Born and raised in Morioka, Japan, Soko Yoshida is a violinist and violist specializing in historically informed performance. While studying at Tokyo University of the Arts, where she graduated with honors, she was introduced to the baroque violin by Natsumi Wakamatsu. This encounter sparked a deep interest in early music and led her to devote herself to historical performance. After graduation, she became active in Tokyo's early music scene, collaborating with ensembles such as Bach Collegium Japan, Orchestra Libera Classica, and Les Boréades.

In 2018, she moved to Switzerland to study baroque violin with Leila Schayegh at the Schola Cantorum Basiliensis, where she completed two further Master's degrees. Additionally, she studied medieval fiddle with Baptiste Romain and historical improvisation with Nicola Cumer and Dirk Börner. From 2019 to 2021, she was a scholarship recipient of the Japan Agency for Cultural Affairs.

In 2022, she won the International Competition for Baroque Violin “José Herrando” (Spain). She is co-founder of the Basel-based early music ensemble El Gabinete de Música, which presents the concert series Das Musikzimmer in Basel and performs throughout Europe. She has collaborated with ensembles such as Il Pomo d'Oro, Ensemble Locatelli, Barokkbandið Brák, Cardinal Complex, La Cetra Barockorchester, Capriccio Barockorchester, and La Centifolia.

Her performances have been featured in prestigious concert series and festivals, including Abendmusiken Basel, Freunde Alter Musik Basel, Festtage Alte Musik (CH), Clásicos en Verano, Festival Música Barroca (ES), Schleswig-Holstein Festival, Kulturfreunde Bayreuth (DE), Festival de Saintes (FR), Palazzo Marino in Musica, Monteverdi Festival Cremona (IT), and Festival Internacional de Música Renacentista y Barroca Americana “Misiones de Chiquitos” (BO).
