Is it my responsibility to prune the tree on my property?

So I’m in a rented house in Tokyo.

It’s not a big property, so there’s no front or back yards.

However there’s this small tree next to my mailbox, like 6 feet tall maybe.

It’s starting to grow branches and leaves, and while it’s not hitting my mailbox, I think it’s reaching into the neighbor’s side over the wall.

I didn’t really think much of it, but the reason I started thinking it is cause my intercom showed that some oba-San rang my intercom at 2pm on a Friday.

She looked upset, but it could just be that she was hot.
She didn’t say anything, I just see her in front of my intercom.

I don’t know who she is or what she wants, there was no notes or nothing.

I’m thinking maybe it’s the tree? I have no idea. But I thought maybe I should get it pruned or something.

Or is that something I ask my landlord to do?
