Hello. It is a pine tree from Kakigara-cho, a doboku correspondent. The office is located in Nihonbashikakigaracho. In this area, many Samurai residence was located in the Edo period.
I was told by an acquaintance that Kakigara-cho has a deep relationship with the civil engineering world! It seems that Kimi Furuichi (1854.9.4-1934.1.28), the first chairman of the Japan Society of Civil Engineers, was born in Nakayashiki in the Himeji clan in Kakigara-cho (* 1). When the location of this Nakayashiki was confirmed on an old map (* 2), it was located on the east side of "Tokanbori" and on the west side of "Kakigara Ginza". It is currently 1-chome Kakigaracho, Nihonbashi. Isn't it a city that walks every day?
Kotake Furuichi was awarded the first doctor of engineering in Japan, and Dr. Doki of the Ministry of Internal Affairs and Communications, Director of the Institute of Technology, River Law and Sabo Law, Yodo River Renovation, Osaka Port, Yokohama Port, Tokyo Port, Ashio Copper Mine poisoning incident investigation, and Chuo-ku The predecessor of the Ginza Line Subway Line, which is closely related to Tokyo Metropolitan Expressway Co., Ltd. (President: Asakusa to Shimbashi). By the way, speaking of the Tokyo Metropolitan Subway, the father of the Subway, Tokuji Hayakawa was involved in the establishment. There's a bust on the underground passage of Ginza Station.
Kotake Furuichi is also included in the 48 people of "Civil Engineering Great Karuta" (* 3) issued by the Japan Society of Civil Engineers.
Furuichi is not well known in general, but it is one of the people who have made great achievements in the development of Japan, so if you are interested, please take a look at the website of the Japan Society of Civil Engineers.
