If you go further along Shin-ohashi-dori St., there will be an explanation version of "Map Gosho Ruins" on the left walking path (near 2-12 Nihonbashi Kayabacho).
The "Map Gosho" was located in the residence of Tadataka Ino (1745-1818), who is known for producing the first full map of Japan based on actual measurements.
Tadataka Ino has been surveying all over Japan since 1800 (1800), surveying the coasts of Japan for the next 17 years, and the total distance has reached about 40,000 km. .
In 1814 (1814), Tadayoshi returned from surveying in the Kyushu region and moved to the current location, which was called Hatchobori Kamejima-cho. The site of this mansion was about 150 tsubo, but it was used not only as a place of residence for loyalty, but also as a map use place for creating survey maps.
Tadataka died at his home in Kamejima-cho in 1818 (1818) before the map was completed, but Tadataka's home was used as a map palace, and in 1821 (1821) "Dainihonenkaiyozenzu" was completed by the help of the subordinates of the astronomy.
After further, you will go to the intersection with Yaesu Street.
At the left end of this intersection is Kameshima Bridge, at which time there is also the "Horibe Yasubei Takeyuki Monument" (Monoshiri Encyclopedia; page 55). The Kamejima River still remains under Kameshima Bridge, and it is one of the few active bridges, which was replaced in 2002 (Monoshiri Encyclopedia; page 56).
