Early Meiji Architecture was initially influenced by colonial architecture in Chinese treaty ports such as Hong Kong. In Nagasaki, the British trader Thomas Glover built his own house in just such a style using the skill of local carpenters. His influence helped the career of architect who designed the Osaka Mint in 1868, a long, low building in brick and stone with a central pedimented portico. In Tōkyō, Waters designed the Commercial Museum, thought to have been the city's first brick building.
