[1] Despite its name, it is not the administrative or the commercial centre of the city, roles which are designated to Urawa-ku and Ōmiya-ku respectively.

The easternmost of these plateaus is the Ōmiya-daichi, to the west of which lies the Kōnuma River which is at the centre of a 500-meter long depression.

[3] Despite the apparent lack of farming areas, some can be seen on either side of the Kōnuma River where, on the eastern bank, the ward office, fire station and library are also located.

Plans to dissolve the town and merge with Urawa and Ōmiya were rejected by a referendum in 1955, and Yono was raised to city status on July 15, 1958.
