Glover Garden (グラバー園 Gurabāen?) is a park in Nagasaki, Japan built for Thomas Blake Glover, a Scottish merchant who contributed to the modernization of Japan in shipbuilding, coal mining, and other fields. In it stands the Glover Residence, the oldest Western style house surviving in Japan and Nagasaki's foremost tourist attraction.
It is located on the Minamiyamate hillside overlooking Nagasaki harbor. It was built by Hidenoshin Koyama of Amakusa island and completed in 1863. It has been designated as an Important Cultural Asset. As the house and its surroundings are reminiscent of Puccini's opera, it is also known as the "Madame Butterfly House." Statues of Puccini and diva Miura Tamaki, famed for her role as Cio-Cio-san, stand in the park near the house. This house was also the venue of Glover's meetings with rebel samurai particularly from the Chōshū and Satsuma domains.
The Glover Residence is noted for its blend of Western and Japanese elements and is an example of treaty port building. This type of architecture closely resembles one-story bungalows used by foreigners in Hong Kong or Shanghai and imported to Japan by British traders. Rather than following contemporary Victorian styles, this type of building more closely reflects the Georgian aesthetic popular in Britain during the previous generation.
The stone-floored verandas, latticed arches, and French windows are several of the distinctive foreign elements included in the residence, while Japanese influence can be seen in the tile roof with its demon-headed tiles intended to ward off evil. The roof was modified by adding unmistakably British chimneys.
