Not if we're speaking anatomically. The lower back is the area the lumbar region of the spine passes through (and technically would be the region rinkaku have their kakuhou). The sacrum and coccyx are counted as part of the pelvis, which isn't really considered part of the back.

But, eh, I'll give you this one since TG apparently means the entire posterior region sans limbs when it says "back". XP
