Urawa Unagi — Freshwater Eel District Tradition

Urawa (now part of Saitama City) has served as a freshwater eel capital since the Edo period when the Shiba River and surrounding wetlands teemed with wild unagi. Though modern urban development eliminated wild eel populations, Urawa's eel restaurant tradition endures — over 30 specialized unagi-ya (eel restaurants) cluster within a 1-kilometer radius of Urawa Station, maintaining recipes and techniques passed through generations. Urawa-style follows Edo preparation: eel split lengthwise, steamed to remove fat, then grilled over binchotan charcoal with sweet tare sauce.

The district's concentration of eel expertise creates friendly competition driving quality — each restaurant guards its proprietary tare sauce (some maintained continuously for 100+ years). The price-to-quality ratio is excellent compared to Tokyo — equivalent meals cost 20–30% less in Urawa while maintaining equal or superior quality. The tradition draws eel enthusiasts on pilgrimage from across Kanto, particularly on the traditional Doyo no Ushi (土用の丑, midsummer eel-eating day) when lines extend down blocks.
