Yu Kobayashi & Ryoko Shintani is a Japanese collaborative artist credit used for music released under both performers' names, including anime-related songs, character performances, and other shared credits. It helps listeners find openings, endings, and related vocal tracks that may be credited jointly or searched under either name.
The Ryoko Shintani side of the credit refers to 新谷良子, a Japanese J-pop singer born on March 31, 1981, in Kanazawa and associated with Lantis. Her official website is shintaniryoko.com, and that background places the credit within the broader anime and anison scene, where voice-related releases and theme-song work often overlap. Rather than functioning as a traditional solo biography, this page organizes shared material attributed to Yu Kobayashi and Ryoko Shintani in one place for anime music searches.
