The KM Shimano Family Foundation is tightly focused on marine conservation, especially protection, rescue and rehabilitation of marine mammals and coastal ecosystems. They fund a mix of rescue centers, regional aquariums, and advocacy/coastkeeper groups across the U.S. (notably California and Maine) and select international marine conservation work. Grants are framed as program support for organizations working directly to protect ocean wildlife and habitats.
The KM Shimano Family Foundation repeatedly directs its largest recent grants to marine mammal and ocean-wildlife work. In 2025, it gave $35,000 to The Marine Mammal Center in Sausalito, California, and the same amount to Aquarium of the Pacific in Long Beach, California, both to further efforts to protect the ocean and ocean wildlife. That pattern matches a broader grant program built around marine environment conservation, including rescue and rehabilitation, scientific ocean research, legislative work, and education and engagement tied to coastal protection. The foundation’s recent grants show a clear preference for organizations that work directly with marine species and habitats. Marine Mammals of Maine received $25,000 in 2025, while Save the Manatee Club received $34,000 in 2024 for the same stated purpose. California Coastkeeper Alliance, through the Otter Project, also appears in the recent grants list, pointing to support for species-specific conservation and coastal advocacy. The foundation funds nonprofit organizations, not individuals, and its grantmaking is described as competitive and open to unsolicited requests through a donation or partnership process. Recent awards suggest a steady emphasis on program support for groups active in rescue, rehabilitation, research, education, and policy work.
Marine mammal rescue and rehabilitation is a core theme. The foundation gave $35,000 to The Marine Mammal Center in 2025 and $25,000 to Marine Mammals of Maine in 2025, both for efforts to protect the ocean and ocean wildlife. Species-specific conservation also appears in its grantmaking. Save the Manatee Club received $34,000 in 2024, and California Coastkeeper Alliance (the Otter Project) received $20,000 in 2024, showing support for manatee protection and otter-related coastal work. The foundation also backs public-facing marine institutions and regional education. Aquarium of the Pacific received $35,000 in 2025, and National Marine Life Center received $20,000 in 2024. These grants align with the foundation’s stated support for marine education, scientific ocean research, and coastal protection.
Typical grant size centers around $20,000, with a p25 of $12,925 and a p75 of $31,750. The recent grant list shows repeat awards to the same organizations across multiple years, including The Marine Mammal Center, Marine Mammals of Maine, California Coastkeeper Alliance, and New England Coastal Wildlife Alliance, which suggests ongoing relationships rather than one-off awards. The foundation is a family foundation, funds organizations rather than individuals, and does not make program-related investments. Its grant programs accept unsolicited requests and use a donation or partnership application process.

Grantmaking is national, but it is heavily tilted toward California, the top state by grant count. Recent recipient cities include Sausalito, Long Beach, Sacramento, Brunswick, Buzzards Bay, Longwood, and Middleboro. The list also includes one grant to Lewes, Delaware and one to Fort Lauderdale, Florida, but every recent grant in the data went to a U.S. recipient.
