## About

The Ryuji Ueno Foundation was established in 2015 as a 501(c)(3) nonprofit by Dr. Ryuji Ueno, a Japanese physician-scientist and entrepreneur whose wealth stems from co-founding Sucampo Pharmaceuticals and founding R-Tech Ueno, Ltd. His foundational biopharmaceutical work, particularly on prostones, led to the development of Amitiza, a drug for chronic constipation and IBS-C. The foundation operates from Washington, D.C., where Dr. Ueno maintains close ties to the city's cultural and diplomatic fabric, including ownership of the historic Evermay Estate in Georgetown. The foundation's programmatic strategy is singularly focused on classical music, structured around three pillars: artist development, audience expansion, and instrument access. It provides direct grants and performance opportunities to emerging pianists and conductors, most notably underwriting debut appearances at prestigious venues. A defining capital asset is its collection of rare stringed instruments — including the 'Lord Wandsworth' Stradivarius violin — which it loans to promising artists for concert use. The geographic footprint spans the United States, Europe, and Japan, with a particular concentration on facilitating trans-Pacific cultural exchange between American institutions and Japanese musicians (public record). The foundation's public-facing operations are led by Artistic Director Ryo Yanagitani, a concert pianist who shapes the grantee selection and programming. Dr. Ueno's ex-wife and long-time business partner, Dr. Sachiko Kuno, runs a separate but adjacent philanthropic entity, the S&R Foundation (now operating as S&R Evermay), which also emerged from the Sucampo wealth and shares an overlapping interest in arts and science. Dr. Ueno is a member of the Shenandoah University Conservatory Advisory Board and serves as the Branch President of the Omotesenke Domonkai Eastern Region USA, a traditional Japanese tea ceremony association, signaling a deep personal commitment to cultural preservation that runs parallel to the foundation's music mission (public record). The foundation's structural differentiator is its instrument-lending program. Unlike most arts grantmakers that solely provide cash, The Ryuji Ueno Foundation owns and maintains concert-grade assets — multimillion-dollar violins — and places them directly into the hands of the artists it supports. This creates a durable, asset-backed patronage model that combines a traditional 501(c)(3) grantmaking structure with the operational logistics of a cultural institution and the balance-sheet strategy of a private collection.

## Questions

### What is the relationship between The Ryuji Ueno Foundation and the S&R Foundation?

The two are legally distinct but historically and personally intertwined. The S&R Foundation (now S&R Evermay) was co-founded by Dr. Ryuji Ueno and his ex-wife, Dr. Sachiko Kuno. While the S&R Foundation has a broader mandate spanning arts and sciences, The Ryuji Ueno Foundation is solely Dr. Ueno's vehicle, specifically focused on classical music. Both entities grew out of the wealth generated by Sucampo Pharmaceuticals.

### How does The Ryuji Ueno Foundation source the artists it supports?

The foundation does not operate a public open-call grant cycle. Artist selection is curated internally by Artistic Director Ryo Yanagitani, drawing on his professional network within the international classical music circuit. Support often culminates in high-profile performance debuts, such as underwriting a pianist's appearance at the Salzburg Festival.

### What is the significance of the Stradivarius violins in the foundation's mission?

The instrument collection, which includes the 'Lord Wandsworth' Stradivarius, functions as a non-monetary grant. By loaning multimillion-dollar instruments to artists, the foundation directly elevates their performance capability and career trajectory without requiring them to secure their own instrument financing. This is a rare model in philanthropic arts funding.
