With her superlative technique, sensitivity of touch and profound understanding of the music she plays, Yu has become one of the world’s most noted young pianists.
Yu Kosuge has been giving recitals and performing with orchestras since early childhood. At the age of nine she made her debut with the Tokyo New City Orchestra.  In 1993, she moved to Europe to pursue studies with Karl-Heinz Kammerling in Hannover and Salzburg and in recent years has received great support and inspiration from Andras Schiff.
Yu Kosuge appears at the most important venues in Berlin, Hamburg, Koln, Munich, Vienna, Salzburg, Paris, Brussels, Amsterdam, Zurich, Moscow, St. Petersburg, Tokyo, Washington and New York. Her Carnegie Hall debut recital met with outstanding success with critics praising her “acutely poetic sensibility…wit, drama, and effulgent lyricism.”
Recent highlights include performing at the Salzburg Festival with Philippe Herreweghe and Camerata Salzburg, performances in La Roque d’Antheron with Jacek Kaspszyk/Sinfonia Varsovia, the Japanese premiere of Tan Dun’s Piano Concerto ‘Fire’ with the NHK Symphony Orchestra under the baton of the composer in Japan and a tour with the NDR Hannover Radio SO under Eiji Oue. As well as regular performances in Asia with the Singapore Symphony and all the major Japanese orchestras, Yu Kosuge has worked with many of the leading European orchestras including the NDR Symphony Orchestra Hamburg, NDR Radiophilharmonie Hannover, Berliner Sinfonie Orchester, Radio-Sinfonie Orchester Frankfurt, Camerata Salzburg, St Petersburg Symphony, Orchestre Philharmonique de Radio France and Radio Symphony Orchestra Finland,. Yu Kosuge has performed with conductors of the stature of Seiji Ozawa, Jun Markl, Philippe Herreweghe, Rudolf Barschai, Alexander Dmitriev, Gerd Albrecht, Lawrence Foster, Sakari Oramo, Christian Arming, Yutaka Sado, Osmo Vanska,  Vasili Petrenko  and Dennis Russell Davies.
She has been invited to festivals in Rheingau, Schleswig-Holstein, Bremen, Mecklenburg-Vorpommern, Passau, Braunschweig, Kissingen, at the Salzburger Festspiele, Mozartwoche Salzburg, Holland Music Festival, Piano Festival Lille, La Roque d’Antheron piano festival and La Folle Journee de Nantes, France.
In addition to her busy concert schedule in Europe, Yu performs regularly in Japan, where her tours with the Finnish Radio Symphony Orchestra and Sakari Oramo, Seiji Ozawa and the New Japan Philharmonic inspired rave reviews and great public acclaim.
In September 2009 Sony released Mendelssohn's First Piano Concerto with Mito Chamber Orchestra/Seiji Ozawa and selections from Songs Without Words. This is her 10th CD, since her first disc featuring the Chopin Etudes (accorded a five-star rating by Fono Forum Magazine). Yu Kosuge's other recordings on Sony include Liszt’s 12 Etudes d´execution transcendante, Chopin’s Preludes and Nocturne, Mozart’s Piano Concertos, Fantasie and  Live at Carnegie Hall. Yu Kosuge’s plans include recording the Beethoven's 32 Sonatas over the next few years.
