Shonan Pandora is a Japanese Thoroughbred racehorse and broodmare, best known for her victory in the 2015 Japan Cup. After finishing second on her only start as a juvenile in 2013 the filly made steady progress in the following year and won the Grade 1 Shuka Sho on her penultimate appearance. She reached her peak in 2015 when she finished third in the Takarazuka Kinen, won the Sankei Sho All Comers and ran fourth in the Tenno Sho before defeating a strong international field to take the Japan Cup. Her performances that year saw her being awarded the JRA Award for Best Older Filly or Mare. She was retired from racing after finishing third twice as a five-year-old.
