美浜大橋, Road bridge at the mouth of Hanami River in Mihama-ku, Japan.

The Mihama Bridge is a road bridge crossing the Hanami River mouth, with dedicated pedestrian paths alongside vehicle lanes. It connects the Makuhari and Kemigawa areas while allowing walkers to move freely between the two sides.

The bridge carries Haibin-dori (the city road Chiba Rinkai Line) over the mouth of the Hanami River in Mihama-ku, Chiba. From the mid-to-late 1990s the wide, lightly trafficked roads around Makuhari made it the largest car-cruising pickup spot in the Kanto region, nicknamed Nanpa-bashi. Car pickup faded after the 2000s, but the views kept cars lining the roadside, prompting the city to open the Haibin-dori observation parking lot in 2015; it was rebuilt and made paid from 1 October 2019.

From the mid-1990s to the late 1990s, when car-based pickup spots existed across Japan, Mihama Bridge was the largest in the Kanto region and was nicknamed "Nanpa Bridge". On weekends, lines of cars carrying women stretched 2-3 km along the wide, low-traffic roads of the then-developing Makuhari area, while cars of men drove slowly alongside.

Walking across the bridge is straightforward from either side, with clear pedestrian paths offering views as you move along. The best time to walk is in early morning or late afternoon when light conditions make the views more enjoyable.

On weekends, lines of cars carrying women stretched 2-3 km, while cars with men cruised slowly alongside to call out to them. The wide roads and light traffic around Makuhari, then still developing, made it ideal for car-based flirting.
