I believe I understand what "Uchiha Kaenjin" means now...
Being noted earlier Ka is in the word which probably signifies fire.. (aka
katon suiton)..but what does enjin mean? Did some research and came across words like "ring" and "barrier".
Uchiha signifies its an jutsu that only Uchiha can use..
"KA"= Fire "ENJIN"=RING/BARRIER
It makes sense since the forcefield seems to be in a cylindrical shape...

So the technique in a rough translation would probably sound something like
"Uchiha's Flame Ring" "Uchiha's Fire Barrier" or something across those lines
Thoughts?
This obviously means Uchiha Kaenjin is not Tobi's name.
