Tenshaen is a nationally designated site of natural beauty located in Uwajima, in Ehime prefecture. It was established as a retirement garden for Date Munetada, seventh lord of Uwajima han, in 1866, and served as a meeting place for Imperial loyalists such as Saigô Takamori, Ômura Masujirô, and Takano Chôei. The site was previously, since the late 17th century, a seaside mansion for the Uwajima daimyô.
The garden's name derives from a poem written by Date Masamune. Munetada, also known as Shunzan, especially enjoyed tea, and calligraphy, and included in the a tea house called Sen'enkan which, years later in 1922, was famously visited by the Shôwa Emperor when he was still Crown Prince. He also included a calligraphy hut, called Harusame-tei. Constructed without nails, in a traditional manner, Harusame-tei still stands today and is considered a valuable piece of architectural heritage.
