Well this isn't a very happy gardening topic. Japanese knotweed is a terrible invasive weed and it really is one that you'd can't just let go because it can cause serious damage to structures, not to mention waterways and riparian areas.
I'm addressing large knotweed plants in this video because, well, most people don't notice it until it gets to this size. If, however, you spot it when it's small, you can certainly try digging (go for this rhizomatous roots people!) , repeated cutting or other methods spelled out in the fact sheet linked below.
The method I'm using does use chemicals, but this injection method, while tedious, has a very high success rate and is probably the safest way you could use an herbicide.

By the way, knotweed is edible (and tastes a bit like rhubarb). Here's some info on that (obviously this is NOT for areas being chemically managed): https://foragerchef.com/category/wild...
