Waterways, a city, and an economic engine

The review begins with a claim about period. Edo, from 1603 to 1867, is not a closed prelude. It is, in this telling, the foundation of modern Japan. Tokugawa Ieyasu and the waterways come first, above all the Tamagawa aqueduct, read as a matter of technology and of organization, not of ornament.

From there the review turns to the city itself — Edo, later Tokyo — and to sankin-kotai and tenka-bushin. Sankin-kotai, the system of alternate attendance, is argued as an economic engine rather than a waste. The movement of retinues, in this reading, circulated goods and people; it did not merely drain domains.

Schools, a map, and learning from the Dutch

Education is given a large place. Confucianism appears through commentaries, through terakoya, and through domain schools. Terakoya were private schools that taught reading, writing, and arithmetic to the children of commoners. They expanded in late Edo and, as the review evaluates it, underpinned a high level of literacy. Confucianism itself is said to have evolved toward the practical, in what the review calls an era of reading books. Ino Tadataka’s map of Japan sits in the same current: a practical, measured picture of the country.

Rangaku, Western learning, entered through the Dutch factory in Nagasaki. The review dates a starting point to 1774, when Sugita Genpaku and others translated a Dutch anatomy text as Kaitai Shinsho. From that beginning, it says, the current later reached medicine, astronomy, and geography. Those steps are left as the review leaves them. Later historiography is not added.
