Koshigaya, Saitama

Along the embankment of the Motoarakawa, rows of Somei Yoshino stand in the kind of quiet that belongs to weekday mornings — joggers, dog-walkers, the distant rumble of a Tobu line train crossing flat ground. Koshigaya sits in the alluvial plain between two ancient plateaus, threaded by rivers with names that appear on Edo-period maps: the Nakagawa, the Ayasegawa. The old Nikko Kaido, now National Route 4, still passes through, and if you know to look, the proportions of the old post town — Koshigaya-juku — are faintly legible in the street pattern near the historic core.

The city's particular produce is less obvious than its commuter identity suggests. Kuwai, a water chestnut grown in the flooded fields of this river-laced lowland, has been cultivated here for generations. Negi and komatsuna come from the same agricultural belt. The craft traditions run alongside: Koshigaya Hina dolls and Koshigaya armor, both made by hand in the city, occupy a niche that connects festival culture to material skill. Each August, the Minami-Koshigaya Awa Odori fills the streets near Shin-Koshigaya Station with dancers and drums — a transplanted Tokushima tradition that has taken firm root in this suburban soil.

At Shin-Koshigaya and Minami-Koshigaya stations, the Tobu Skytree Line and the Musashino Line meet, and the transfer between them is made on foot. The rhythm of the city runs through these connections — Tokyo reachable in one direction, the flat Kanto interior in the other, while the rivers and fields persist quietly between the platforms.
