01 ／ Koma District

Jakkō, who led the district,is still enshrined here.

In 716, in the Nara period, 1,799 people of Goguryeo descent living in seven provinces, among them Suruga, Kai and Sagami, were moved here to form Koma District (高麗郡). Koma no Konikishi Jakkō (高麗王若光), held to be its head, is enshrined at Koma Shrine (高麗神社), whose chief priests are still his descendants. At nearby Shōden-in (聖天院) stands a stone tower said to be his grave. The district's name lasted until 1896.

02 ／ Red spider lilies

In a 22 ha purse-shaped bend,five million blooms.

Kinchakuda (巾着田) is a flat of about 22 ha, some 500 m across, enclosed by a great meander of the Koma River. Seen from Mt. Hiwada (日和田山), it looks like a drawstring purse, a kinchaku, which gave it its name. In autumn, some five million red spider lilies (manjushage, 曼珠沙華) are said to bloom in the woods, like a red carpet. In 2016 the city added the flower to its city flowers.

03 ／ Waste

Burnable waste is not burned:it becomes cement.

In 2002 the city stopped burning waste at its ageing incineration centre and began sending burnable waste to the Taiheiyo Cement Saitama Plant in the city. The waste is fermented for about three days into raw material and fuel for cement, then fired at 1,450 degrees. No incineration ash is left, and the city's waste recycling rate is 99.8%.
