From August 28 to 31, there was an event hosted by the "Tadataka Ino 200 Years Chuo-ku Festival Executive Committee". .
This is the 27th Complete Restoration Inozu National Tour Floor Exhibition. It was a large exhibition that used the second floor venue of the Chuo Ward Sports Center full.
Tadataka Ino was born in 1745 in Kosekimura, almost in the center of Kujukuri Beach, as a child of Sadatsune Koseki and Mine, as the youngest of the three brothers. Later, after bereavement with his mother, his father, who was the son-in-law, returns to his parents' home with only his brother and sister of Tadayoshi (child name, Jiro).
When Tadayoshi was 10 years old, his father, Sadatsune Jimbo, comes to pick him up and lives with his father until the age of 17. At this time, the sake brewer in Sahara, the Ino Saburoemon family disappeared, and the widow was seeking a son-in-law at the expense of Hirayamaga, a relative of the Jinbo family and the Ino family. .
After that, he demonstrated his business talent at the Ino family and enlivened the family business's sake brewing business until the age of 49. He retired at the age of 49, handed over his family to his son, Keikei, went to Edo to pursue astronomy and calendar, and entered Yoshitoki Takahashi, a 19-year-old Shogunate Astronomical Society.
Despite having the resources, Tadataka Ino, who has a strong spirit of challenge, is here to demonstrate his essence.
He lived in Kuroe-cho near Fukagawa Hachimangu Shrine, went to school to Yoshitoki Takahashi of the calendar station in front of the storehouse in Asakusa, and set up a observatory at home to observe it eagerly.
When the size of the earth became a hot topic among the calendar scholars, I knew that the difference in latitude between Asakusa and Kuroe-cho was one and a half minutes, so I guess, "I'm going to measure the distance between the two points, I'll decide the distance between Asakusa and Fukagawa, but from the time of my teacher, I think I
'll decide the distance between Asakusa and Fukagawa.
At the age of 55, he takes a step in Ezo survey to measure the length of one latitude. On April 19, 1800, he visited Hachimangu Shrine Fukagawa and left for Ezochi via Senju-juku.
In the second survey, we measured the eastern shore of Honshu from Izu. The results of the first and second surveys were recognized, and from the next third survey, the Shogunate announced that it would be possible to use horses for travel without rent, and the quantity was greatly increased, The village village has now received much generous assistance. The third survey surveyed the Uetsu region, and the fourth survey surveyed the coasts of Tokai and Hokuriku, aiming to produce a whole map of East Japan.
The following references show that the survey equipment used at this time was called "intermediate quadrant". At the venue, other surveying instruments were also exhibited.
The results of the four surveys from the first to the fourth are compiled as "East half of Japan Coastal Map", which has been well received at the Shogunate, and has been overviewed by the 11th Shogun Ienari Tokugawa.
According to the 4th survey route map, at this time, the Tokaido was re-measured to Numazu, connected to the Izu Peninsula survey line in Numazu, and began coastal surveys along the Tokaido, followed by Ejiri, Miho Matsubara, Omaezaki, Atsumi Peninsula, and Chita Peninsula, and went from Atsuta to Nagoya Castle to Gifu, Okunigaki, Sekigahara, and Kinomoto from Tsuruga. At this time, I was 58 years old because it was October 7, 1803.
After that, under the order of West Japan Survey, the 5th and 6th surveys continued. In the fifth edition, we also survey Kyoto, where the cityscape is well-equipped.
It doesn't seem to be much different from the map used in modern timetables.
In the sixth installment, I also work on surveying Itsukushima.
It's a pity that everything you've introduced at this event cannot be expressed on this small blog.
"Tadataka Ino" Daisensei's vigorous curiosity and challenge spirit, I thought that I had to live happily in my future life.
I would like to express my deepest respect to the organizers and everyone who cooperated. Thank you very much.

When I thought it was getting cooler in the morning and evening, the autumn scenery was already spreading here in Tsukiji River Park in Akashicho.
Pampas grass, also known as Shiroganeyoshi. It is a plant of the family Riceaceae and has a large presence.
In naturalized species, the appearance of cream-colored spikes swaying in the wind in the backlight creates the autumn of Japan.
