That plant is kudzu — kuzu in Japanese, Pueraria montana var. lobata. It’s native to Japan, not an introduced invasive, but it behaves like one on roadsides and vacant lots.
It grows up to thirty centimeters a day in summer and forms dense mats that smother everything underneath. The leaves are compound — three large leaflets each — and the stems root wherever they touch the ground, so a patch expands fast.
In Japan the starchy roots make hon-kuzu starch for sweets like kuzumochi, and it’s one of the seven autumn flowers. But land managers hate it — cutting the vines barely helps because the underground tubers keep sending up new growth.
