More a trellis than a pergola. I think the glosses can stand here without extra explanations.

…and plenty of Google images, showing the structure.

Quoting ja:WP:
パーゴラ（pergola）は、...棚。
日陰棚、つる棚、緑廊のこと。
日本では藤棚が一般的である。

* Add precise term
* Sort defn into proper equivalent terms
* Add explanation for clarity
Primarily used for horizontal structure so that wisteria can hang *down*. This is formally a “pergola”, hence fronted.
ja:WP gives 藤棚 as the archetypal Japanese example of a パーゴラ (pergola).
“trellis” is common, though ambiguous (more precisely vertical structure, w/o the vines trailing), and “arbor” is also used, again v. ambiguous (more generally a bunch of trees).
