Senganen Garden (仙巌園), also known as Isoteien (磯庭園), is a Japanese style landscaped garden along the coast north of downtown Kagoshima. One of the garden's most striking features is its use of Sakurajima and Kagoshima Bay as borrowed scenery. The garden also includes small ponds, streams, shrines and a bamboo grove.
Senganen was constructed in 1658 by the wealthy Shimazu Clan, one of the most powerful feudal clans during the Edo Period (1603-1867). The Shimazu ruled the Satsuma domain (present-day Kagoshima) for almost 700 years until the end of the feudal age in 1868. They continued to be influential into the modern era as some of the earliest adopters of Western science and technology.
At the centre of the garden stands the Iso Residence. The residence was originally built in 1658 along with the rest of the garden, but the current building mostly dates back to a mid-1880s reconstruction. After the end of the feudal age, the Iso Residence became the main residence of the Shimazu family, and its rooms are preserved in the way they were used in the 1890s. https://www.japan-guide.com/e/e4602.html
