most obesh cresh plant japan

It seems like you’re asking about the “most obese or trash plant in Japan.” However, the phrasing is a bit unclear. Here are two possible interpretations and answers:

1. Most Obese (Largest/Biggest) Plant in Japan
If you’re asking about the largest or most massive plant in Japan, one notable example is:
– Japanese Giant Knotweed (*Fallopia sachalinensis*) – An invasive plant that grows very large (up to 4–5 meters tall).
– Giant Bamboo (*Phyllostachys edulis*) – Some species can grow extremely tall and thick.

2. Most Trash (Worst Invasive/Problem Plant) in Japan
If you mean the most problematic or “trash” plant (invasive, harmful, or unwanted), then:
– Kudzu (*Pueraria montana*) – Known as “the vine that ate the South” in the U.S., but also invasive in Japan.
– Japanese Knotweed (*Reynoutria japonica*) – Highly invasive, damages infrastructure, and spreads aggressively.
– Water Hyacinth (*Eichhornia crassipes*) – Clogs waterways and is hard to control.
