A teahouse and Western-style building that symbolizes the beginning of the modern tea industry in Shizuoka, it is called a "tongariyane" because of the features of its appearance. When the export of tea from Shimizu Port started, in order to open up a trade route for direct export, a "reproduction (processing) plant" controlled by foreign capital was established. Built in 1902 as an office at one corner of the plant, the memorial building contributed greatly to the internationalization of Shimizu Port as well.
