compositions appear to centre on figures or hands in suspended-action poses, rendered with the softly modelled tonality that lithography permits. The medium-large 57 × 77 cm sheet size is at the upper end of comfortable lithographic plate work — large enough to register as a substantial autonomous image but small enough to remain a hand-pulled print rather than a digital or photo-mechanical reproduction.
Kosaka represents the senior generation of Tokyo-area Japanese lithographers active in the 2020s. Beyond the CWAJ catalogue and Shun'yokai association membership, biographical detail on her exhibition history and earlier production is not currently surfaced through public English-language channels; Japanese-language sources within the Shun'yokai membership directory may extend the documentation.
