Looks like they're using a combination of metal and bamboo scaffolding to help support everything. I had the same initial worry, but it might be fine. A reverse image search didn't immediately turn up the same building. If it's in Tokyo, I wanted to walk by and see for myself (though I don't think I'd take picture; that feels a bit creepy).
Climbing vines like that have a tendency to tear into cracks in whatever they're climbing, increasing water ingress. They also tear off the protective layering on brick/concrete walls.
