Wildflowers: Humulus Japonicus or Humulus Lupulus? (and, wild berries?)

Hi there !

I'm an expat in South Korea, and I came across those guys below while going to work:

Now, they look like hops, but are they Lupulus or Japonicus?

1st spot:




2nd spot:



3rd spot:



And the bonus one, a berry bush I've found next to those hops:
Some kind of Rubus something?



Cheers !

 

Well... None to help me out with those?

 

I don't know this plant well, but Humulus japonicus is native in Korea, lupulus is not. H. japonicus has leaves with 5-7 lobes, lupulus 3-5.

The last photo sure looks like Rubus, but I couldn't go any further with ID.
