Ume-san.
Today is the second good place in Chuo-ku @ Nihonbashi.
This is the famous water Shirakiya well behind Cored Nihonbashi. Residents of Nihonbashi during the Edo period While struggling to secure good water, it seems that Shimizu was made sideways so that Hikotaro Omura, the second generation head of Shirakiya, who was a kimono merchant, dug a well and offered it to the Shoguns. At present, a stone monument stands in Designated Cultural Property, Tokyo. (Refer to the official Textbook of Chuo-ku Tourism j Certification)
There is also a place behind the main street where you can feel the history of the Edo period, so be sure to go there!
