青梅新町の大井戸

There is such a well called "Maimaizu" on the Musashino Plateau. There is also a theory that it was dug in the Kamakura period, no, the Heian period. It is well preserved like the Gonokami Maimaizu Well in front of Hamura Station.

The large well has a funnel shape consisting of a mortar-shaped facility for people to approach the water outlet and a tubular well that pumps water. Wells of this shape are constructed on the Musashino Plateau, where water is difficult to obtain, such as the Maimaizu Well (a historic site designated by the capital) in Hamura City, but they are approximately 22 meters east-west, 33 meters north-south, and 7 meters deep. The large well, which consists of a mortar and the surrounding filling, is the largest of all. It is uncertain when this well was dug, but it is believed to be a style before the generalization of techniques for constructing tubular wells from the surface. In addition, since it is located at the intersection of the two old roads, "Ome Kaido" and "Imaji Road (Chichibu Road)" that run through the wilderness of Musashino, it probably supplies drinking water for people and horses that go on the road even before the development in the Edo period. It seems that it was a place to do it. The development of the new town and village began in 1611 by Nosuke Yoshino, a landlord of the master Oka village, and at that time, a large-scale renovation was added to the large well and it was used as the Shiono family well. It is assumed from the results of the excavation survey and the "Jin-kun Kaimura-ki" that describes the state of the opening of the village. Furthermore, it was clarified that it was still used from the application stone with the year of Meiwa 7 (1770) and the ink book of "Eidai Fusetsusen" excavated from the bottom of the tube well. In this way, Oido is a historic site with high academic value since the precious historical period related to the development of the Musashino Plateau from the late Middle Ages to the early modern period.
