Seikantei was built in 1906 (Meiji 39) in Odawara-machi, Ashigarashimo-gun, Kanagawa Prefecture (present-day Minami-cho, Odawara City) as a villa for Marquis Kuroda Nagashige, who was active during the Meiji era. Located on a south-facing slope of the outer earthen rampart of the former Odawara Castle's third bailey, on clear days, the main house offers a panoramic view of Sagami Bay, including the Manazuru Peninsula and Oshima Island, as well as the Hakone Mountains. The building has an unpretentious sukiya-style design, with a single-story and a two-story building connected together. Inside the building, one can see excellent design elements such as painted wooden sliding doors and woven bamboo ceilings.
In 2005, Seikantei was designated a National Registered Tangible Cultural Property. Currently, it is a facility of Odawara City and has been open to the public since 2010.
The facility also includes a café where you can enjoy coffee and matcha while overlooking the garden and Sagami Bay. Seasonal exhibitions, concerts, and other events are held irregularly.
