I used to live at the top of a steep hill. Actually more like up on a plateau, so I could ride up the hill past my house and do a little 4 block loop for cool down before stopping. If I just stopped directly after climbing the hill, I sometimes wouldn't feel so well after stopping. Looks like that Kuota of yours has low enough gearing for the task.
I'd be more worried about heading down the hill in the fall if there are deciduous trees in the neighborhood. I've gone down in leaves on a number of occasions.
