As Kelb said, it can reasonably translate to real life if you find an appropriately sized stick. Fencing doesn't have that as much as kendo, since in kendo you train with a bamboo sword, which is balanced very differently from fencing swords and much closer to a random stick (weight will differ still though). Might be why they teach jodo a lot at the same dojos as kendo around here.
Eskrima's prolly good as well, but that isn't sword-only.
What kind of swordfighting is most useful in real life, actually?
Where I'm from, I hear you're not allowed to carry even replica swords. You need to keep them in a box or some other form of casing.
