Rosa rugosa (rugosa rose, beach rose, Japanese rose, Ramanas rose, or letchberry) is a species of rose native to eastern Asia, in northeastern China, Japan, Korea and southeastern Siberia, where it grows on beach coasts, often on sand dunes. It should not be confused with "Rosa multiflora", which is also known as "Japanese rose". The Latin word "rugosa" means "wrinkled", referring to the wrinkled leaves.
